From David + Sidrane (2017-03-09). + * EZ80F910200KITG: Missing support logic in configs/Kconfig (2017-03-09). + * Olimex-STM32-P407: Update USB host support (2017-03-09). + * Olimex STM32 P407: USB host support for USB FLASH sticks is now + supported in the base nsh configuration (2017-03-09). + * STM32, STM32 F7, and STM32 L4: Back out part of + 3331e9c49aaaa6dcc3aefa6a9e2c80422ffedcd3. Returning immediately in + the case of a NAK makes the Mass Storage Class driver unreliable. + The retry/timeout logic is necessary. This implementation tries to + implement a compromise: If a NAK is received after some data is + received, then the partial data received is returned as with + 3331e9c49aaaa6dcc3aefa6a9e2c80422ffedcd3. If if a NAK is received + with no data, then no longer returns the NAK error immediately but + retries until data is received or a timeout occurs. Initial testing + indicates that this fixes the issues the MSC. However, I have + concerns that if multiple sectors are read in one transfer, there + could be NAKs between sectors as well and, in that case, then change + will still cause failures (2017-03-09). + * STM32F2: Add USB OTG HS support for stm32f20xxx cores. From Simon + Piriou (2017-03-09). + * Remove all references to arch_usbhost_initialize(). That was + incorrectly called from apps/examples/hidkbd. That is violation of + the OS interfacing rules and will no longer be supported. USB host + should be initialized as part of the board bring-up logic was with + any other devices and should not involve illegal calls from + applications into the OS (2017-03-09). + * STM32, STM32 F7, STM32 L4: OTG host drivers: Do not do data toggle + if interrupt transfer is NAKed. Sugested by webbbn@gmail.com + (2017-03-09). + * apps/examples/usbterm is gone because it can be configured to perform + an illegal call into the OS. Remove all traces of + CONFIG_EXAMPLES_USBTERM* and all of the illegal device support + (2017-03-09). + * Save elapsed time before handling I2C in stm32_i2c_sem_waitstop(). + This patch follows the same logic as in previous fix to + stm32_i2c_sem_waitdone(). It is possible that a context switch + occurs after I2C registers are read but before elapsed time is saved + in stm32_i2c_sem_waitstop(). It is then possible that the registers + were read only once with "elapsed time" equal 0. When scheduler + resumes this thread it is quite possible that now "elapsed time" will + be well above timeout threshold. In that case the function returns + and reports a timeout, even though the registers were not read + "recently". Fix this by inverting the order of operations in the loop + - save elapsed time before reading registers. This way a context + switch anywhere in the loop will not cause an erroneous "timeout" + error. From Freddie Chopin (2017-03-10). + * pthreads: Fix pthread_mutexattr_init(). It was not initializing the + protocol field when priority inheritance is enabled (2017-03-10). + * Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is + only a single, hard-allocated holder structure. This is problem + because in sem_wait() the holder is released, but needs to remain in + the holder container until sem_restorebaseprio() is called. The call + to sem_restorebaseprio() must be one of the last things the + sem_wait() does because it can cause the task to be suspended. If in + sem_wait(), a new task gets the semaphore count then it will fail to + allocate the holder and will not participate in priority + inheritance. This fix is to add two hard-allocated holders in the + sem_t structure: One of the old holder and one for the new holder + (2017-03-10). + * STM32, STM32 F7, and STM32 L4: Clone Freddie Chopin's I2C change to + similar STM32 I2C drivers.

Therefore, we can simplify the + conditional logic of the last PR. Negative logic was used (#ifndef + BOARD_DISABLE_USBOTG_HSULPI) to prevent bad settings in other + configurations. But giveh these facts, the preferred positive logic + now makes more sense (#ifdef BOARD_ENABLE_USBOTG_HSULPI) (2017-03-11). + * STM32: OTG host implementations of stm32_in_transfer() must obey the + polling interval for the case of isochronous and interrupt endpoints + (2017-03-12). + * Photon: Add basic support for wlan chip.

From Simon Piriou (2017-03-14). + * lp_worker: Guard from pend_reprios overlow. From David Sidrane + (2017-03-15). + * wireless/ieee802154: Renamed file ieee802154_device to + radio802154_device. From Anthony Merlino (2017-03-15). + * Add option to enable wireless debug output (2017-03-15). + * wireless/ieee802.15.4: Refactors ieee802154_dev character driver to + be radio802154_device. From Anthony Merlino (2017-03-15). + * Integrate use of new wireless debug macros. Replace ad hoc debug + macros. Convert obsolete dbg() macros to current info(), warn(), + err() macros (2017-03-15). + * sem_holder: Fixes improper restoration of base_priority in the case + of CONFIG_SEM_PREALLOCHOLDERS=0. The call to + sem_restorebaseprio_task context switches in the + sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to + releasing the holder. So the running task is left as a holder as is + the started task. Leaving both slots filled thus failing to perform + the boost/or restoration on the correct tcb. This PR fixes this by + releasing the running task slot prior to reprioritization that can + lead to the context switch. To faclitate this, the interface to + sem_restorebaseprio needed to take the tcb from the holder prior to + the holder being freed. In the failure case where sched_verifytcb + fails it added the overhead of looking up the holder. There is also + the additional thunking on the foreach to get from holer to + holder->tcb. An alternate approach could be to leve the interface + the same and allocate a holder on the stack of sem_restoreholderprioB + copy the sem's holder to it, free it as is done in this pr and and + then pass that address sem_restoreholderprio as the holder. It could + then get the holder's tcb but we would keep the same sem_findholder + in sched_verifytcb. From David Sidrane (2017-03-15). + * ARM: Remove redundant interrupt stack coloring.

From Jussi Kivilinna + (2017-03-17). + * vsnprintf(): If size is zero, then vsnprintf() should return the + size of the required buffer without writing anything. This is same + fix that was done for snprintf in 2014 by commit + 59846a8fe928abb389e3776ebdbb52022da45be3. From Jussi Kivilinna + (2017-03-17). + * Adds driver support for the XBox One controller.

From Mateusz Szafoni + (2017-03-18). + * mtd/progmem: fix incorrect target address calculation. + progmem_read/write() is incorrectly calculating the target address, + expecting the offset argument is given in a block number. This is + completely wrong and as a result invalid flash region is accessed. + Byte-oriented read/write interfaces of mtd device accept the target + address in a byte offset, not a block number. From Heesub Shin + (2017-03-18). + * STM32F33: Move DMA logic to a separate files + add ADC support. From + Mateusz Szafoni (2017-03-18). + * Nucleo-F334R8: Add COMP support.

From Anthony Merlino (2017-03-21). + * Implement DMA support for the stm32f4 I2C. Max and I have verified + that it works on our systems. From rg (2017-03-21). + * drivers/lcd/st7565.c: Use ST7565_POWERCTRL_INT instead of + ST7565_POWERCTRL_BRF. From Masayuki Ishikawa (2017-03-21). + * SMP Kconfig: Change the minimum SMP_NCPUS to 1. From Masayuki + Ishikawa (2017-03-xx). + * SMP: Setting CONFIG_SMP_NCPUS=1 should only be permitted in a debug + configuration (2017-03-22). + * Clicker2-STM32: Create src/, kernel/, and scripts/ directories + (2017-03-22). + * Clicker2-STM32: Add an NSH configuration (2017-03-22). + * Clicker2 STM32: Add SPI support (2017-03-22). + * XMC4xxx: Add FPU support. From David S. Alessio (2017-03-22). + * Clicker2-STM32: Add definitions for remaining mikroBUS pins + (2017-03-22). + * STM32: Fix erase sector number for microcontrolers with more than 11 + sectors. Erase a sector from the second bank cause the bit 4 of SNB + being set but never unsed, so trying to erase a sector from the first + bank was acually eraseing a sector from the second bank. From José + Roberto de Souza (2017-03-22). + * STM32: Make up_progmem thread safe. Writing to a flash sector while + starting the erase of other sector have a undefined behavior so lets + add a semaphore and syncronize access to Flash registers. But for + the semaphore to work it needs to be initialized so each board needs + call stm32_flash_initialize() on initialization, so to avoid runtime + problems it is only using semaphore and making it thread safe if + initialized, after all boards starts to call stm32_flash_initialize() + we can remove the boolean and the check. From José Roberto de Souza + (2017-03-22). + * STM32: Add workaround for flash data cache corruption on + read-while-write. This is a known hardware issue on some STM32 see + the errata of your model and if you make use of both memory banks you + should enable it. From José Roberto de Souza (2017-03-22). + * Clicker2-STM32: Add framework for MRF24J40 support. Untested and + still some missing logic (2017-03-22). + * STM32 Flash fixes. From José Roberto de Souza (2017-03-22). + * STM32F7: In stm32_allocateheap.c There are 5 not 4 configurations. + From David Sidrane (2017-03-23). + * Clicker2-STM32: Add logic to register the MRF24J40 radio character + device (2017-03-23). + * Clicker2-STM32: Add some mostly bogus MAC initializatinon logic + (2017-03-23). + * STM32 I2C: Do not allow CONFIG_I2C_POLLED and CONFIG_I2C_DMA. From + rg (2017-03-23). + * stm32_flash: Need conditinal on non F4 targets. From David Sidrane + (2017-03-23). + * stm32_i2c_alt: Duplicate non CS dev of regval. From David Sidrane + (2017-03-23). + * stm32f40xxx_i2c: Duplicate non CS dev of regval. From David Sidrane + (2017-03-23). + * stm32_i2c_alt: Move def of regval to top func def per CS. From + David Sidrane (2017-03-31). + * stm322_flash: Missing unlock on F1 HSI off path. From David Sidrane + (2017-03-24). + * Fix compile error when disabled the flash data cache corruption for + stm32 f1xx. From no1wudi (2017-03-24). + * The interrupt occurs over the counter overflow. From Aleksandr + Vyhovanec (2017-03-24). + * I needed to use DS3231, I remember that in past it worked ok, but now + for stm32f4xx is used another driver (chip + specific, stm32f40xxx_i2c.c) and DS3231 driver doesn't work. After + investigating a problem I found that I2C driver (isr routine) has a + few places there it sends stop bit even if not all messages are + managed. So, e.g., removing stm32_i2c_sendstop (#1744) and adding + stm32_i2c_sendstart after data reading helps to make DS3231 working. + From Alexander Oryshchenko; verified by David Sidrane (2017-03-24). + * wireless/ieee802154: Adds IOCTL definitions for accessing PHY + layer. From Anthony Merlino (2017-03-24). + * Add ffsl(), ffsll(), fls(), flsl(), flsll() and use GCC's + __builtin_ctz/__builtin_clz for faster implementation of these. From + Jussi Kivilinna (2017-03-24). + * MRF24J40/Clicker2: Add an MRF24J40 radio configuration to the + Clicker2 STM32 board. Fix a few errors discovered during build + (2017-03-24). + * configs/: Rename all stm32_wireless.c files to stm32_cc3000.c + (2017-03-24). + * configs/: Rename all xyz_wifi.c files to stm32_cc3000.c (2017-03-24). + * Clicker2-STM32: Add usbnsh configuration (2017-03-25). + * drivers/analog: Add basic COMP driver.

From Mateusz Szafoni + (2017-03-25). + * stm32/Kconfig: Update COMP and OPAMP definitions. From Mateusz + Szafoni (2017-03-26). + * pthreads: Add more robustness characteristics: pthread_mutex_lock() + and trylock() will now return EOWNERDEAD if the mutex is locked by a + thread that no longer exists. Add pthread_mutex_consistent() to + recover from this situation (2017-03-26). + * pthread: Fix return value of pthread_give/takesemaphore(). Add + option to pthread_takesemaphore to ignore EINTR or not (2017-03-26). + * pthreads: Partial implementation of final part of robust mutexes: + Keep list of all mutexes held by a thread in a list in the TCB + (2017-03-26). + * when pthread exits or is cancelled, mutexes held by thread are marked + inconsistent and the highest priority thread waiting for the mutex is + awakened (2017-03-26). + * pthreads: Add a configuration option to disable robust mutexes and + revert to the traditional unsafe mutexes (2017-03-26). + * pthread mutexes: Add option to support both unsafe and robust + mutexes via pthread_mutexattr_get/setrobust() (2017-03-26). + * pthread mutexes: Finish logic to support configuration mutex + robustness (2017-03-27). + * Rename CONFIG_MUTEX_TYPES to CONFIG_PTHREAD_MUTEX_TYPES (2017-03-27). + * Make sure that CONFIG_PTHREAD_MUTEX_ROBUST=y is selected every + configuration that enabled pthreads (2017-03-27). + * Add syscall support for pthread_mutex_consistent() (2017-03-27). + * Include wcstold in C++ cwchar header file. From Alan Carvalho de + Assis (2017-03-27). + * AT86RF23x: Clean-up, standardize lower half interface. Take + advantage of new OS features for interrupt parameter passing + (2017-03-xx). + * MRF24J40: Take advantage of new OS features for interrupt parameter + passing (2017-03-27). + * lcd/: PCF8574 backpack logic needs to include poll.h + CONFIG_DISABLE_POLL is not set (2017-03-27). + * drivers/analog: Add driver for the LTC1767L ADC. From Martin + Lederhilger (2017-03-28). + * realloc(): When realloc() has to fall back to calling malloc(), size + including overhead was being provided to malloc(), causing a slightly + larger allocation than needed. Noted by initialkjc@yahoo.com + (2017-03-28). + * Fix PTHREAD_MUTEX_INITIALIZER which was not updated with last mutex + changes. From Jussi Kivilinna (2017-03-28). + * STM32 F7: Add stm32 RNG support. This is copied from stm32l4. + Tested on STM32F746ZG board. From Juha Niskanen (2017-03-29). + * STM32 RNG: Fix semaphore initial value and disable priority + inheritance. From Juha Niskanen (2017-03-29). + * Fix an assertion noted by Jussi Kivilinna. This was a consequence of + the recent robust mutex changes. If robust mutexes are selected, + then each mutex that a thread takes is retained in a list in threads + TCB. If the thread exits and that list is not empty, then we know + that the thread exitted while holding mutexes. And, in that case, + each will be marked as inconsistent and the any waiter for the thread + is awakened. For the case of pthread_mutex_trywait(), the mutex was + not being added to the list! while not usually a fatal error, this + was caught by an assertion when pthread_mutex_unlock() was called: + It tried to remove the mutex from the TCB list and it was not there + when, of course, it shoule be. The fix was to add + pthread_mutex_trytake() which does sem_trywait() and if successful, + does correctly add the mutext to the TCB list. This should + eliminated the assertion (2017-03-29). + * 6loWPAN: IEEE802.15.4 MAC driver will need a special form of the + network device structure to manage fragmentation of the large packet + into frames (2017-03-29). + * wireless/ieee802154: Adds MAC character driver structure. + Nonfunctional. From Anthony Merlino (2017-03-29). + * configs/clicker2-STM32: Adds logic to create an 802.15.4 MAC and + register a character driver. From Anthony Merlino (2017-03-29). + * net/local: connect: Fix warning with gcc-arm-none-eabi-5-2016q1. + Using compiler from gcc-arm-none-eabi-5-2016q1 toolchain: + + gcc version 5.3.1 20160307 (release) [ARM/embedded-5-branch revision 234589] (GNU Tools for ARM Embedded Processors) + + gives error: + + local/local_connect.c:188:7: error: '_local_semtake' is static but used in inline function 'local_stream_connect' which is not static [-Werror] + + this is due to compiler enforcing ISO/IEC 9899:1999 6.7.4.3: "An + inline definition of a function with external linkage shall not + contain a definition of a modifiable object with static storage + duration, and shall not contain a reference to an identifier with + internal linkage." Fix by making inlined caller to have internal + linkage as well. From Juha Niskanen (2017-03-30). + * Add entropy pool and strong random number generator. Entropy pool + gathers environmental noise from device drivers, user-space, etc., + and returns good random numbers, suitable for cryptographic use. + Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm + for CSPRNG output. Patch also adds /dev/urandom support for using + entropy pool RNG and new 'getrandom' system call for getting + randomness without file-descriptor usage (thus avoiding + file-descriptor exhaustion attacks). The 'getrandom' interface is + similar as 'getentropy' and 'getrandom' available on OpenBSD and + Linux respectively. From Jussi Kivilinna (2017-03-30). + * Change STM32 tickless to use only one timer. From Konstantin + Berezenko (2017-03-30). + * drivers/sensors: Add driver for ST HTS221 humidity sensor. From Juha + Niskanen (2017-03-30). + * HTS221 driver: Modify to use new interrupt parameter passing hooks + (2017-03-31). + * drivers/sensors: Add driver for ST LPS25H pressure sensor.

Tested + with earlier version of NuttX; with current version checked that it + compiles. Via Juha Niskane (2017-03-31). + * Add user-space networking stack API (usrsock). User-space networking + stack API allows user-space daemon to provide TCP/IP stack + implementation for NuttX network. Main use for this is to allow use + and seamless integration of HW-provided TCP/IP stacks to NuttX. For + example, user-space daemon can translate /dev/usrsock API requests to + HW TCP/IP API requests while rest of the user-space can access + standard socket API, with socket descriptors that can be used with + NuttX system calls.

From Alan Carvalho + de Assis (2017-04-06). + * STM32F7: Serial: add interface to get uart_dev_t by USART number, + stm32_serial_get_uart. From Jussi Kivilinna (2017-04-06). + * STM32F7: Default CONFIG_STM32F7_DMACAPABLE to 'n'. STM32F7 does not + have CCM RAM but DTCM, so this option does not need to enabled. DTCM + RAM is DMA-able through CPU AHBS bus. From Jussi Kivilinna + (2017-04-06). + * STM32F7: Fix UART7 and UART8 IFLOWCONTROL options. From Jussi + Kivilinna (2017-04-06). + * STM32F7: add warning for RXDMA + IFLOWCONTROL combination. + Combination of RXDMA + IFLOWCONTROL does not work as one might + expect. Since RXDMA uses circular DMA-buffer, DMA will always keep + reading new data from USART peripheral even if DMA buffer underruns. + Thus this combination only does following: RTS is asserted on USART + setup and deasserted on shutdown and does not perform actual RTS + flow-control. Data loss can be demonstrated by doing long up_mdelay + inside irq critical section and feeding data to RXDMA+IFLOWCONTROL + UART. From Jussi Kivilinna (2017-04-06). + * sim/sixlowpan: Now supports apps/examples/udpblaster too (2017-04-06). + * SAMV7: Watchdog: fix Forbidden Window Value. According the Datasheet + the WDD Value is the lower bound of a so called Forbidden Window and + to disable this we have to set the WDD Value greater than or equal to + the WDV Value. This seems to be a bug in the datasheet. It looks + like we have to set it to a greater value than the WDV to really + disable this Thing. When triggering the Watchdog faster than the + (very slow) clock source of the Watchdog fires, this Forbidden Window + Feature resets the System if WDD equals to WDV. This Changeset + disables the Forbidden Window by setting the WDD Value to the Maximum + (0xfff) Value possible. From Frank Benkert (2017-04-06). + * RTC: add interface for check if RTC time has been set. New interface + allows checking if RTC time has been set. This allows to application + to detect if RTC has valid time (after reset) or should application + attempt to get real time by other means (for example, by launching + ntpclient or GPS). From Jussi Kivilinna (2017-04-06). + * 6loWPAN: Add network IOCTL support to set the node address + (2017-04-06). + * EFM32 I2C: Fix timeout calculation.

From + Juha Niskanen (2017-05-12). + * syslog: Avoid flushing syslog_stream buffer, if possible, until + lib_vsprintf() completely parses the format.

Suggested by Jussi Kivilinna (2017-05-12). + * syslog: There is yet another place where the output can get split. + That is in syslog_dev_write(): It will break up the stream to insert + a CR before the LF. This can that can be avoid be generating the + CR-LF sequence in the buffer and then detecting and ignoring valid + CR-LF sequences, rather than expecting syslog_dev_write() to insert + the CR in this case. I don't like the idea that syslog_dev_write() + still scans the entire output buffer to expand CR-LF sequence. This + seems really wasteful, especially in this case where we can be sure + that the is no CR or LF without a matching LF or CR.

From + Juha Niskanen (2017-05-15). + * TCP: An RST recevied suring the 3-way handshake requires a little + more clean-up (2017-05-15). + * STM32 CAN: I had the problem that the transmit FIFO size (= actual + elements in FIFO) was slowly increasing over time, and was full after + a few hours. The reason was that the code hit the line + "canerr("ERROR: No available mailbox\n");" in stm32_cansend, so + can_xmit thinks it has sent the packet to the hardware, but actually + has not. Therefore the transmit interrupt never happens which would + call can_txdone, and so the size of the FIFO size does not decrease. + The reason why the code actually hit the mentioned line above, is + because stm32can_txready uses a different (incomplete) condition than + stm32can_send to determine if the mailbox can be used for sending, + and thus can_xmit forwards the packet to stm32can_send. + stm32can_txready considered mailboxes OK for sending if the mailbox + was empty, but did not consider that mailboxes may not yet be used if + the request completed bit is set - stm32can_txinterrupt has to + process these mailboxes first. Note that I have also modified + stm32can_txinterrupt - I removed the if condition, because the CAN + controller retries to send the packet until it succeeds. Also if the + condition would not evaluate to true, can_txdone would not be called + and the FIFO size would not decrease also. From Lederhilger Martin + (2017-05-16). + * drivers/bch: BCH character driver bch_ioctl() always returns -ENOTTY + for DIOC_GETPRIV command. It should returns OK if DIOC_GETPRIV + command succeeds. From EunBong Song (2017-05-16). + * There can be a failure in IOB allocation to some asynchronous + behavior caused by the use of sem_post(). Consider this scenario: + (1) Task A holds an IOB.  There are no further IOBs.  The value of + semcount is zero. Task B calls iob_alloc().  Since there are not + IOBs, it calls sem_wait().  The value of semcount is now -1. (2) + Task A frees the IOB.  iob_free() adds the IOB to the free list and + calls sem_post() this makes Task B ready to run and sets semcount to + zero NOT 1.  There is one IOB in the free list and semcount is zero. + When Task B wakes up it would increment the sem_count back to the + correct value. (3) But an interrupt or another task runs occurs + before Task B executes.  The interrupt or other tak takes the IOB off + of the free list and decrements the semcount.  But since semcount is + then < 0, this causes the assertion because that is an invalid state + in the interrupt handler. So I think that the root cause is that + there the asynchrony between incrementing the semcount. This change + separates the list of IOBs: Currently there is only a free list of + IOBs. The problem, I believe, is because of asynchronies due + sem_post() post cause the semcount and the list content to become out + of sync. This change adds a new 'committed' list: When there is a + task waiting for an IOB, it will go into the committed list rather + than the free list before the semaphore is posted. On the waiting + side, when awakened from the semaphore wait, it will expect to find + its IOB in the committed list, rather than free list. In this way, + the content of the free list and the value of the semaphore count + always remain in sync (2017-05-16). + * stm32_serial: fix freezing serial port. Serial interrupt + enable/disable functions do not disable interrupts and can freeze + device when serial interrupt is received while execution is at those + functions. Trivially triggered with two or more threads write to + regular syslog stream and to emergency stream. In this case, freeze + happens because of mismatch of priv->ie (TXEIE == 0) and actually + enabled interrupts in USART registers (TXEIE == 1), which leads to + unhandled TXE interrupt and causes interrupt storm for USART.

From Alan Carvalho de Assis (2017-05-26). + * configs/pic32mx7mmb: add support for the Pinquino toolchain + (2017-05-27). + * configs/pic32mx7mmb: Repartition files to match newer + configurations. Add support for PROCFS file system. Default is now + Pinguino toolchain. Verify networking (2017-05-27). + * pthread_trylock: Fixes a problem in pthread_trylock() noted by + initialkjc@yahoo.com. When CONFIG_PTHREAD_MUTEX_UNSAFE=y, the + special return value EAGAIN was not being detected due to differences + in reporting of returned values (2017-05-29). + * vfs: fdopen: add missing file stream flags clearing. Clear file + stream structure regardless of config options. Structure clearing is + needed as previous use of stream list entry might leave fs_flags + set. From Harri Luhtala (2017-05-31). + * drivers/input: add Cypress MBR3108 CapSense touch button driver. + From Juha Niskanen (2017-05-31). + * STM32L4: gpio: put back EXTI line source selection. From Juha + Niskanen (2017-05-31). + * mtd/smart: Fix use of uninitialized variable. From Jussi Kivilinna + (2017-05-31). + * drivers/mtd/w25.c: Erase sector only if it is not in erased state. + From Jussi Kivilinna (2017-05-31). + * stm32f7: Add SPI DMA support. From Jussi Kivilinna (2017-05-31). + * drivers/mtd/w25.c: Enable short delay after sector/chip erase. From + Jussi Kivilinna (2017-05-31). + * pthread robust mutexes: Fix memmory trashing problem: the main task + may also use mutexes; need to check thread type before accessing + pthread-specific mutex data structures. Problem noted by Jussi + Kivilinna (2017-05-31). + * STM32L4 RTC: store RTC MAGIC to backup reg, not to address zero. + From Juha Niskanen (2017-06-01). + * drivers/{sensors,usbmisc}: Fix uninitialized I2C frequency. From + Juha Niskanen (2017-06-01). + * mtd/config: Add some error checks for I/O errors. From Juha + Niskanen (2017-06-01). + * pthread mutex: Remove bogus DEBUGASSERT. Problem noted by Jussi + Kivilinna (2017-06-01). + * Tiva SSI: Resolves issue 52 'Copy-Paste error in + tiva_ssibus_initialize()' submitted by Aleksandr Kazantsev + (2017-06-01). + * nucleo-f4x1re User LEDS: Issue #51 reports compilation problems with + stm32_userled.c. Reported by Gappi92 (2017-06-01). + * tools/: Add initialconfig.c so that perhaps in the future we will be + able to use this to generate a new configuration from scratch (rather + than having to derive new configurations from existing + configurations). NOTE: Not yet intregated into the build system + (2017-06-02). + +7.22 2017-xx-xx Gregory Nutt
