adds DEBUGASSERT for invalid geometry and additional memory debug
logic. Also fixes the dangling pointer on error bug. From Ken
Pettit (2016-07-14).
* arch/arm/src/lpc32xx: Extend LPC43xx EMC code to support SDRAM on a
dynamic memory interface. From Vytautas Lukenskas (2016-07-19).
* arch/srim/src: Add the simulated QSPI (N25Q) flash to the simulation
and modify sim up_spiflash.c to enable it to run with different MTD
drivers based on config options (currently m25p, sst26 and w25).
From Ken Pettit (2016-07-19).
* drivers/pipe: Add support to allocated different sizes for pipe and
fifo buffers. Adds mkfifo2() and pipe2() which are just like mkfifo()
and pipe(), but allow control of the size of the underlying, in-memory
circular buffer . Move pipe() and mkpipe() to nuttx/libc, they are no
longer core OS interfaces. Capability currenty used only by PTY logic
to support, configurable, smaller buffers for PTYs (2016-07-19).
* include/nuttx/drivers: Move driver-related files from include/nuttx
to include/nuttx/drivers. Move driver related prototypes out of
include/nuttx/fs/fs.h and into new include/drivers/drivers.h
(2016-07-20).
* include /nuttx/lib: Move library-related files from include/nuttx to
include/nuttx/lib (2016-07-21).
* drivers/serial/serial.c: Fix a race condition noted by Stefan Kolb.
Between the test if the TX buffer is full and entering a critical
section, bytes may be removed from the TX buffer making the wait
unnecessary. The unnecessary wait is an inefficiency, but not really
a problem. But with USB CDC/ACM it can be a problem because the
entire TX buffer may be emptied when we lose the race. If that
happens that uart_putxmitchar() can hang waiting for data to be
removed from an empty TX buffer (2016-07-22).
* arch/arm/src/stm32 and stm32l4: STM32 F4/L4 RTC ALARM: were enabling
interrupts too early in the power-up sequence, BEFORE the interrupt
system was being initialized (2016-07-23).
* drivers/ioexpander: GPIO driver: Add support for receiving signals
from interrupt pins (2016-07-23).
* drivers/usbdev: USBMSC: Add locks when removing request from queue.
From Wolfgang Reissnegger (2016-07-23).
* drivers/usbdev: USBMSC: Fix reversed logic on waiting for SCSI thread
start. The scsi thread was waiting for the wrong condition. However,
this was masked by the fact that the code creating the scsi thread was
also holding usbmsc_scsi_lock(priv) while initializing data, hence
this lock synchronized the scsi thread start with init completion.
From Wolfgang Reissnegger (2016-07-23).
* arch/arm/src/sam34: SAM3/4 UDP: Fix handling of endpoint RX FIFO
banks. This fixes a race condition where the HW fills a FIFO bank
while the SW is busy, resulting in out of sequence USB packets
(2016-07-23).
