Add support for the STM32F103VET6.
* fs/fs_fdopen.c: Bad check for failure to allocate memory. (Noted
by Ronen Vainish).
* drivers/mmcsd/mmcsd_sdio.c: If the MMC/SD driver were ever
uninitialized then there would be a double release of memory
(Noted by Ronen Vainish).
* fs/mmap/fs_rammap.c: Fix logic error and errno check (contributed
by Kate).
* arch/avr/src: Fixes from AVR32 build errors that have crept in
over the time; incorporated Kconfig for AVR3 (Richard Cochran).
* fs/fat and include/nuttx/fs/fat.h: The FAT file system allocates
memory for sector I/O buffers used to exchange data with the
configured block driver. In some contexts, the block driver may
require DMA-capable memory. If CONFIG_FAT_DMAMEMORY is defined,
then the FAT FS will use platform-provided DMA memory allocators
to allocate the block driver I/O buffers.
* CONFIG_NET_ENC28J60 renamed CONFIG_ENC28J60 to be consistent
in all places.
* drivers/enc28j60.c, include/nuttx/net/enc28j60.h, and
olimex-strp711/src/up_enc28j60.c: No longer passes IRQ number
as a parameter. Instead now passes a call table to manage
ENC28J60 GPIO interrupts. That is because GPIO interrupts are
handled in different ways by different MCUs and some do not
support IRQ numbers for GPIO interrupts.
* mm/mm_gran* and include/nuttx/gran.h: Add a simple granule-
based allocator. The intent of this allocator is to support
simple allocation of DMA I/O buffers. The initial check-in
is code complete but untested (not event built into the
mm/Makefile yet.
* confgs/fire-stm32v2: The board port is basically functional.
Not all features have been verified. The ENC28J60 network
is not yet functional.
* configs/stm3240g-eval/discover: A configuration for testing
the UDP discovery utility. Contributed by Max Holtzberg.
* mm/README.txt: Add a new README file.
* include/nuttx/usb/usb.h, arch/*/src/*usb.c, and arch/*/src/*otg*.c:
Add hooks to to use common, external DMA buffer allocation
implementation.
* net/recvfrom.c: Don't block in recvfrom if (1) read-ahead buffering
is enabled and (2) some data was obtained from read-ahead buffers.
Blocking is a bad idea in that case because there is no timeout!
(submitted by Max Holtzberg).
* configs/stm3240g-eval/xmlrpc: An example configuration for the
Embeddable Lightweight XML-RPC Server at apps/examples/xmlrpc.
See http://www.drdobbs.com/web-development/\
an-embeddable-lightweight-xml-rpc-server/184405364 for more info.
Contributed by Max Holtzberg.
* configs/*/nxwm/defconfig and sched/task_exithook.c: Fixes for
bugs that crept in during recent changes. (Submitted by Max
Holtzberg).
* arch/arm/include/armv7-m/irq.h: Fix a critical bug in irqsave().
It looks like sometimes the compile will re-order some instructions
inapproapriately. This end result is that interrupts will get
stuck off.
* drivers/mtd/w25.c: Beginning of a driver for the Windbond SPI
FLASH family (W25x16, W25x32, and W25x64). The initial check-in
is basically just the SST25 driver with some name changes.
* arch/arm/include/armv7-m/irq.h and arch/arm/src/stm32/stm32_spi.c:
Back out the last change in irq.h. It is (most likely) fine the
way it was. The really interrupt related problem was in stm32_spi.c:
When SPI3 is not enabled, then the irqrestore() falls in the
else clause.
* include/nuttx/compiler.h and other files: Moved always_inline
and noinline __attributes__ here. Also replaced all occurrences
of explicit __atributes__ in other files with definitions from
this header file.
* drivers/mtd/w25.c: The Windbond SPI FLASH W25 FLASH driver is
code complete (but still untested).
* arch/arm/src/stm32/stm32_i2c.c: I2C improvements from Mike Smith.
Unified configuration logic; dynamic timeout calculations;
I2C reset logic to recover from locked devices on the bus.
* configs/*/*/Make.defs, tools/Config.mk, Makefile: Refactor all
common make definitions from the various Make.defs files into
the common tools/Config.mk. Add support for a verbosity options:
Specify V=1 on the make command line in order to see the exact
commands used in the build (Contributed by Richard Cochran).
* drivers/net/enc28j60.c: The ENC28J60 Ethernet driver is
now functional.
* configs/fire-stm32v2: Add support or the fire-stm32v3 board as
well (untested because I do not have a v3 board).
* lib/stdio/lib_sscanf.c: Add %n psuedo-format (from Kate).
* lib/stdio/lib_sscanf.c: There is an issue of handling input
when (1) no fieldwidth is provided and (2) there is no space
seperating the input values. No solutions is in place for this
case now (either space or a fieldwidth must be provided). But
at least some of the bad logic that attempted to handle this
case has been removed (noted by Kate).
* arch/arm/src/stm32/stm32_eth.c: DMA buffer sizes must be an
even multiple of 4, 8, or 16 bytes.
* arch/arm/src/stm32/stm32_idle.c: Fixes STM32F107 DMA issues:
We cannot go into sleep mode while Ethernet is actively DMAing.
* configs/shenzhou/src/up_ssd1289.c: Add infrastructure to support
SSD1289 LCD. Initial checkin is just a clone of the
STM32F4Discovery's FSMC-based LCD interface. The Shenzhou
will need a completely need bit-banging interface; this
initial check-in is only for the framework.
* configs/shenzhou/src/up_ssd1289.c: Bit-banging driver is
code complete.
* configs/shenzhou/src/up_lcd.c: Oops. Shenzhou LCD does not
have an SSD1289 controller. Its an ILI93xx. Ported the
STM3240G-EVAL ILI93xx driver to work on the Shenzhou board.
* configs/shenzhou/nxwm: Added an NxWM configuration for the
Shenzhou board. This is untested on initial check-in. It will
be used to verify the Shenzhou LCD driver (and eventually the
touchscreen driver).
* configs/shenzhou/src/up_touchscreen.c: Add ADS7843E touchscreen
support for the Shenzhou board. The initial check-in is untested
and basically a clone of the the touchscreen support for the SAM-3U.
* tools/cfgparser.c: There are some NxWidget configuration
settings that must be de-quoted.
* arch/arm/src/stm32/Kconfig: There is no SPI4. Some platforms
support SPI3 and some do not (still not clear).
* nuttx/configs/shenzhou: Various fixes to build new NxWM
configuration.
* configs/shenzhou: Oops. The Shenzhou LCD is and SSD1289,
not an ILI93xx.
* configs/shenzhou/src/up_ssd1289.c: The LCD is basically functional
on the Shenzhou board.
* graphics/nxmu: Correct some bad parameter checking that caused
failures when DEBUG was enabled.
* arch/arm/src/armv7-m/nvic.h: Add bit definitions for the AIRCR
register.
* drivers/input/ads7843.c: Need semaphore protection in logic
that samples the position.
* drivers/lcd/ssd1289.c: On some platforms we are unable to
read the device ID -- reason unknown; workaround in place.
* drivers/input/ads7843.c: Add thresholding options and an
option to swap X and Y positions. Fix some logic errors in
the SPI locking/selecting logic.
* arch/arm/src/armv7-m/up_systemreset.c: Add logic to reset
the Cortex-Mx using the AIRCR register. Contributed by Darcy
Gong.
* arch/arm/src/stm32/up_eth.c: Add logic specifically for the
DM9161 PHY. If the DM9161 failed to initialize, then use the
up_sysemreset() logic to reset the MCU. Contributed by Darcy
Gong.
* arch/arm/src/stm32/stm32_gpio.c: Add missing logic to set bit
for SPI3 remap. This fixes the XPT2046 touchscreen driver using
drivers/input/ads7843.c
* configs/shenzhou/src/up_ssd1289.c: Fix naming error in
conditional compilation.
* configs/shenzhou/nxwm/defconfig: Disable reading from the LCD.
This does not work. The hardware and the driver support the
capability, but there is some bug that causes memory corruption.
The work around for now: Just disable reading from the LCD.
* drivers/lcd/ssd1289.c: Add some logic to reduce the amount of
output when CONFIG_DEBUG_LCD is enabled.
* configs/shenzhou/nxwm/defconfig: Bug found and fixed... The
original configuration had too much stuff turned on. Reducing
stack sizes, some features, and buffer sizes made the
configuration reliable (Reading from the LCD is still disabled).
* net/uip/uip_icmpping.c: Fix problem that prevented ping from
going outside of local network. Submitted by Darcy Gong

* Config.in and almost all configurations in configs/ - Changed the
default nuttx path to $(TOPDIR)/../../nuttx
* Misc files. Patch provided by Gerd v. Egidy that solves the following
problems
- binutils 2.21 is not available on the gnu servers anymore, they replaced
it with 2.21.1
- there is some assembler error when compiling gcc for arm, gcc bugzilla
43999
- you can't build nuttx for cortex m3/m4 because of a missing instruction
in the assembler, binutils bugzilla 12296
* Add support for binutils 2.22 and GCC 4.6.3.
* Change name of all tools from xxx-elf to xxx-nuttx-elf
* Added an ARM EABI GCC 4.6.3 configuration (tool name is arm-nuttx-eabi-).

type was not generated by GCC/LD prior to gcc-4.6.3
* R_ARM_REL32 logic is conditionally disabled because it has not been
tested.

* configs/i486-defconfig-4.3.3 - Builds an i486 cross development toolchain
using gcc 4.3.3. Why wouldyou want such a thing? On Linux, of course,
such a thing is not needed because you can use the installed GCC to build
i486 ELF binaries. But that will not work under Cygwin! The Cygwin
toolchain (and probably MinGW), build DOS MZ format executables (i.e.,
.exe files). That is probably not usable for most NuttX targets.
Instead, you should use this i486-nuttx-elf-gcc to generate true ELF binaries
under Cygwin.
