-    * arch/arm/src/stm32/stm32f40xxx_dma.c:  Add DMA support for the STM32 F4
-      family (untested on initial check-in)
-    * arch/arm/src/armv7-m/up_fpu.c:  Add logic for saving an restoring VFP
-      floating point registers on context switches (but also disable the FPU
-      because CodeSourcery doesn't support hard flowing point!)
-    * arch/arm/src/stm32/chip/stm32_eth.h:  Add Ethernet register definitions
-      for the STM32 F4.
-    * arch/arm/srcm/stm32/stm32_eth.c:  Adds an Ethernet driver for the STM32 F4.
-    * arch/arm/srcm/stm32/stm32_dac.c and stm32_adc.c: &quot;Skeleton&quot; files for STM32
-      DAC and ADC drivers.  The actual logic will come later.
-    * arch/arm/srcm/stm32/stm32_eth.c:  There may be a few more lurking bugs, but
-      the STM32 Ethernet driver appears to be fully functional on the STM3240G-EVAL.
-    * arch/arm/srcm/stm32/stm32_eth.c:  Fix an error in clearing abnormal interrupt
-      events.
-    * configs/stm3240g-eval/dhcpd:  Add a DCHP daemon configuration for the
-      STM3240G-EVAL board.

-      STM3240G-EVAL board.
-    * arch/arm/srcm/stm32/stm32_rtc.c, stm32f10xxx_rtc.c, and stm32f40xxx_rtc:
-      Broke out separate drivers to handle the very different RTC implementations
-      in the STM32 F1 and F4 family.
-    * arch/arm/srcm/stm32/stm32f10xxx_rtc.c:  STM32 F4 RTC is functional (12/14/2011)
-    * net/uip-arp.c: Fix compilation issue with CONFIG_NET_ARP_IPIN
-    * include/nuttx/pwm.h and drivers/pwm.c:  Add an interface definition and a
-      &quot;upper half&quot; driver for PWM output.
-    * arch/arm/src/stm32/stm32_pwm.c:  Added a PWM &quot;lower half&quot; driver for the
-      STM32.  The initial check-in is little more than a framework for the driver.
-    * arch/arm/src/stm32/stm32_usbdev.c:  Corrected two CRITICAL errors in the USB
-      device-side driver:  (1) Handling of data overrun condition was wrong.  When
-      there was no further memory to accept further OUT endpoint data, the driver
-      would hang with infinite interrupts; (2) the logic in setting toggle bits
-      was not correct.  However, this driver has functioned for a long time until
-      the particular condition that revealed the bug occurred.  My impression is
-      that this latter bugfix also fixes some STM32 USB performance problems.
-    * configs/hymini-stm32v: A configuration for the HY-Mini STM32v board contributed
-      by Laurent Latil.  Theses changes also include support for the STM32F103VCT6. 
-    * arch/configs/stm3240g-eval/src/up_pwm.c:  Add hooks needed to use the new
-      apps/examples/pwm test of the STM32 PWM  driver.
-    * drivers/mtd/mp25x.c:  Add ability to use different SPI modes and different
-      manufacturers codes.  Fix a error in the wait for not busy (submitted by
-      Mohammad Elwakeel.
-    * arch/arm/src/stm32/stm32_can.c.  Add a low-level STM32 CAN driver. (Initial
-      check is incomplete).  Add loopback support to the driver.
-    * arch/arm/src/stm32/stm32_adc.c.  The ADC is now functional.  A more complete
-      driver would require DMA support.  I have some questions still about the
-      accuracy of the timer-driven sampling.
-    * configs/sure-pic32mx/nsh.  The PIC32 port is (finally) functional.  Add an
-      NSH configuration for the Sure PIC32MX board.
-    * configs/sure-pic32mx/*/defconfig.  Calibrated all PIC32 delay loops.
-    * configs/pcblogic-pic32mx/nsh.  Add an NSH configuration for the PCBLogic
