ChangeLog

	  AT25 Serial FLASH are now supported by default in the NSH configuration
	  (2014-3-14).
	* sched/nanosleep.c:  Fix a missing call to re-enable interrupts.  From
	  Jason Jiang (2014-3-15).

7.2 2014-xx-xx Gregory Nutt <gnutt@nuttx.org>

	* arch/arm/src/sam34/sam_udp.c and .h:  Add a USB full speed device
	  driver (UDP) for the SAM4E (2014-3-17).
	* Documentation/NuttxPortingGuide.html:  Typo fixes from Vijay Kumar
	  (2014-3-18).
	* arch/arm/Kconfig:  Improved documentation of the use of the
	  BASEPRI register from Vijay Kumar (2014-3-19).
	* include/nuttx/i2c.h:  More typo fixes from Vijay Kumar (2014-3-19).
	* arch/Kconfig and *_assert.h:  Add a configuration option to enable
	  dumping of the USB trace buffer on assertion (2014-3-19).
	* drivers/usbdev/Kconfig, arch/arm/src/sam34/Kconfig, and
	  drivers/usbdev/usbmsc_scsi.c:  If DCD can support queuing of stall
	  requests, then the USB MSC stall work around delays are not necessary
	  (2014-3-20).
	* net/netdev_findbyaddr.c:  Skip network devices that are in the
	  "down" state.  It does not make sense to consider an address match
	  with a "down" device.  From Brennan Ashton (2014-3-20).
	* configs/sam4e-ek/usbnsh:  Add a NSH configuration that uses the
	  NSH console (2014-3-22).
	* arch/arm/src/stm32/stm32_eth.c:  Add IGMP hashing support.  From
	  Manuel Stühn (2014-3-24).
	* net/netdev_ioctl.c and uip/uip_input.c:  IGMP-related bug fixes
	  from Manuel Stühn (2014-3-24).
	* arch/arm/src/sam34:  Add missing HSCMI configuration settings to
	  Kconfig; update naming to include SAM34_ (2014-3-24).
	* configs/sam4e-ek/include/board.h:  Update HSMCI timing to use the
	  CLKODD bit (2014-3-24).
	* drivers/include/mtd/Kconfig, sector512.c, and include/nuttx/mtd/mtd.h:
	  Add a new MTD driver that can be used to contain another driver and
	  force its apparent sector size to be 512 bytes (2014-3-24).
	* arch/arm/src/sam34/sam_lowputc.c sam_serial.c:  Fix a mysterious
	  multithreading bug that can log up the serial port (2014-3-14).
	* drivers/usbdev/Kconfig, usbmsc.c, usbmsc.h, and usbmsc_scsi.c:
	  Redesign threading module used with the USB MSC driver.  It was using
	  pthreads before and these were changed to a kernel thread.  The reason
	  for this has to do with task grouping:  A pthread is a memory of the
	  group of the task that started it.  A kernel thread is independent of
	  the task that started in (other than knowing it as the parent).  This
	  allows me to remove so kludge logic to "deparent" the pthread on
	  startup (2014-3-25).
	* tools/astyle.sh:  A code formatting tool from Lorenz Meier.  This
	  tool should do a better job than the old tools/indent.sh tool
	(2014-3-26).
	* arch/arm/src/sam_hsmci.c and sam_spi.c:  Add support to invalidate
	  cached memory if the CMCC is enabled (not yet tested, 2014-3-26).
	* arch/arm/src/sam_spi.c:  Add logic to handle SPI word widths > 8
	  (also untested on initial checkin, 2014-3-26).
	* configs/sam4e-ek:  All configurations updated to run with 120MHz
	  CPU speed and with the CMCC enabled.  Calibrated delay loop
	  (2014-3-26).
