ChangeLog

	  happens, it always looked like there were not open files and a crash
	  could ensue (2015-03-14).
	* fs/fat/fs_fat32.c and fs_fat32.h: Add support for umount2(target,
	  MNT_FORCE) in the FAT file system (2015-03-15).
	* drivers/mmcsd/mmcsd_sdio.c:  Fix some bad logic when file system debug
	  is turned on:  Arguments to syslog were missing so that garbage was
	  being printed (2015-03-15).
	* arch/arm/src/sama5/sam_hsmci.c:  Fix a bug in SAMA5 HSMCI.  The
	  bitfield mask and shift values were reversed resulting in a trashed
	  value for the number of blocks in the BLOCKR register.  This was
	  sufficient to prevent DMA writes from working (2015-03-15).
	* drivers/mtd/at24xx.c, Kconfig, and include/nuttx/fs/ioctl.h:  Add
	  support for (1) the byte-oriented read() method, (2) devices that
	  have extended memory regions, and (3) devices that use 8-bit
	  addressing (2015-03-17).
	* arch/mips/src/mips32/Kconfig, Toolchain.defs, and
	  configs/pic32mz-starterkit/nsh/Make.defs:  Changes that will permit
	  building of the PIC32MZ Start Kit configuration using MPLAB and the
	  XC32 toolchain.  From David Sidrane (2015-03-17).
