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).
	* arch/arm/src/stm32/stm32_rtc_lowerhalf.c:  Fix some errors in the
	  STM32 RTC lower-half driver that cause compilation failures.  From
	  shilo.xyz (2015-03-19).
	* arch/arm/src/sama5/chip/sam_tc.h: Fix typos in timer/counter header
	  file.  From Bob Doiron (2015-03-20).
	* configs/olimexino-stm32: Board support for the Olimexino STM32 board
	  from David Sidrane (2015-03-20).
	* PIC32MZ:  Incorporated a set of patches that makes the basic NSH
	  configuration on the PIC32MZ Starter Kit.  From Kristopher Tate
	  (2015-03-22).
	* arch/arm/src/tiva: (1) ADC driver has been re-organized; configuration
	  is now handled in code instead of Kconfig to help reduce bloat and
	  confusion. (2) Timer changed to remove ADC coupling in Kconfig to code
	  and moved configuration up from arch/arm/src/tiva to
	  configs/tm4c123g-launchpad/src. (3) GPIO driver needed small fixes in
	  the configuration routines and discovered false-positive bugs in
	  interrupt testing: interrupts are now verified to actually be working
	  reliably. (4) Attempt to apply some consistency in the tiva arch/
	  level's interface to the config/board/ level driver configuration.
	  From Calvin Maguranis (2015-03-23).
	* arch/mips/src/pic32mz: Various fixes for Ethernet support.  Still
	  not fully functional.  From Kristopher Tate (2015-030-29).
	* arch/arm/src/armv7-m:  Add configuration option and logic to support
	  the D-Cache in write-through mode (2015-03-29).
	* arch/arm/src/stm32/Kconfig, stm32_lse.c, stm32_lsi.c, stm32_rtc.c/.h,
	  stm32_rtcc.c, stm32_rtcounter.c, and stm32f*_rcc.c: The
	  STM32F4Discovery board doesn't come with a Low speed external
	  oscillator so the default LSE source for the RTC doesn't work. In
	  stm32_rtcc.c the up_rtcinitialize() logic doesn't work with the LSI.
	  The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call
	  that rightfully enables the lsi clock; but the next times, when the
	  rtc is already setup, the rtc_resume() call does NOT start the lsi
	  clock! The right place to put LSE/LSI initialisation is inside
	  stm32_stdclockconfig() in stm32fxxxxx_rcc.c.  Doing this I checked
	  the possible uses of the LSI and the LSE sources: the LSI can be used
	  for RTC and/or the IWDG, while the LSE only for the RTC (and to output
	  the MCO1 pin). This change is not verifed for any other platforms.
	  From Leo Aloe3132
	* Rename arch_nshinitialize() to board_app_initialize() (2015-03-30).
	* ./*.mk, configs/.gitignore, Makefile, boardctl.c, include/nuttx/fs/ioctl,
	  include/sys/boardctl.h, syscall.h, and syscall/:  Add a new non-
	  standard OS interface called boardctl().  This is similar to a driver
	  IOCTL call.  But this is an IOCTL call directly on the board logic.
	  This function will eventually replace all of the ad hoc OS interfaces
	  that are current used to perform application specific initialization
	  and application driver test configuration.  It essentially formalizes
	  and institutionalizes these rogue interface in to at least a single
	  crazy call (2015-03-31).
	* configs/: Modify all configurations:  Make sure that
	  CONFIG_LIB_BOARDCTL=y appears wherever CONFIG_NSH_ARCHINIT=y appears.
	  Remove support for CONFIG_NSH_ARCHMAC.  It is not used and there are
	  better ways to do that operation (2015-03-31).
	* configs/Kconfig, boardctl.c, all touchscreen driver setup functions,
	  include/board.h, include/sys/boardctl.h, and
	  include/nuttx/input/touchscreen.h: arch_tcinitialize() and
	  arch_tcunitinitialize() renamed to board_tsc_setup() and
	  board_tsc_teardown().  These are not long called directly by
	  applications but only indirectly throught the crappy boardctl() OS
	  interface (2015-03-31).
	* configs/Kconfig, boardctl.c, include/nuttx/board.h, include/sys/boardctl.h,
	  and several ADC files in configs/<board>/src/:  Rename adc_devinit() to
	  board_adc_setup().  Add support to the boardctl() interface so that it
	  can call board_adc_setup() on behalf of an application.  Make sure that
	  the proper features are enabled in the defconfig files that have
	  CONFIG_EXAMPLES_ADC=y (2015-03-31).
	* configs/*/defconfig:  Make sure that all defconfig files that require
	  external graphics intiialization also enable the correct boarctl()
	  settings (2015-03-31).
	* include/nuttx/board.h, include/sys/boardctl.h, nuttx/configs/Kconfig and
	  boardctl.c, and board configurations and PWM implementations: Rename
	  pwm_devinit() to board_pwm_setup().  Add CONFIG_BOARDCTL_PWMTEST that
	  will enable calling board_pwm_setup() from boardctl().  In all
	  configurations that enable the apps/examples/pwm test, make sure that
	  boardctl() support is properly enabled (2015-03-31).
	* Move include/nuttx/timer.h, rtc.h and watchdog.h to include/nuttx/timers/.
	  (2015-04-01).
	* drivers/timer/cs2100-cp.c and include/nuttx/timers/cs2100-cp.h: Add a
	  very basic driver for the CS2100-CP Fractional-N Multipler chip (2015-04-02).
	* configs/, graphics/, include/nuttx:  More renaming: up_lcdinitialize->board_lcd_initialize,
	  up_lcdgetdev->board_lcd_getdev, up_lcduninitialize->board_lcd_uninitialize
	  (2015-04-04).
	* include/nuttx/nx, libnx/nx, libnx/nxtk: Add a new 'capped' parameter to
	  nx_drawline(), nxtk_drawlinetoolbar(), and nxtk_drawlinewindow()
	  (2015-04-05).
	* libnx/nx/nx_drawline.c, libnx/nxtk/nxtk_drawlinetoolbar.c and
	  nxtk_drawlinewindow.c: Implement line caps by drawing a file circle at
	  the each endpoint of a line with a radius equal to half of the width
	  of the line (2015-04-05).
	* include/time.h, nuttx/time.h, libc/time/lib_dayofweek.c and
	  lib_gmtimer.c: Implements CONFIG_TIME_EXTENDED as we discussed
	  relative to providing the last 3 members of the tm struct and support
	  for filling them in and even using the wday in the STM32 RTC. From
	  David Sidrane.
