Detail:
  This implementation only supports resets - for power-off a more complex implementation will be required (involving talking to the TPS over I2C, AFAIK).
Admin:
  Tested on rev C2 beagleboard


Version 0.14. Tagged as 'OMAP3-0_14'

Detail:
  s/RTC - Implementation of new HAL RTC API. Uses the RTC built into the TWL/TPS companion chip.
  s/Boot - Initialise RTC HALDevice
  s/I2C - Add workaround for apparent hardware limitation of the OMAP I2C controllers; where appropriate multiple iic_transfers will now be merged together into one transfer, to ensure that a start bit is always sent at the start of each transfer
  hdr/omap3530 - Tweak DebugReg and DebugRegByte to allow LR to be output
  Makefile - add s.RTC to list of files. Fix GPADBG definition to not conflict with the 'gpa' folder that one of the makefile fragments creates.
Admin:
  Tested on rev C2 beagleboard


Version 0.13. Tagged as 'OMAP3-0_13'

Detail:
  Makefile, s/Boot, s/I2C, hdr/I2C, hdr/StaticWS - Adds I2C support to the OMAP3 HAL, via both HAL_IIC* and HAL_Video_IICOp.
  s/Interrupts - Fix bug causing incorrect clearing of FIQs
  s/Debug, s/Boot, hdr/omap3530 - Improve debugging code, and add simple FIQ debugger that outputs the PC to the serial port when the beagleboard USER button is pressed
  s/Stubs - Remove old stub functions
Admin:
  Tested on rev C2 beagleboard


Version 0.12. Tagged as 'OMAP3-0_12'

Detail:

Admin:
  Tested on Rev C2 beagleboard


Version 0.11. Tagged as 'OMAP3-0_11'

Detail:
  CPU version is no longer specified in the makefile - it's better to inherit
  it from the build environment now that we actually set it appropriately.
Admin:
  Built and briefly tested.

Version 0.10. Not tagged

Detail:
  Uses suffixed file extensions for compatiblity with both objasm and asasm.
Admin:
  Supplied by Peter Naulls, tested at ROOL

Version 0.10. Not tagged

Detail:
  hdr/StaticWS - Add entries for max porch & sync values, in anticipation of future OMAP revisions increasing the limits from 8/6 bits to 12/8 bits.
  hdr/omap3530 - Add entry for CONTROL_IDCODE register for reading silicon revision
  s/Video - Increase max pixel rate from 65MHz to 75MHz (86.5MHz seems unstable). Add support for different max porch/sync values depending on hardware revision (currently disabled). Make mode change code more robust to try and fix corruption seen when changing mode too many times. Improve HAL_Video_VetMode to check for (HFP+HSW+HBP)*PCD > 8 limitation. Add a bit more debug code.
Admin:
  Tested on rev C2 beagleboard.


Version 0.10. Tagged as 'OMAP3-0_10'

Detail:
  s/Video - Rewritten pointer image update code to correctly read data from RISC OS's 32 pixel wide cursor buffer.
Admin:
  Tested on rev C2 beagleboard. Hourglass now appears properly!

Version 0.07. Tagged as 'OMAP3-0_07'

Detail:
  Makefile - Enable compilation of s.video
  hdr/StaticWS - New workspace entries for video support
  hdr/Video - Typo fix, VENC registers
  s/Boot - Change initialisation order for video support
  s/Debug - Added DebugMemDump routine
  s/RAM - Added code to verify RAM config, to avoid crash if a board looks like a revision C but doesn't have the extra RAM
  s/Stubs - Disable stub video functions
  s/Video - Working video code, beginnings of TV-out code
Admin:
  Tested on rev C2 beagleboard. Video code may only function correctly if kernel is loaded via u-boot.


Version 0.06. Tagged as 'OMAP3-0_06'

Detail:
  s/RAM - Added v4 to register list in RAM clear routines to ensure correct amount of RAM is cleared
Admin:

Detail:
  s/Boot - Fixes for rev C beagleboard. Added GPIO code.
  s/Debug - DebugHALPrint, DebugHALPrintReg routines
  s/PRCM - PRCM_GetFreqSel added
  s/RAM - Fixes for rev C beagleboard. Sped up RAM clear by using more regs.
  s/Top - Fixes for rev C beagleboard
  s/Video - Video code potentially complete, but full of bugs and so still disabled.
  hdr/GPIO - Added GPIO registers
  hdr/omap3530 - Fixes for rev C beagleboard, GPIO, debug macros, QEMU support for new video code
  hdr/SDRC - Typo fix
  hdr/StaticWS - GPIO, pixel rate entries added

Version 0.04. Tagged as 'OMAP3-0_04'

Detail:
  s/Boot - Store some workspace vars used by video code. Disable some debug output.
  s/Interrupts - Update HAL_IRQClear to allow clearing of VSync IRQ
  s/Top - Fix CP15 flags
  s/Video - Implemented majority of video code needed by kernel. Correct code for calculating and programming pixel clocks still required, so code remains disabled by default.
  hdr/PRCM - Correct typo
  hdr/StaticWS - Add video-related workspace entries
  hdr/Video - Add constants for mouse pointer image buffer size
Admin:
  Tested under qemu-omap3 and rev B6 beagleboard.


Version 0.03. Tagged as 'OMAP3-0_03'

Detail:
  Makefile - add s.PRCM to objects
  s/Boot - Call PRCM_SetClocks during HAL_Init. Added (disabled) debugging code.
  s/Interrupts - Updated HAL_IRQSource, HAL_FIQSource to query ARM interrupt state instead of relying on INTC alone to detect whether an interrupt is firing or not.
  s/PRCM - Code to measure system clock frequency, store it for HAL purposes, and notify the OMAP of the frequency in order to ensure correct operation.
  s/Timers - Use measured system clock frequency as the timer frequency instead of hard-coded value. Return correct values from HAL_TimerPeriod.
  s/Top - Added (disabled) debugging code. Updated ARM initialisation to use correct cache cleaning procedure.
  s/Video - Further minor work towards completing video driver.
  hdr/CoPro15ops - Deprecate ARM_flush_* macros
  hdr/PRCM - Add more register addresses
  hdr/StaticWS - Add entried for PowerMan & 32K timer logical addresses, system clock speed
