Also spotted that USAT can be conditional in the I2C code.

Version 0.12. Tagged as 'OMAP4-0_12'

No longer specified to return _kernel_oserror * implements GraphicsV 14.
Make use of IICStatus defines instead of local copies.
Rename HAL_Video_ to HAL_Video.
Compiles, but not tested.


Version 0.11. Tagged as 'OMAP4-0_11'

Detail:
  SDHCI HAL device created. Also, Entry HAL_UARTDefault added (supports
  OS_SerialOp) and HALDoesVideo switch, previously disabled, is now removed.
Admin:
  Requires SDIODriver 0.04.
  Changes received from Willi Theiss.

Version 0.10. Tagged as 'OMAP4-0_10'

Detail:
  s/UART:
  - HAL_UARTModemControl now uses the correct AND mask; previous code would have always had bit 0 of the mask set.
  - Fixed code in HAL_UARTModemControl that was testing for calls that don't update the register
Admin:
  Builds, but untested
  Identical fix was tested in OMAP3 HAL


Version 0.09. Tagged as 'OMAP4-0_09'

Detail:
  s/USB - For valid controllers, HAL_USBControllerInfo now always returns the correct USB struct size and fills in the controller type. The rest of the buffer is filled in only if the supplied size is large enough. This allows for proper probing of controllers without knowing the required buffer sizes beforehand.
Admin:
  Builds, but untested at runtime
  (Code identical to OMAP3 HAL anyway)


Version 0.08. Tagged as 'OMAP4-0_08'

Submission from Willi Theiss.
Retagged as OMAP4-0_07.

Helps to make tracking changes between OMAP3 and OMAP4 less eye watering, but otherwise functionally the same as 0.06.
