OSEntries.h: added a C structure for RISCOS_IICOpV.
GPIODevice.hdr: allocate Pandora and Pi Compute module sub device nos.
HALDevice.hdr/Options.hdr: tabs expanded, capitalised abbreviations.
Not tagged.

Detail:
  hdr/OSEntries, s/HAL, s/Kernel - Add compressed ROM support.
  With the current scheme, a compressed ROM will have everything except the HAL and kernel compressed.
  During the keyboard scan period the kernel will allocate some temporary decompression workspace and call the decompression stub that was appended to the ROM.
  The decompression stub is expected to perform in-place decompression of the ROM. Once decompression is complete the workspace will be freed and the page tables updated to make the ROM image readonly.
  It's the HAL's responsibility to make sure any compressed ROM is located in an area of physically contiguous RAM large enough to hold the uncompressed image.

  Makefile, h/OSEntries - Add C export of hdr/OSEntries
  hdr/HALDevice - Add device ID for Tungsten video device. Convert tabs to spaces for consistency...

Detail:
  A fair number of bus/device types and IDs have been added to the Cortex branch since the branch was created.
  Now that the ClearIRQ entry has also been added, it's about time that the HAL branch was brought up to date.

  Untested, but should be fine.


Version 5.35, 4.79.2.111. Tagged as 'Kernel-5_35-4_79_2_111'

Detail:
  hdr/HALDevice, h/HALDevice - inserted the new 'ClearIRQ' entry point into one of the reserved areas.
  Once the RISC OS-side driver has serviced the device's IRQ the ClearIRQ entry point should be called to allow the HAL device to clear any latched interrupt states in intermediate IRQ controllers (e.g. when using GPIO IRQs on OMAP)
  Since this entry point is new, support for it in existing device drivers isn't guaranteed; HAL device implementations of existing APIs must make sure the use a new major version number to indicate that they require ClearIRQ to be called.
  hdr/HALDevice - added some new bus types to represent the GPMC & L3/L4 interconnects in the OMAP.
  hdr/HALDevice - added ethernet NIC device type & IDs for SMSC9221 & DM9000 NICs

  Tested on rev C2 beagleboard


Version 5.35, 4.79.2.98.2.25. Tagged as 'Kernel-5_35-4_79_2_98_2_25'

Detail:
  * Merged in the change to RISC OS 4.02 kernel that moved the GSTrans
    workspace out of scratch space.
  * Fixed a few bugs in callback postponement, and interrupt holes in
    callback dispatch. See Docs.CallbackChange for full info.
  * Fixed SystemSizeCMOS to SysHeapCMOS - wouldn't build as was.
  * Added an export of a C version of Hdr:HALDevice, based on the Hdr2H
    translation but with an additional struct definition. Required by
    SoundControl 1.00.
  * Added some additional location and ID allocations to Hdr:HALDevice.
    Required by today's HAL and SoundControl.
Admin:
  Partially tested.
