Version 5.35, 4.79.2.175. Tagged as 'Kernel-5_35-4_79_2_175'

Variously the call to TranslateError was either followed (outside the switch) by an unnecessary SETV, or missing SETV for the non international case.
Added DMA controller HAL device for IOMD.

Version 5.35, 4.79.2.174. Tagged as 'Kernel-5_35-4_79_2_174'

Detail:
  s/HAL, s/NewReset - Moved IIC initialisation to just after timer initialisation, and crucially, before keyboard scan initialisation. This makes things a lot easier for the HAL if it wants to use IIC during the keyboard scan (previously IIC would be enabled inbetween HAL_KbdScanSetup and the first call to HAL_KbdScan)
  hdr/HALDevice - Added a device ID for the Pandora audio controller
Admin:
  Tested on Pandora


Version 5.35, 4.79.2.168. Tagged as 'Kernel-5_35-4_79_2_168'

Version 5.35, 4.79.2.166. Tagged as 'Kernel-5_35-4_79_2_166'

Fix addresses sent to GraphicsV_SetDMAAddress when external framestore in use. Add ID for BCM2835 VDU HAL device.

Detail:
  hdr/KernelWS, s/vdu/vdudriver, s/vdu/vduwrch - Fixed wrong addresses being sent to GraphicsV_SetDMAAddress when an external framestore is in use. Previously VideoPhysAddr was being treated as if it was the base of screen memory, but that's only the case if an internal framestore is in use. Since VideoPhysAddr is part of PhysRamTable it's not possible to change it to point to an external framestore, so a new workspace variable, TrueVideoPhysAddr, is used instead.
  hdr/HALDevice - Added device ID for BCM2835 VDU device

Admin:

Version 5.35, 4.79.2.145. Tagged as 'Kernel-5_35-4_79_2_145'

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.
  More info here: http://www.riscosopen.org/wiki/documentation/show/Compressed%20ROMs
  Makefile, h/OSEntries - Add C export of hdr/OSEntries
  hdr/HALDevice - Add device ID for Tungsten video device. Convert tabs to spaces for consistency.
  hdr/HALEntries, s/NewReset - Moved KbdFlag_* definitions to hdr/HALEntries so HALs can use them in their keyboard scan code
  s/ArthurSWIs, S/HAL, s/HeapSort, s/Kernel, s/MemInfo, s/Middle, s/NewIRQs, s/TickEvents, s/vdu/vdugrafb - Make use of BLX, BFI and long multiplies if the CPU supports them. Don't support SWI calls from thumb mode if the CPU doesn't support thumb.
  s/HAL - Made the LDMIA in Init_MapInRAM more sensible (register order was backwards). The old code did work, but wasn't doing what the comments described. Removed unused/unfinished HAL_Write0 function. Improve RISCOS_LogToPhys to check L1PT for any section mappings if the logical_to_physical call fails
  s/ModHand - Save one instruction by using ADR instead of MOV+ADD to compute lr
  s/NewReset, s/PMF/key - Pass L1PT to HAL_Reset to allow machines without hardware reset (e.g. IOMD) to perform resets by manually disabling the MMU and restarting the ROM
  s/vdu/vdudriver, s/vdu/vdugrafv - Use GVEntry macro borrowed from NVidia module for setting up the GraphicsV jump table. Make GraphicsV_ReadPaletteEntry call HAL_Video_ReadPaletteEntry if left unclaimed. Fixup GV_Render to only call HAL_Video_Render if the HAL call is implemented.
Admin:
  Tested with OMAP3, IOMD & Tungsten ROMs/softloads.

Version 5.35, 4.79.2.98.2.50. Tagged as 'Kernel-5_35-4_79_2_98_2_50'

Detail:
  hdr/HALDevice - Device types & IDs for CPU clock generator and GPIO interface
  hdr/HALEntries - HAL_ExtMachineID entry (but not used by this kernel yet)
Admin:
  Tungsten ROM built OK, but untested at runtime.


Version 5.35, 4.79.2.116. Tagged as 'Kernel-5_35-4_79_2_116'

Detail:
  hdr/HALDevice - Added GPIO device type in the Comms group, and an ID for a generic OMAP3 GPIO device
  hdr/GPIODevice - Definition of GPIO device structure. Currently only used to store the type and revision of the main board, so the GPIO manager module can tailor its features appropriately.
  Makefile - Export hdr/GPIODevice
Admin:
  Tested on rev A2 BB-xM


Version 5.35, 4.79.2.98.2.42. Tagged as 'Kernel-5_35-4_79_2_98_2_42'

Version 5.35, 4.79.2.98.2.36. Tagged as 'Kernel-5_35-4_79_2_98_2_36'

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.
Admin:
  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
Admin:
  Tested on rev C2 beagleboard

Version 5.35, 4.79.2.98.2.16. Tagged as 'Kernel-5_35-4_79_2_98_2_16'

Detail:
  HAL kernels (on the Cortex branch at least) now support HALDevice-based RTCs. If the kernels own RTC code is disabled or fails to detect an RTC, then after HAL_InitDevices is called the HALDevice list will be scanned for any HAL-resident RTC devices.
  Additionally, the RTCSupport flag (in Hdr:Machine.Machine), which was previously TRUE for all HAL kernels, can now be set to FALSE in HAL kernels to disable the kernels own IIC RTC code. This allows the unwanted legacy RTC code to be disabled for machines which are known to use HAL RTCs instead.
  hdr/RTCDevice - new header describing data structures used for HAL RTC device
  hdr/HALDevice - added RTCDevice device type, IIC serial bus type
  hdr/KernelWS - upgraded RTCFitted from a 1 byte field to 4 byte. It now stores either a null value (for no RTC), a value <2048 for an IIC RTC address, or a value >= 2048 for a RTCDevice ptr
  Makefile - added header export of hdr/RTCDevice
  s/GetAll - include hdr/RTCDevice
  s/NewReset - initialise HAL RTC after HAL_InitDevices if required
  s/PMF/i2cutils, s/PMF/osinit, s/PMF/osword - modifications to allow use of HAL RTC (and disallow use of builtin IIC RTC)
Admin:
  Tested on rev C2 beagleboard


Version 5.35, 4.79.2.98.2.11. Tagged as 'Kernel-5_35-4_79_2_98_2_11'

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.

service call allocations have been confirmed.

Version 5.35, 4.79.2.54. Tagged as 'Kernel-5_35-4_79_2_54'

Detail:
  * Rejigged documented meaning of device "Location" field so that we can
    fit full PCI locations in.
  * Defined lots of device "Type" values in Hdr:HALDevice.
  * Removed obsolete DMA-related HAL entries in Hdr:HALEntries (no longer
    required by DMAManager 0_15-4_4_2_6, no longer provided by Tungsten HAL
    0.07).
  * OS_Hardware 2 and 3 actually work now.
  * Changed OS_Hardware 4 to take a maximum major version number to match.
  * HAL workspace is now USR mode readable.
  * Service calls issued after module initialisation/finalisation (see
    Docs.ModPostServ).
