Add OS_ReadSysInfo reason codes 11 (read debug info) & 12 (read extended machine ID)
Jeffrey Lee authored 
Detail:
  OS_ReadSysInfo 10 is left unimplemented since it's a bit fiddly for us.
  OS_ReadSysInfo 11 is compatible with ROL's implementation, exposing HAL_DebugTX and HAL_DebugRX if the HAL provides them.
  See here for 10,11 docs: http://select.riscos.com/prm/core/osreadsysinfo.html
  OS_ReadSysInfo 12 is a new call to return the 'extended machine ID', to allow the HAL to specify the format & validity of the ID.
  If the HAL responds to the new HAL_ExtMachineID call then it's assumed that no old-style machine ID is present. The Kernel will generate an old-style ID using the contents of the extended ID, and use that with OS_ReadSysInfo 2/5.
  New software should use OS_ReadSysInfo 12 in preference to 2/5.
  s/Middle - Updated OS_ReadSysInfo SWI
  s/PMF/osinit - New old-style machine ID initialisation code
  hdr/HALEntries - Added new HAL_ExtMachineID entry

ExportVals 32-bit Kernel.
Old Import from cleaned 360 CD
ARMops Add support for Cortex cache type. Extend ARM_Analyse to, where appropriate, use CPU feature registers to identify CPU capabilities.
Copro15ops Add GET Hdr:CPU.Arch to Kernel copy of Copro15ops, so I don't accidentally break the HAL again
EnvNumbers Import from cleaned 360 CD
HALDevice Add ClearIRQ entry to base HAL device struct, plus a couple of new HAL device IDs & bus types
HALEntries Add OS_ReadSysInfo reason codes 11 (read debug info) & 12 (read extended machine ID)
KernelWS Update OS_IICOp to support multiple IIC buses
KeyWS * HAL can choose to limit amount of screen memory to allocate
ModHand Added new offset field to module header for flags
OSEntries * HAL can choose to limit amount of screen memory to allocate
Options Fix some issues preventing the Cortex kernel from being used on non-Cortex machines
PublicWS Commit of kernel as featured in release 5.00.
RISCOS Clean reimport of hdr.RISCOS (real commit date 2008-03-28 by bavison), without any of the 3rd party allocations.
RTCDevice Migrate 2012 RTC fix to Cortex branch of kernel
Variables Import from cleaned 360 CD
VduExt Added four new VDU variables.
VideoDevice Update VDU HAL device for new OMAPVideo driver, fix MVA-based cache/TLB maintenance ops aborting on ARMv7, add warning to VDU driver about inconsistent state variables during screen mode changes
