Detail:
  * Decloak ATA switcher error base

Retagged as 'HdrSrc-2_55'

Version 2.55. Not tagged

Detail:
  * Complete the Cortex-A7 support which was initially added for RPi 2, to
    allow for builds that only target Cortex-A7. Because Cortex-A15 and
    Cortex-A17 CPUs are indistinguishable architecturally from Cortex-A7
    (all are ARMv7VE with VFPv4, Advanced SIMD v2 and hardware integer divide)
    any such platforms are expected to use Machine=CortexA7. Also bear in
    mind that if we ever support multiple cores on big.LITTLE CPUs, execution
    can move between these core types at runtime, making an assembly time
    option to distinguish between them meaningless!
  * Correct Machines All and All32 to include support for VFPv4
  * Decloak the ATA driver SWI chunk
  * Add a global error allocation for use by the ATA subsystem (placed in
    global space because it propagates into the CD stack)

Detail:
  Various allocations relating to SPIDriver and SATAFS made public

Version 2.54. Tagged as 'HdrSrc-2_54'

Version 2.53. Tagged as 'HdrSrc-2_53'

Detail:

  * Extra AUN error
  * Resolved error base clash between AbortRegions and VFPSupport
  * New alias for OS_Byte 221


Version 2.51. Tagged as 'HdrSrc-2_51'

Version 2.40. Tagged as 'HdrSrc-2_40'

Detail:
  Kernel graphics allocations for Jeffrey Lee

Version 2.38. Tagged as 'HdrSrc-2_38'

Detail:
  * Add error block for BASIC module
  * Retire RTCSupport switch in Hdr:Machine.Machine

Version 2.37. Tagged as 'HdrSrc-2_37'

Detail:
  * Retire hdr:FreeWay in favour of hdr:FreewayReg
  * SWI chunk and error base for RTC module

  * Single service calls for boot sequence to inform (primarily ROM) modules
    that system variables have become valid

Version 2.33. Tagged as 'HdrSrc-2_33'

Version 2.29. Tagged as 'HdrSrc-2_29'

Version 2.20. Tagged as 'HdrSrc-2_20'

Also added DrawFiles to indicate key numbers graphically; these should be
considered to update PRM figures 11.1 and 23.3 - 23.5 for post-Archimedes
hardware. These complement the file Hdr:Keyboard.

Version 2.19. Tagged as 'HdrSrc-2_19'

Version 2.17. Tagged as 'HdrSrc-2_17'

Version 2.12. Tagged as 'HdrSrc-2_12'

Version 2.09. Tagged as 'HdrSrc-2_09'

Retagged as 'HdrSrc-2_08'

Version 2.08. Not tagged

Detail:
  * Documented ADFS's and SCSIFS's CMOS use better in Hdr:CMOS.
  * Fixed typo in Hdr:NewErrors that causes asasm to emit a warning.
  * Fixed Hdr:OsBytes so that it doesn't trip up Hdr2H. Also listed hex and
    decimal OS_Byte numbers in comments for ease of reference.
  * Fixed some formatting in Hdr:CMOS and Hdr:NewErrors.

Version 2.05. Tagged as 'HdrSrc-2_05'

Detail:
  The result of an investigation of error number usage in filing systems -
  note that there is still a strong correlation between many of these and the
  filing system error blocks. It seemed wise to record them somewhere.
Admin:
  Tested in a Tungsten ROM build to check for name clashes.

Version 2.03. Tagged as 'HdrSrc-2_03'

Version 1.74. Tagged as 'HdrSrc-1_74'

Version 1.63. Tagged as 'HdrSrc-1_63'

Detail:
  Imported public versions of the registration header files. These have all
  mentions of third-party allocations removed from them, and because these
  are new imports, there's nothing hiding in the revision history either.
Admin:
  Manually inspected for sanity; we'll have to see how well it functions in
  a real build.
