spectacular new OS_Memory reason codes 13 map permanent I/O space, return logical address 14 access temporary physical mapping 15 release temporary physical mapping

DA creation and I/O space creation now avoid collision if address
space fills

Detail:
  Maths was wrong.  The returned baud rate is the crystal frequency divided
by the divisor.

Admin:
  Assembles, not tested.

Version 5.35, 4.79.2.20. Tagged as 'Kernel-5_35-4_79_2_20'

An attempt to do NVMemory by using part of the Flash that the OS is sitting
in for Customer L. Programming algorithm works, but I'm not confident that the
Kernel does the right thing yet.

Version 5.35, 4.79.2.17. Tagged as 'Kernel-5_35-4_79_2_17'

Detail:
  HAL entries have been entered for the Customer L UART (very much like the ARM
PrimeCell, rather than the 16550).
Admin:
  It builds.

  (highlight level of testing that has taken place)
  (bugfix number if appropriate)

kernel now attempts to substitute video mode numbers in face of h/w with limited bits-per-pixel support (not tested yet)

HAL_API document added - early draft only, of interest to those
writing or modifying HALs for new h/w
ARMop_API document added - early draft only, of interest only
to those modifying kernel to support new ARM cores
*** polite comments on HAL_API welcome ***

Version 5.35, 4.79.2.15. Tagged as 'Kernel-5_35-4_79_2_15'

First attempt at ARM9 support, and general clean-up of old ARM-specific code, now using vectored ARMops.

Not tested.

Version 5.35, 4.79.2.14. Tagged as 'Kernel-5_35-4_79_2_14'

Check-in of the few last-minute changes for the Customer L demo. Nothing exciting, apart from an extended touchscreen API.

Version 5.35, 4.79.2.12. Tagged as 'Kernel-5_35-4_79_2_12'

more use of ARMops in page manipulation, change register usage of ARmops tested by kernel boot to star prompt only

Version 5.35, 4.79.2.11. Tagged as 'Kernel-5_35-4_79_2_11'

Detail:
  It's actually in a section removed conditionally for the HAL but it
    does keep the HAL branch up to date.

Version 5.35, 4.79.2.10. Tagged as 'Kernel-5_35-4_79_2_10'

More stuff. Up to the desktop now; cache on, working keyboard. Some source restructuring to start to make splitting it up into several object files more feasible.

Version 5.35, 4.79.2.9. Tagged as 'Kernel-5_35-4_79_2_9'

Imported from Kernel 5.36.

It says "Abort on data transfer".

Detail:
  Added the HAL NVRAM entries.
  Modified i2cutils to use the HAL entries for NVRAM and behave sensibly if the HAL reports that there is no NVRAM, in which case there must be a forced reset_cmos call so that the cache gets set up sensibly.
Admin:
  Tested under the RPC emulator and appears to be working correctly, although some calls to IIC are still being made in the no nvram case.

Version 5.35, 4.79.2.7. Tagged as 'Kernel-5_35-4_79_2_7'

mjs macros switch on HAL for calling video code in HAL/pseudo HAL cases vduhint code even more almost ready to move to HAL

Version 5.35, 4.79.2.5. Tagged as 'Kernel-5_35-4_79_2_5'

further kernel/HAL split work in video area almost-HAL code for VIDC20/IOMD in vdu.vduhint, now almost divorced from kernel workspace tested briefly in Ursula desktop environment

Version 5.35, 4.79.2.4. Tagged as 'Kernel-5_35-4_79_2_4'

partial video changes for kernel/HAL split near-HAL code for VIDC/IOMD in vdu.vduhint briefly tested in Ursula desktop build still some kernel workspace dependency in near-HAL code
