Fix dodgy mode changes on Raspberry Pi. Fix crash when switching to a driver which uses DA 2 if DA 2 isn't already large enough.

Detail:
  s/vdu/vdudriver:
  - Fix bug in ModeChangeSub which caused the VariableFramestore flag to be ignored, resulting in unreliable mode changes on the Raspberry Pi.
  - Changed InitialiseMode to reset a few more variables when preparing to use a driver which uses DA 2. Without this the screen DA handler will likely crash when attempting to resize the DA for the initial mode change.

Detail:
  s/MemInfo - Fix OS_Memory 0 physical-to-logical conversion returning bad addresses for most cases due to R5 being modified by physical_to_ppn (bug introduced in revision 4.4.2.20)
  s/vdu/vdudriver - Fix some VDU driver variables not being initialised correctly when switching GraphicsV driver

  s/vdu/vduswis - Fix abort when OS_ScreenMode 11 is passed a bad driver number
Admin:
  Tested on Raspberry Pi
  There still seems to be a bug lurking somewhere when switching to a GraphicsV driver that uses DA2; the system will crash horribly unless DA2 is already a suitable size for the initial mode change

Version 5.35, 4.79.2.204. Tagged as 'Kernel-5_35-4_79_2_204'

Detail:
  This set of changes:
  * Adds basic support for multiple GraphicsV drivers, by way of some new OS_ScreenMode reason codes for registering/deregistering, selecting and enumerating drivers (11, 64-68)
  * Tidies up handling of HAL video calls so that the HAL calls will be transformed into a bona fide GraphicsV driver if they're implemented
  * Changes handling of 16bpp gamma table entries so that they're sent to GraphicsV in a generic form instead of in a VIDC-specific form
  * Adds a new GraphicsV call and defines new VIDC list items to allow GraphicsV drivers to utilise the new pixel formats
  File changes:
  * h/VIDCList, hdr/VIDCList, Makefile - Add new header export containing VIDC list type 3 definitions, to avoid repeated definitions in other components
  * Resources/UK/Messages - Add new GraphicsV/OS_ScreenMode error strings and some missing processor type strings
  * hdr/KernelWS - Clean up some pre-GraphicsV definitions, and add new workspace locations for storing the current GraphicsV driver number and the driver list
  * hdr/Options - Remove obsolete InverseTextTransparency option
  * hdr/VduExt - Add VDU variable 192 for storing GraphicsV driver number (same as ROL's VideoV driver number). Remove old 'Flag_*' mode flag definitions (use new 'ModeFlag_*' defintions instead). Add new OS_ScreenMode reason codes.
  * s/ARM600, s/VMSAv6, s/vdu/vdu23, s/vdu/vdugrafa, s/vdu/vdugrafd, s/vdu/vdupalxx, s/vdu/vdupointer, s/vdu/vduwrch - Strip out pre-GraphicsV code. Update GraphicsV code to use correct driver number.
  * s/ArthurSWIs - Pass the default GraphicsV claimant the VduDriverWorkSpace instead of ZeroPage
  * s/Getall - Add Hdr:VIDCList and s/vdu/VduGrafHAL to list of GETs
  * s/NewIRQs - Remove HAL VSync IRQ initialisation, is now handled by grafvhal. Remove old HAL VsyncIRQ entry point, all VSyncs are now handled by VsyncIRQ_ExtEntry.
  * s/PMF/osbyte - Stop OS_Byte 19 waiting forever if no video driver is active
  * s/PMF/osinit - Remove HAL VSync IRQ initialisation, is now handled by grafvhal
  * s/vdu/vducursoft - Use new workspace variable names and flag names
  * s/vdu/vdudecl - Remove old HALDAG_* definitions, GVDAG_* definitions are used instead. Add definition of the per-driver workspace structure and flags.
  * s/vdu/vdudriver - Remove pre-GraphicsV code. Update InitialiseMode to check for and initialise a HAL driver. Use cached driver features word in a few places instead of calling GraphicsV each time. Update PalIndexTable to disable VIDC mangling of 16bpp gamma tables.
  * s/vdu/vdugrafv, s/vdu/vdugrafhal - HAL<->GraphicsV code split off into its own file (vdugrafhal). Default GraphicsV claimant now only deals with VSync events for the active driver.
  * s/vdu/vdumodes - Get rid of old VIDC List type 3 definiton; now in hdr/VIDCList
  * s/vdu/vduswis - Added OS_ScreenMode reason codes 11 and 64-68 for registering, deregistering, selecting and enumerating GraphicsV drivers. Update mode set code to not bother checking if the driver supports the pixel format; instead we assume that the driver's vet mode call will do the check for us.

Tip offs from eagle eyed Tim Baldwin.

Version 5.35, 4.79.2.201. Tagged as 'Kernel-5_35-4_79_2_201'

There's an exit case from CheckYear which skips the actual clock read, so add an explicit call to RTCToRealTime for that case (cf. OS_ResyncTime).
Remove use of ARMv2 era MULTIPLY macro, just use MUL.
Tested on IOMD with a HAL RTC.

Version 5.35, 4.79.2.197. Tagged as 'Kernel-5_35-4_79_2_197'

No longer returns a RISC OS specific error block to the HAL, instead uses a platform agnostic IICStatus value.

Version 5.35, 4.79.2.195. Tagged as 'Kernel-5_35-4_79_2_195'

Add support for the new RISC OS 5 style sprite mode word. Add partial support for alpha channel sprite masks. Implement OS_ScreenMode reasons 13-15

Detail:
  ECFShift/ECFYOffset:
  - hdr/PublicWS - Add ECFShift and ECFYOffset to list of public exports (SpriteExtend was using hardcoded values). Rearrange exports so that VduWorkspace exports are now labelled as such.
  - hdr/KernelWS - Make sure ECFShift & ECFYOffset match their exported locations
  - hdr/OSRSI6, s/Middle - Add OS_ReadSysInfo 6 items 83 & 84, for reading ECFYOffset and ECFShift locations
  Mode flags/VDU variables:
  - Makefile - Add hdr/VduExt to the C header exports
  - hdr/VduExt - Get rid of NotRVVTBarWobblyBits macro and defined VDU variables manually so that Hdr2H will handle them. Begin replacing overly generic 'Flag_*' mode flag definitions with 'ModeFlag_*' instead. Define new flags as required by the new screen/sprite modes. Add OS_ScreenMode reason codes and mode selector format (from s.vdu.vdudecl)
  - NewModes/NEWF2, NewModes/OldPSSrc, NewModes/PSSrc, s.vdu.vdu23, s.vdu.vducursoft, s.vdu.vdudriver, s.vdu.vdugrafg, s.vdu.vdugrafj, s.vdu.vdugrafl, s.vdu.vdumodes, s.vdu.vdupal10, s.vdu.vdupal20, s.vdu.vdupalette, s.vdu.vdupalxx, s.vdu.vduwrch - Renaming Flag_* to ModeFlag_*
  - s.vdu.vdudecl - Remove OS_ScreenMode reason codes & mode selector format definitions; these are now in hdr/VduExt. Flag_* -> ModeFlag_* renaming.
  - s.vdu.vdupalxx - Apply a greyscale palette in PV_SetDefaultPalette if the greyscale mode flag is set
  New sprite types:
  - s.vdu.vdudriver - Extend GenerateModeSelectorVars to deal with the wide mask flag, 64K sprites, and the new RISC OS 5 sprite mode word format.
  - s.vdu.vdugrafdec - Store more information about the sprite in the SprReadNColour ... SprLog2BPC block.
  - s.vdu.vdugrafg - Update SpriteVecHandler to be able to detect whether RISC OS 5 format sprites are allowed palettes. Update SetupSprModeData to store the extra sprite info that's defined in vdugrafdec. Update PutSprite to fault any sprites with wide masks - SpriteExtend must be used for that (once implemented!)
  - s.vdu.vdugrafh - Update WritePixelColour to avoid temporary poking of NColour VDU variable for 8bpp sprites. Correctly replicate data when writing to RISC OS 5 format sprites. Update ReadPixelMask, WritePixelMask, SpriteMaskAddr, GetMaskspWidth to deal with wide masks. Delete obsolete bounce_new_format_masks routine.
  - s.vdu.vdugrafi - Comment updated to reflect new reality
  - s.vdu.vdugrafj - Get rid of unused code block in CreateHeader/PostCreateHeader. Update SanitizeSGetMode to generate RISC OS 5 style sprite mode words where applicable. Update DecideMaskSize to rely on GetMaskspWidth for calculating mask width.
  - s.vdu.vdugrafl - Update SwitchOutputToSprite/SwitchOutputToMask to deal with the new sprite formats. Allow PushModeInfoAnyMonitor to fail.
  - s.vdu.vduswis - Extended OS_ReadModeVariable to cope with new sprite types
  Misc:
  - s.vdu.vdudriver - Fixed bug with VIDCList copying where any -1 value in the structure would terminate the copy, instead of only -1 as a control item number
  - s.vdu.vduswis - Implemented OS_ScreenMode 13 (Mode string to specifier), 14 (mode specifier to string), and 15 (set mode by string). Mostly as per ROL's specs, but minus support for teletext attributes, and plus support for new RISC OS 5 attributes (L... layout specifier, 4096 & 24bpp packed modes, etc.)
  - s.vdu.vduwrch - Pick correct default text colours for the new modes

Version 5.35, 4.79.2.190. Tagged as 'Kernel-5_35-4_79_2_190'

The StrongARM TRM (and hints from ARM600.s revision 4.3.2.2) show that the StrongARM will only do burst writes to memory marked as C=1 B=1, but by default RISCOS_AccessPhysicalAddress only allows bufferable.
So, checking for StrongARM first, two extra snippets are enabled - first mark as C=1 B=1, then afterwards clean the cache before moving onto the next 1MB.

On a StrongARM Kinetic these burst writes improve the RAM clear from ~60ms per MB to 40ms per MB. For a 256MB SODIMM that's over 5s knocked off the boot time.
Other memory configurations will be similarly improved, though 256MB is of course the maximum the motherboard can hold.

Tested in ROM on a Risc PC with StrongARM and ARM710.

Version 5.35, 4.79.2.189. Tagged as 'Kernel-5_35-4_79_2_189'

Detail:
  s/Middle - If the HAL provides an extended machine ID, make sure OS_ReadSysInfo 4 doesn't return a MAC address. This is because the old-style machine ID which the MAC is extracted from will be completely synthetic and is so known not to contain a MAC (even if it may look like it does)

Version 5.35, 4.79.2.187. Tagged as 'Kernel-5_35-4_79_2_187'

Detail:
  Briefly, this set of changes:
  * Adjusts PhysRamTable so that it retains the flags passed in by the HAL from OS_AddRAM (by storing them in the lower 12 bits of the size field)
  * Sorts the non-VRAM entries of PhysRamTable by speed and DMA capability, to ensure optimal memory allocation during OS startup.
  * Adjust the initial memory allocation logic to allow the cursor/sound chunk and HAL noncacheable workspace to come from DMA capable memory
  * Extends OS_Memory 12 to accept a 'must be DMA capable' flag in bit 8 of R0. This is the same as available in ROL's OS.
  * Extends OS_DynamicArea 0 to allow the creation of dynamic areas that automatically allocate from DMA capable memory. In ROL's OS this was done by setting bit 12 of R4, but we're using bits 12-14 for specifying the cache policy, so instead bit 15 is used.
  * Fixes OS_ReadSysInfo 6 to return the correct DevicesEnd value now that the IRQ/device limit is computed at runtime
  File changes:
  * hdr/OSEntries - Add definitions of the various flags passed to OS_AddRAM by the HAL. Add a new flag, NoDMA, for memory which can't be used for DMA.
  * hdr/KernelWS - Tidy PhysRamTable definition a bit by removing all the DRAM bank definitions except the first - this makes it easier to search for code which is interacting with the table. Remove VRAMFlags, it's redundant now that the flags are kept in the table. Add DMA allocation info to InitWs.
  * s/AMBControl/memmap - Updated to mask out the flags from PhysRamTable when reading RAM block sizes.
  * s/ARM600 - Strip out a lot of IOMD specific pre-HAL code.
  * s/ChangeDyn - Updated to cope with the flags stored in PhysRamTable. Implement support for DMA-capable dynamic areas. Rewrite InitDynamicAreas to insert pages into the free pool in the right order so that the fastest memory will be taken from it first.
  * s/GetAll, s/Middle - Fix OS_ReadSysInfo 6 to return the correct HAL-specific DevicesEnd value
  * s/HAL - Significant rework of initial RAM allocation code to allow the kernel workspace to come from the fastest DMA incapable RAM, while also allowing allocation of DMA capable memory for HAL NCNB workspace & kernel cursor/sound chunks. ClearPhysRAM rewritten as part of this.
  * s/MemInfo - Updated to cope with the flags stored in PhysRamTable. Add support for the new OS_Memory 12 flag. Update OS_Memory 7 to not assume PhysRamTable entries are sorted in address order, and rip out the old pre-HAL IOMD implementation.
  * s/NewReset - Remove GetPagesFromFreePool option, assume TRUE (as this has been the case for the past 10+ years). Revise a few comments and strip dead code. Update to cope with PhysRamTable flags.
  * s/VMSAv6 - Remove a couple of unused definitions
  * s/vdu/vdudriver - Update to cope with PhysRamTable flags

Version 5.35, 4.79.2.186. Tagged as 'Kernel-5_35-4_79_2_186'

The three subreasons were being dealt with as follows

8  - time only => convert time; read clock & convert that; mix; to UTC; set
15 - date only => convert date; to UTC; set
24 - both      => convert both; to UTC; set

So subreason 15 ended up setting the clock with the UTC date not taking into account any rollover/under due to the timezone. Now, the behaviour is

15 - date only => convert date; read clock & convert that; mix; to UTC; set

An example program to illustrate this is

 DIM block 128
 REM Example boundary case for -ve timezone
 REM *config.timezone -5
 REM TIME$="Sun,01 Jan 2013.19:01:00"

 REM Example boundary case for +ve timezone

Version 5.35, 4.79.2.185. Tagged as 'Kernel-5_35-4_79_2_185'

hdr/Options: Switch removed
s/Modhand: Switch removed, now considered equivalent to DebugROMInit. DebugROMInit changed so that the callback ordering is as expected, batched up until "callbacks" is hit after Service_PostInit.
PMF/osbyte: Redundant RISC OS 2.01 code deleted

Version 5.35, 4.79.2.184. Tagged as 'Kernel-5_35-4_79_2_184'

Not tagged.

Not tagged.

SystemName, ROMSizeOffset, HAL32, HAL26 only used here, moved here.
Remove uses of "M_" booleans, apparently that's bad form.
Fix SWIDespatch_Size for the non thumb capable case (was ASSERTing).
Swapped UserMemStart for AppSpaceStart.
Removed last use of OldComboSupport (pre Medusa!).
Removed switch 'CDVPoduleIRQs', a correction to the machine definitions mean this can now simply be switched on NumberOfPodules (previously, IOMD couldn't chain podule interrupts).
Take out disabled sub interrupt support - it's in CVS if you want to try to get it working.
Moved ConfiguredLang to 11 for everyone, it only matters if !Boot fails, and no harm in making it common for 5.xx onwards.

Version 5.35, 4.79.2.183. Tagged as 'Kernel-5_35-4_79_2_183'

Add new HAL call, HAL_IRQMax, to allow the kernel to determine the number of IRQ lines/devices at runtime

Detail:
  hdr/HALEntries - Reuse the old HAL_MonitorLeadID call number for HAL_IRQMax
  hdr/KernelWS - Rearrange CursorChunkAddress workspace a bit. Removed unused OldOscliBuffs and a couple of pre-HAL allocations, and made DefIRQ1Vspace the same size for all build configs. Add an IRQMax var to zero page workspace to cache the value returned by HAL_IRQMax.
  s/HAL - Initialise IRQMax shortly after HAL initialisation. Revise ClearPhysRAM comment to reflect which vars are preserved in the current version of the code.
  s/NewIRQs - Strip out a fair bit of pre-HAL code to make the file more readable. Update OS_ClaimDeviceVector/OS_ReleaseDeviceVector to check against IRQMax instead of the MaxInterrupts compile-time limit.
Admin:
  Tested on BB-xM, Iyonix, RiscPC, Pi
  Although the OS will now nominally adapt at runtime to how many IRQ devices there are, it's still using MaxInterrupts as an upper limit as the device claimant table has a fixed memory allocation.


Version 5.35, 4.79.2.182. Tagged as 'Kernel-5_35-4_79_2_182'

OS_CallAfter and OS_CallEvery were treating the delay in R0 as a signed number, limiting its possible range. The PRM didn't require this (a -ve delay doesn't make sense, so implicitly times are unsigned), reworked to allow times up to 0xFFFFFBFF.
Aside:
  OSLib exports these functions as 'int', but it doesn't seem to make a distinction for unsigned versus signed anyway (other unsigned arguments are plain int too)
  The 'callx' library was already prototyped with unsigned times back in 1997

Added comment to hdr/Options about FirstUnpluggableModule - since the keyboard and mouse drivers got moved out of the kernel in 3.50, the original intent (to not allow you to unplug vital modules) has long since been lost, and really the only use of this value is to save 8 bits of CMOS frugal bits.

Version 5.35, 4.79.2.181. Tagged as 'Kernel-5_35-4_79_2_181'

Permits applications to query what value would be used in the event of a CMOS reset for a given configure value. Notably, the configure plugins will use this in favour of 'ResetCMOS'.
hdr/Options: retire the 'Select16BitSound' switch, add comment for ChecksumCMOS switch
hdr/KernelWS: DuffEntry and Nowhere moved here
Kernel.s: Unused OSMD removed, retire single use of SPIRQ in favour of r13_irq
Middle.s: Retire SPIRQ
NewReset.s: Trim out 300+ lines of CMOS reset defaults, call OS_NVMemory 6 instead
PMF/i2cutils.s: CMOS reset default code and table moved here with refactoring
Note, the previous code preserved YearCMOS during the zeroing, only to unconditionally write it later - so have removed it from the zeroing step.
Note, the locations 80-111 are now considered as system CMOS in the allocations hence are now wiped too (previously they got skipped as user CMOS during R-power-on).

Tested on OMAP3 ROM with delete-power-on and R-power-on variants, and a simple BASIC program to read locations 0-255 via OS_NVMemory.

Version 5.35, 4.79.2.179. Tagged as 'Kernel-5_35-4_79_2_179'

Detail:
  s/Middle - Added OS_ReadSysInfo 13 to allow the kernel to validate a key handler before the owner attempts to install it
  Resources/UK/Messages - Text for new "Bad key handler" error
  s/GetAll, s/PMF/Def - Get rid of now obsolete s/PMF/Def file. It only contained definitions for pre-HAL hardware, and for the key handler layout (now in Hdr:Keyboard)
  hdr/KeyWS - Increased size of KeysDown array so it can hold 768 keys instead of 160. Trim a couple of obsolete variables, and increase CurrKey/OldKey from 1 byte to 4 bytes.
  s/PMF/key, s/PMF/osbyte - Main bulk of the changes for the new key handling. All the important interfaces are now able to deal with extended (i.e. > 8 bit) internal key numbers, and the kernel is able to cope with key handlers which use 16 bit internal/low level key numbers instead of 8 bit.
