GitLab

Detail:
  Use symbol instead of magic 6. Comment correction.
Admin:
  Binary unchanged. Retagged as 'OMAP3-1_18'.

Update to API 1.0, and corresponding set of register wide accessor functions.
The tables of permitted pins come from staring at the schematics for any connectors, minus those that are "owned" by the OS.
In the absence of any Touchbook schematics, no GPIO device will be registered for this (given the physical size of the Touchbook it's unlikely there are any usefully accessible headers anyway).

Tested on a BB-xM, toggling the two user LEDs and scanning the 'USER' push button.

Version 1.18. Tagged as 'OMAP3-1_18'

Detail:
  SDIO.s comment correction
  hdr/StaticWS removed unused USBAllocArea
Admin:
  From similar change in OMAP4-0_57.

Version 1.17. Tagged as 'OMAP3-1_17'

Adopt the board type and revision enum privately in board.hdr (mass search & replace exercise).
Don't re-export it via a stub GPIO device; it's private.

Version 1.16. Tagged as 'OMAP3-1_16'

Detail:
  Replace keyboard scan code with list of modules that the kernel needs to do the same.
  Reorder the HALEntries to match Kernel-5_89.
  Delete unused workspace.
  Don't link against HAL USB library.
Admin:
  Submission for USB bounty.

Version 1.15. Tagged as 'OMAP3-1_15'

Admin:
  As a side effect of changes in USBDriver-1_20, rename the library object.

Version 1.14. Tagged as 'OMAP3-1_14'

Detail:
  hdr/omap3530, s/SDIO - Change writes to L4_PBiasLite to go via a function so that we can avoid altering the PBIAS1 settings when we're using a 4 bit SD interface. Also make sure the GPIO_IO_PWRDNZ bit that's present on DM37x chips reflects the value of PBIASLITEPWRDNZ1.
  s/Boot - When adjusting VSIM during enabling of the battery charger, make sure to set the PBIAS1 controls to high impedence to protect the GPIOs.
Admin:
  Tested on (OMAP3) Pandora, BeagleBoard-xM
  May fix issue reported with 1GHz (i.e. DM37x) Pandora where 2nd SD slot activity LED (which uses one of the GPIOs that are routed through PBIAS1) doesn't work


Version 1.13. Tagged as 'OMAP3-1_13'

Detail:
  s/RTC - Copy over the DS1307/DS1338 driver from the OMAP4 HAL, in order to allow TouchBook owners to make use of such a chip if they attach it to I2C3 (since the TPS isn't battery-backed on that machine)
Admin:
  Tested on TouchBook


Version 1.12. Tagged as 'OMAP3-1_12'

Detail:
  s/BMU - Reading the BQ27200 flags variable was always reporting an "error" result, due to a1 not being set correctly prior to the branch. Also the 'charging' flag was being missed off due to erroneous use of LDRB.
Admin:
  Tested on TouchBook
  Fixes 2nd battery (keyboard unit) always showing as 'unknown' state in BatMgr's display (dark grey with charge stripes) when the keyboard is connected
  Issue spotted by Raik Fischer


Version 1.11. Tagged as 'OMAP3-1_11'

Detail:
  s/SDIO - Add a GET of Hdr:CPU.Arch, as it's now required for DivRem usage
Admin:
  Untested


Version 1.10. Tagged as 'OMAP3-1_10'

Detail:
  s/Boot, s/Interrupts, s/Timers - Move timer IRQ clear code out of HAL_IRQClear and into HAL_TimerIRQClear. Streamlines HAL_IRQClear and allows timers to be used by FIQ handlers.
Admin:
  Tested on BB-xM


Version 1.09. Tagged as 'OMAP3-1_09'

Detail:
  s/Boot, Makefile, s/Stubs - Remove references to deleted HAL ATA calls. Delete s/Subs it's now redundant.
  hdr/board, s/board, s/Top - Refactor how board names are stored so that we can differentiate between OMAP3 and DM37x versions of boards (at least the BeagleBoard and the Pandora come in OMAP3 and DM37x variants)
  s/Boot - Add HAL_PlatformName implementation, using the new board name system
Admin:
  Tested on BB-xM


Version 1.08. Tagged as 'OMAP3-1_08'

Detail:
  Extra entry to get the die temperature, as reported by Portable_ReadSensor(0,0,0).
Admin:
  Submission from Willi Theiss.
  Tested on IGEPv2 and BBxM.

Version 1.07. Tagged as 'OMAP3-1_07'

omap3530.hdr/Debug,s:
  Define a dummy symbol so when debug is enabled there aren't conflicting IMPORT and EXPORTs.
Boot.s:
  Update comment to match HAL function names.

Version 1.06. Tagged as 'OMAP3-1_06'

Detail:
  s/SDMA - Add extra memory barriers to DMA code, ready for when the default NCB memory cache policy is changed from Device to Normal, non-cacheable (increased risk of out-of-order accesses)
Admin:
  Tested on BB-xM


Version 1.05. Tagged as 'OMAP3-1_05'

Anyone using the serial port for other peripheral uses might get confused if some HAL debug comes out on it.
Move the IMPORTs into a header so we don't end up with lots of unresolved symbols with Debug {FALSE}.
Rename a couple of symbols in PAudio missed in OMAP3-1_03.
Built, but not tested.


Version 1.04. Tagged as 'OMAP3-1_04'

Updated for Sound0HAL-1_80.

Version 1.03. Tagged as 'OMAP3-1_03'

Detail:
  s/Boot, s/SDIO - Add support for the TouchBook's SD slot. Although the Linux sources suggest it should be the same configuration as a BeagleBoard, it doesn't look like the card detect or write protect lines are functional on my unit, so we avoid using them.
Admin:
  Tested on rev C1 TouchBook


Version 1.02. Tagged as 'OMAP3-1_02'

Since this HAL targets the A8, it's a nice simple L2EN bit set.
Also, correct the range of SDRAM hinted to the kernel - the DRAM controller only has enough lines to control 1GB not 2 as previously claimed.

Version 1.01. Tagged as 'OMAP3-1_01'

Version 1.00. Tagged as 'OMAP3-1_00'

HAL_HardwareInfo - as word 0 specified that no IOMD or VIDC was present, don't waste time reporting anything in word 2.
Not tagged.

Version 0.99. Tagged as 'OMAP3-0_99'

As the flag bit in HAL_USBControllerInfo isn't set, no need to provide them.
Use symbols from Hdr:HALEntries when building the USB info.
No need for AASMFLAGS in the makefile.
Built, but not tested.

Version 0.98. Tagged as 'OMAP3-0_98'

Disallow EDID writes. Add support for EDID reads which require the segment pointer to be set. Improve Pandora screen blanking.

Detail:
  s/I2C - Revise HAL_VideoIICOp implementation to disallow EDID writes (&A0 IIC address). Attempt to write the EDID segment pointer when accessing EDID addresses >= 256.
  s/Video - Make Pandora screen blanking put the LCD into/out of standby mode. If it's left active while the video sync signals are cut then there'll often be garbage displayed on the screen.
Admin:
  Tested on BB-xM, Pandora


Version 0.97. Tagged as 'OMAP3-0_97'

Version 0.96. Tagged as 'OMAP3-0_96'

Reflects similar change in OMAP4-0_28.
Built, but not tested.

Version 0.95. Tagged as 'OMAP3-0_95'

Detail:
  s/board - Re-enable Pandora TV-out support now that we have the ability to turn TV-out power on/off
  hdr/board, s/Video - Add the new TV-out power control function to the video board config struct. All OMAP boards should be able to use the same implementation, which enables/disables the VDAC power supply in the TPS
Admin:
  Tested on BB-xM and Pandora
  TV detection (and TV-out in general) now works properly on the Pandora


Version 0.94. Tagged as 'OMAP3-0_94'

Detail:
  s/PAudio - Change the Pandora audio device over to API version 2 so that we can specify the stereo reverse flag
  s/Audio - Adjust workspace of the audio device used by the other machines so that it's still the same size as the Pandora one. Note that the stereo reverse flag isn't needed - although I can't remember how I'm doing it, it seems there's some TWL feature which I'm making use of on other machines to deal with the stereo reversal there, as the hardware doesn't use VIDC channel order by default
  hdr/Audio - Adjust size of the shared audio device workspace
Admin:
  Tested on Pandora & BB-xM


Version 0.93. Tagged as 'OMAP3-0_93'

Detail:
  hdr/Video, s/Top - Remove local VIDC list type 3 definition, use Hdr:VIDCList instead
  s/Boot, s/Video - Removed obsolete HAL video API implementation. A stub implementation is no longer required for systems that have a GraphicsV driver in a module, and can even cause problems if the OS decides to use the HAL implementation instead of the module one.
Admin:
  Tested in OMAP3 ROM on BB-xM
  Requires Kernel-5_35-4_79_2_203


Version 0.92. Tagged as 'OMAP3-0_92'

Spotted by Willi Theiss.

Version 0.91. Tagged as 'OMAP3-0_91'

- Comments and symbolic names for RTC register bits copied over from OMAP4 sources.
- Delete dead function ReadTimeForNVRAM.
- Use RTCFormatFlags_BCD_NeedsYearHelp flag for year 2070 compatibility.
- Moved CallOS macro into a header.
Tested on a Beagleboard xM, clock still worked over a power cycle.

Version 0.90. Tagged as 'OMAP3-0_90'

Now assumes an IICStatus return, per Kernel-5_35-4_79_2_196.
I2C sources lined up to column 17.
Built, but not tested.

Version 0.89. Tagged as 'OMAP3-0_89'

Revision 0.87 moved the NVMemory probe too late for the kernel, which fell back to using its default table.
Fixes problem of apparently lost configuration
  http://www.riscosopen.org/forum/forums/4/topics/2063
Video_Init capitalised like the other initialisation functions.

Version 0.88. Tagged as 'OMAP3-0_88'

The HAL device created is merely a dummy one, but presents any EEPROM detected for completeness of stuff the HAL knows about.

Version 0.87. Tagged as 'OMAP3-0_87'

Detail:
  s/SDIO - Disabled SD write protect sensing on Pandora, as hardware faults can result in some units always reporting that cards are protected
Admin:
  Tested briefly on Pandora, write-protected cards can be written to
  Should fix issue reported on forums with unprotected cards being reported as read-only:

Version 0.86. Tagged as 'OMAP3-0_86'

Detail:
  s/Boot, s/Interrupts - Added HAL_IRQMax implementation, to ensure correct functionality with latest Kernel
Admin:
  Tested on BB-xM
  Requires Kernel-5_35-4_79_2_182


Version 0.85. Tagged as 'OMAP3-0_85'

Detail:
  s/Video - Added code to program the gamma table in the Pandora's LCD, as the power-on settings aren't very good
  s/Boot - Initialise the LCD at the right time
  hdr/SPI - SPI register definitions, for programming the gamma table and (eventually) a full SPI driver
Admin:
  Tested on Pandora


Version 0.84. Tagged as 'OMAP3-0_84'

Detail:
  s/BMU, Makefile - BMU HAL device implementations for the Pandora & TouchBook
  hdr/StaticWS - Reserve workspace for the BMU devices
  s/Boot - Add the BMU devices to HAL device initialisation. Move Enable_main_battery_charging into s/BMU.
Admin:
  Tested in ROM on BB-xM, Pandora, TouchBook


Version 0.83. Tagged as 'OMAP3-0_83'

Detail:
  hdr/CPUClk, hdr/SR37x, s/Boot, s/CPUClk, s/SR37x - Modifed CPU clock drivers to allow the core speed & voltage to be reset to the power on defaults prior to reset/poweroff. This fixes an issue seen on Pandora where Linux will often fail to boot after RISC OS has been run, presumably due to VDD1 being too low for the initial clock speed Linux switches to.
  s/Boot - Place EHCI PHY in reset prior to reset/power off. May help with a reported issue of USB host being unreliable after RISC OS has been run (although reset/poweroff should reset the GPIO anyway)
Admin:
  Tested on Pandora & BB-xM
