      Safe GPIO pins table updates · b0ddf21a
      Robert Sprowson authored
      Add Pi3 B+ and Zero W.
      Split out CM3 from CM1, since the CM3 reuses some high GPIO lines as bit bashed SMPSU IIC bus, so we can't offer those for GPIO like on CM1.
      Version 0.75. Tagged as 'BCM2835-0_75'

      Add new scheme ids for A+ and B+ to id table · 2e99b15b
      Robert Sprowson authored
      Apparently there are some A+ 1.1 and B+ 1.2's in the wild not built with their former id's (0x12 and 0x13) but using the newer 24 bit id scheme. Add aliases for these.

      Transition Pi HAL to GPIO API 1.00 · d3f4d7ef
      ROOL authored
        Move the register accesses for GPIO to the HAL, since they are hardware specific.
        Add recognition of board types for Pi 3, Compute module 3, rev 3 Pi 0's, and the newer Pi 2's with BCM2837 on them.
        Based in part on a submission from Tank.
        Tested on a Pi 2. Requires corresponding GPIO module (tag GPIO-1_00-1_11_2_1 or later).

      Add JTAG debugging support · e626e215
      Jeffrey Lee authored
        hdr/BCM2835 - Add switch to allow GPIOs 22-27 to be reconfigured for ARM JTAG access
        s/Top - Configure GPIOs for JTAG if switch enabled
        s/GPIO - Disable GPIO HAL device if JTAG enabled (try and avoid any software messing with the pins)
        Tested on Raspberry Pi 1 B, B+

      Fix build error. Add HAL_PlatformName implementation. · 419bb1d2
      Jeffrey Lee authored
        s/Stubs, s/Top - Remove references to deleted HAL ATA calls
        s/GPIO, s/Top - Add implementation of HAL_PlatformName. Located in s/GPIO to allow easy re-use of the board revision table.
        Tested on Pi 2 Model B

      Add entry to boardtypes for GPIO for Compute module · de83026a
      Robert Sprowson authored
      There doesn't seem to be a pattern emerging for the allocation of board types, so it's likely that this table will need revisiting again in future as moving the catch all "-1" entry along was identifying a Compute module as a B+.
      Submission from TankStage.

      Support the Raspberry Pi model B+ · 4830dcfe
      Ben Avison authored
        The activity GPIO pin has been reassigned and its sense is inverted,
        compared to earlier boards. More importantly, the SD card detect pin has
        been removed entirely, so we need to signal to the SD stack to use its
        new timeout-based state machine (rather than polling for card presence).
        Already in use in RC12a.

      Read board model, revision, and available DMA channels from messaging channel.... · 59e36802
      Jeffrey Lee authored
      Read board model, revision, and available DMA channels from messaging channel. Report board revision via GPIO HAL device. Recover lost ROM relocation code.
        hdr/StaticWS, s/Messaging, s/Top - Now reads board model, revision and available DMA channels from messaging channel
        hdr/StaticWS, s/GPIO - Updated GPIO HAL device to report board revision instead of a generic response of 'unknown'
        s/Top - Recovered ROM relocation code that got lost during a merge. End of ROM image no longer being corrupted, and RISC OS now sees correct amount of RAM.
        s/DMA - Ditch old code to read available DMA channels and use value read by HAL_QueryPlatform instead.
        Tested on Raspberry Pi (B rev 1) with various start.elf sizes & versions
        DMA channel reporting only available with latest firmware (i.e. 8th Sep)
        Board revision number read by messaging channel seems to match that returned by /proc/cpuinfo on Linux

      Add GPIO & VCHIQ HAL devices. Fix FlushDataCache macro to perform a clean & invalidate instead of just an invalidate.
        s/GPIO - Basic implementation of the GPIO HAL device to allow the GPIO module to detect the board type
        s/VCHIQ, hdr/StaticWS - New VCHIQ HAL device which exposes the functionality required by the work-in-progress VCHIQ driver.
        Makefile, s/Top - Hook up the new files/devices
        hdr/BCM2835 - Make the FlushDataCache macro perform a clean & invalidate, to match the behaviour of FlushDataCacheRange
        Tested on Raspberry Pi with high processor vectors
      Version 0.17. Tagged as 'BCM2835-0_17'
