      Add basic HAL device for the official DSI display/touchscreen. Delete superfluous code. · 76db1228
      Jeffrey Lee authored
      Detail:
        Makefile, s/Touch - Basic HAL device for the official touchscreen, which just exposes the address of the buffer which the GPU periodically fills with a register dump of the touchscreen controller.
        hdr/BCM2835 - Remove old comment. Add new tag for getting the touchscreen buffer address.
        hdr/StaticWS - Remove old workspace entries. Add new entries for touchscreen.
        s/Messaging - Remove the messagebox tags which set a screen mode on startup (BCMVideo will handle that for us), and just blank the screen instead (to stop the GPU displaying a coloured square). Add tag to get the touchscreen buffer address.
        s/Top - Register touchscreen HAL device during HAL_InitDevices. Remove more old code.

      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
      Detail:
        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).
      Admin:
        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.
      
      Detail:
        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.
      Admin:
        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.
      
      Detail:
        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
