[edk2-devel] [PATCH v3 0/4] RPi: SD/WiFi ACPI updates

[jlinton]

From: Jeremy Linton <jeremy.linton at arm.com>

The existing RPi3 ACPI entries for the Arasan
and SDHCI controllers need updating to work
with the RPi4. This is done by adding a caps
override for the legacy Arasan controller and
then adding an entirely new entry for the newer
eMMC2 controller.

Then we flip the default routing to make the eMMC2
the default for the SD card, so that the WiFi can
start working on the Arasan.

Additional we add a menu item to enable the SDMA/ADMA2
modes on the controller.

v2->v3: Various small review tweaks, whitespace, wording
            spelling, etc.

v1->v2: Add option for user to enable/disable eMMC DMA
        Only enable the emmc2 table on rpi4 & 
            !Arasan routing
        Move emmc2 into its own SSDT and drop 
            second _DMA entry

Jeremy Linton (4):
  Platform/RaspberryPi: Add Negative table check
  Platform/RaspberryPi/Acpitables: Add eMMC2 device and tweak Arasan
  Platform/RaspberryPi: User control of eMMC2 DMA
  Platform/RaspberryPi: Invert default Arasan, eMMC2 routing
