So I've added Jeremy to my reply as he's the maintainer of this
firmware but as it's EDK2 and ACPI, as opposed to device tree, I'm not
sure it's intended to work.
As the driver would need ACPI support and the firmware would need the
appropriate ACPI tables to describe the hardware. I'm not sure what
the plans there are for support for the GPU on that firmware is, the
timeline or if there is any plans there.
Plans yes, no dates.
I would suggest that if it works with a mainline overlay it should be
possible to put that in the overlay's directory and add it to the
config.txt and change it from ACPI->DT in the firmware. But.. at the
moment you also should probably make sure your also changing the SD
config for DT too (it will be in the next release).
So at the moment your sorta going to have to hack it on your own, the
few of us patching the uefi firmware have our hands full with various
boot failures that have crept up over the last month too :(
(PXE, USB and SD failures have been burning most of my spare time, did
you know people were iscsi booting the rpi too? LOL)
