Now with 8GiB (yay!) support!
What’s inside this release?
- Add UEFI Shell to Boot Manager menu [tianocore/edk2-platforms@1c31eea]
- Add support for 8 GB Raspberry Pi 4 models [tianocore/edk2-platforms@dae68d5, tianocore/edk2-platforms@678f6bf]
The 8GiB variant changes the board layout a bit, dropping the SPI EEPROM containing the xHCI (USB3 controller) microcode, which required the relevant code to be added to UEFI to load it during boot. The good news is that the same approach is harmless on the other (1GiB, 2GiB and 4GiB Pies).
Like the 4GiB variant, UEFI will default to booting with only 3GiB to deal with OSes that can’t process the ACPI-reported DMA limits.
Of course, without the 3GiB limit, you get the full 8GiB (minus the gpu_mem amount anyway).
Booting to UEFI Shell should be a bit less awkward now, now that it is permanent to the Boot Manager menu.
As always, read the release notes and usual caveats.
