Hi Tom,
Please have a look at the fixes below. Basically we fix the rpi_arm64_defconfig which only showed us 1GiB of RAM if we booted using EFI stub. Apart the 32bit config of RPi4 was broken, as it missed the second DRAM bank (and therefore saw only 1 GiB of RAM, even if there was more available).
I run the branch through the gitlab CI, which gave me green light :)
