Looks like the UEFI Shell requires the v1 GUID of the collation protocol. Please add and advertise that too.

Hello Alex,

that protocol does not exist in the UEFI 2.7 spec and it is not required to run EDK2 ./ShellBinPkg/UefiShell/AArch64/Shell.efi on qemu_arm64_defconfig.

I just removed your patch XXX efi_loader collation: Expose v1 GUID as well from https://github.com/agraf/u-boot/commits/ebbr-demo and I am still able to run Shell.efi.

Best regards

Heinrich
