This is a good idea, but some of grub file names don't match the arch name
in the triple,
- i386: grub_x86.efi
- x86_64: grub_x64.efi
- arm: grubarm.efi
- aarch64: grubaa64.efi
- riscv64: grubriscv64.efi
- loongarch64: grubloongarch64.efi
so we need a mapping between them, maybe a bash array. Or, these names
seem to be refered only in u-boot-test-hooks as
env__efi_loader_grub_file, so I think alternatively we could update the
repository to use file names consistent with the tripple.
I'd prefer the latter since it looks cleaner, though the change might be
a little complex to fit in this series (involving updating workflow and
u-boot-test-hooks in a correct order so no CI run gets broken).
