Subject[PATCH 10/25] efi/libstub: drop explicit 32/64-bit protocol definitions
Date
Now that we have incorporated the mixed mode protocol definitions
into the native ones using unions, we no longer need the separate
32/64 bit struct definitions, with the exception of the EFI system
table definition and the boot services, runtime services and
configuration table definitions. So drop the unused ones.
