Lukas Wunner 3552fdf29f efi: Allow bitness-agnostic protocol calls ... We already have a macro to invoke boot services which on x86 adapts automatically to the bitness of the EFI firmware: efi_call_early(). The macro allows sharing of functions across arches and bitness variants as long as those functions only call boot services. However in practice functions in the EFI stub contain a mix of boot services calls and protocol calls. Add an efi_call_proto() macro for bitness-agnostic protocol calls to allow sharing more code across arches as well as deduplicating 32 bit and 64 bit code paths. On x86, implement it using a new efi_table_attr() macro for bitness- agnostic table lookups. Refactor efi_call_early() to make use of the same macro. (The resulting object code remains identical.)
