In lib/efi_loader/efi_boottime.c and in lib/trace.c we are saving and
setting gd.

arch/arm/include/asm/global_data.h defines a function get_gd() which is
used with clang to retrieve the value of gd:

#ifdef __clang__
#define gd      get_gd()

So any statement

gd = foo;

like in __efi_entry_check() is bound to fail with clang.

Does that match your compilation problems with EFI_LOADER=y and clang?

Best regards
