Today I try the way you suggested. Set USE_SET_VIRTUAL_ADDRESS_MAP on
ARM and make a fake efi_rs_enter() and efi_rs_leave(). But when calling
efi_init_memory, it fails with below log:
You can't just #define that constant and assume things will work: This
code is there so far only for documentation purposes. You need to go
look what parts of it may have bitrotted.
It fails at below line:
efi_rs->SetVirtualAddressMap(efi_memmap_size, efi_mdesc_size,
mdesc_ver, efi_memmap);
Quite obviously because efi_exit_boot() now sets efi_bs to NULL.
I see in efi_start() there is below code setting efi_bs to NULL. But
here it calls efi_rs not efi_bs. I don't understand the relation of them.
status = SystemTable->BootServices->ExitBootServices(ImageHandle,
map_key);
efi_bs = NULL;
