[U-Boot] [PATCH v2 1/7] efi_loader: Change return type of efi_add_memory_map()

[Bryan O'Donoghue]

We currently have some inconsistent use of efi_add_memory_map()
throughout the code. In particular the return value of efi_add_memory_map()
is not interpreted the same way by various users in the codebase.

This patch changes efi_add_memory_map() to return efi_status_t. A
subsequent set of patches will change the internal values themselves and
finally the users of efi_add_memory_map().
