In efi_add_known_memory() we currently call board_get_usable_ram_top() with an incorrect value 0 of parameter total_size. This leads to an incorrect value for ram_top depending on the code in board_get_usable_ram_top().
Use the value of gd->ram_top instead which is set before relocation by calling board_get_usable_ram_top().
