The add_u_boot_and_runtime() function paints with a broad brush, considering all of the memory from the top of U-Boot stack to gd->ram_top as EFI_RUNTIME_SERVICES_CODE This is fine, but we need to make sure we don't add a separate entry for any ACPI tables in this region (which happens when bloblist is used for tables). Otherwise the memory map looks strange and we get a test failure on qemu-x86 (only) for the 'virtual address map' test.
