Currently, GenFv warns about input files without a relocation section, but still includes the FFS file in the image, but with its ImageBase field left at zero. This confuses the loader routines in PEI core, resulting in spurious write attempts to be made at the NOR flash. When using the GCC LTO compiler for AArch64, the optimizations are so effective that in some cases, all absolute symbol references are optimized away completely, resulting in a PE/COFF image that has no .reloc section at all (i.e., the PE/COFF image is position independent, but purely by accident) This means that, while unusual, it is not an error for a XIP image to have no .reloc section. So teach GenFv about this, i.e., let it skip the relocation routines, but still update the ImageBase address in the header, and recalculate the checksums.
