From: Simon Glass <simon.glass@canonical.com> When GD_FLG_SKIP_RELOC is set (e.g. for EFI applications), U-Boot does not relocate itself, so the reserved FDT destination address is not valid. Attempting to memcpy the FDT to this address causes a page fault on RISC-V EFI apps. Add a GD_FLG_SKIP_RELOC check before the FDT copy in reloc_and_fix_fdt() so the FDT blob pointer is left unchanged when relocation is skipped.
