[PATCH 1/6] board_f: Add support for CONFIG_OF_BOARD_FIXUP for XIP images

From: Pali Rohár When U-Boot is running from flash memory (execute in place) then gd->fdt_blob before relocation points to read-only flash memory. So U-Boot calls board_fix_fdt() with read-only gd->fdt_blob pointer which cause immediate CPU crash when callback is trying to modify gd->fdt_blob.
