I wonder if this means we should also do:

Sets the size of the bloblist in bytes after relocation. Since U-Boot
Because in this case we do need to set the size of the bloblist we use
internally to non-zero?
That makes sense. The relocation in board_f will fail, as
reserve_bloblist relies on this value being non-zero. However, if
CONFIG_BLOBLIST_PASSAGE implies GD_FLG_SKIP_RELOC, then the relocation
may not be necessary?
