The original IFD defines the BIOS region as the whole flash chip. While this is
not an issue if flashing a complete image, it confuses flashrom and trashes the
-flash chip's contents when using the --ifd option. However, this can be easily
-fixed by reading the IFD with flashrom, editing the correct values into it with
-ifdtool and then reflashing it.

+to create a `layout.txt` file with a non-overlapping BIOS region:

-ifdtool -n layout.txt ifd.rom

-If only a reboot is done, the old IFD layout is still seen by flashrom, even if
-the IFD on the flash chip is correctly defining the new region layout.
