this patch needs the patch from:
http://www.linuxbios.org/pipermail/linuxbios/2007-November/027287.html
to be inserted first.

it fixes non working erasing in that patch (original flashrom code also is nonworking) the erasing part of writing did work because that used erase_block_jedec and not erase_chip_jedec
datasheets says: "Chip erase is available in A/A Mux Mode only."
