Hi,

the problem is that the regions in the flash descriptor do not cover
the whole address space of the chip. The is a hole between FREG0 and
FREG1 from 0x10000 to 0x3fffff. The chipset does not allow any accesses
to these uncovered addresses but flashrom usually reads and writes the
complete chip. The easiest way to fix this is to change the flash
descriptor and extend FREG1 so that it starts immediately after FREG0
at 0x10000 (with an external programmer).
