Re: [flashrom] When flashrom support Intel Purley platform Lewisburg PCH?

[David Hendricks]

Hi Sandy,
It might not have done what you expect. The error is because offsets
0xa26000-0xffffff are not defined in the flash descriptor, so the PCH gives
us an error when flashrom attempts to update it. ":WD" next to the offsets
in the log means "write denied".

If you wish to update that region of the ROM then you must change your
flash descriptor to include it and set the permissions to enable read and
write.
