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

[Sandy Zhang]

Hi David,

It seems that the below 2 regions are "write denied":

00A26000       00A35FFF     00010000        DER #1 Region
00A36000       00FEFFFF     005BA000        10 Gbe A Region

By the way, can you tell me what is the other parament "EW", "S" and "E"
meana? thank you!
