PS2, Line 943: return CHIPSET_300_SERIES_CANNON_POINT;
Unfortunately I have not found any documentation related to ICCRIBA. […]
The C621A PCH (used in DeltaLake DVT server) has ICCRIBA as 0x34 and NM as 6. With this code change, flashrom guessed it correctly as CHIPSET_C620_SERIES_LEWISBURG.
If CHIPSET_300_SERIES_CANNON_POINT has 0x34 but NM is never 6, I will use "NM == 6" test to differentiate between CHIPSET_300_SERIES_CANNON_POINT and CHIPSET_C620_SERIES_LEWISBURG..
