New Revision: 5673
URL: https://tracker.coreboot.org/trac/coreboot/changeset/5673
Log:
Add support for the Intel Atom D400/500- and N400-series integrated
northbridge. Also add support for the very similar Q963/965 northbridge.
Tested:
D510: confirmed working, with MCHBAR enable code
Q965: writes to bit 0 to enable MCHBAR access are ignored, all other functions work
Untested:
D410/D525/N400: should be the same northbridge
