[coreboot] [review 1/2] Subject: Prepare for Clevo D900T
Pat Erley
pat-lkml at erley.org
Thu Apr 29 20:16:34 CEST 2010
This adds a preliminary clevo/d900t target for me to use as I
add new support for:
* ICH6
* i915P
* Socket 775
* New P4 Procs
* NSC PC87393F Super I/O
So that successful build can be shown with each additional chip
addition.
Based on intel/d945gclf
