Sven Schnelle (sv...@stackframe.org) just uploaded a new patch set to gerrit,
which you can find at http://review.coreboot.org/493
-gerrit
commit 5400ae4a51bcfa9dcc580c32bef86aa2a54b59b1
Author: Sven Schnelle <sv...@stackframe.org>
Date: Wed Jun 20 14:56:46 2012 +0200
Add Supermicro X7DB8 motherboard
This adds basic supported for the Supermicro X7DB8. Basic means that
almost all onboard peripherals are working. Known problems are:
- mptable needs to be written dynamically. If you plan to use Add on
cards, modify mptable.c according to your needs. A patch to add generic
mptable autogeneration based on devicetree is coming up.
