commit 144801207d5b1ad494d7b89b8c7156f8ae7ebd22 Author: Oskar Enoksson enok@lysator.liu.se Date: Tue Oct 4 22:34:11 2011 +0200
Re-worked devicetree.cb for DL145 G1
After a lot of experimentation this commit improves some hardware features that were not recognized or incorrectly configured before. The only thing not tested is SCSI-option board (I dont have one). Misleading errors in comments have been corrected. (Note BTW that the DL145 G1 mainboard is identical to AMD Serenade which was supported in early versions of coreboot but was dropped for some reason.)
