Author: ruik Date: Sun May 16 17:31:53 2010 New Revision: 5560 URL: https://tracker.coreboot.org/trac/coreboot/changeset/5560
Log: Following patch reprograms SIL3114 into PCI IDE native mode compatible class code allowing legacy software to recognize it as IDE and boot from it. I think this should be the default for two Tyan boards (k8s aka s2882 and s2881).
Rename the directory to sil prefix to match the Linux kernel naming. (And I think it was a SiliconSystems wish to be named sil ;)
