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 ;) Signed-off-by: Rudolf Marek <r.marek@assembler.cz> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5560 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
