Following patch fixes the boot_switch_sata_ide logic. It can swap
primary / secondary IDE channel with SATA (in IDE mode). The bug was that setup was done in wrong device. Signed-off-by: Rudolf Marek <r.marek@assembler.cz> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5932 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
