- Fix some copy bugs and thinkos in the i440bx SMbus
read code. SBbus reads to RAM now work. Yah! - Rename the register constants to something I can look at more easily. - Make the logic flow match the flow from V1 assembly - #if 0 out other SMbus functions that are still broken. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2353 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
