Simplify a few code chunks, fix whitespace and indentation.
Also, remove some less useful comments, some dead code / unused functions. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6108 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
