Change read_option() to a macro that wraps some API uglyness
Simplify read_option(CMOS_VSTART_foo, CMOS_VLEN_foo, somedefault) to read_option(foo, somedefault) Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Acked-by: Stefan Reinauer <stefan.reinauer@coreboot.org> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6565 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
