Add support for the Intel 82371MX (MPIIX) southbridge (trivial).
Untested, but should work just as well as the other *PIIX* southbridges according to the datasheets. 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@3696 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
