Add initial framework for the Tyan S1846.
It's not fully working, among other things because the Intel 440BX northbridge isn't working, yet. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Ronald G. Minnich <rminnich@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2580 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
