This adds a mptable for the VIA pc2500e. I've tested with the devices
in the VT8237R, and a card interrupting at Pin-A on either PCI slot. Signed-off-by: Jonathan A. Kollasch <jakllsch@kollasch.net> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3826 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
