This patch adds support for mainboard iBASE:MB899
based on Kontron 986LCD-M changed superIO chip to w83627ehg, dropping MIDI dropped second superIO at 4e changed superIO-addr from 2e to 4e adjusted irq_tables.c and devicetree.cb dropped setup of 3xGBit-Ethernet adjusted IRQ-map (using values from mainboard/intel/d945gclf) disabled parts about HD-audio (missing on that board) Signed-off-by: Bernhard M. Wiedemann <corebootbmw@lsmod.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5599 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
