Added: trunk/coreboot-v2/src/superio/serverengines/ trunk/coreboot-v2/src/superio/serverengines/pilot/ trunk/coreboot-v2/src/superio/serverengines/pilot/pilot.h trunk/coreboot-v2/src/superio/serverengines/pilot/pilot_early_init.c trunk/coreboot-v2/src/superio/serverengines/pilot/pilot_early_serial.c Log: This patch add rudimentary support for the superio functionality of the Serverengines Pilot BMC chip. Necessary to get serial out on the HP DL145 G3.
