Added: trunk/LinuxBIOSv2/src/superio/smsc/fdc37m60x/ trunk/LinuxBIOSv2/src/superio/smsc/fdc37m60x/Config.lb trunk/LinuxBIOSv2/src/superio/smsc/fdc37m60x/chip.h trunk/LinuxBIOSv2/src/superio/smsc/fdc37m60x/fdc37m60x.h trunk/LinuxBIOSv2/src/superio/smsc/fdc37m60x/fdc37m60x_early_serial.c trunk/LinuxBIOSv2/src/superio/smsc/fdc37m60x/superio.c Log: Add support for the SMSC FDC37M60x Super I/O (tested on FDC37M602).
Serial output on serial port 1 is tested and works, the rest probably not yet.
Closes #59.
