   trunk/coreboot-v2/src/southbridge/amd/sb600/sb600.c

Log:
I/O ports are 16bit, so change 'unsigned long port_base' to 'u16 port_base'.
Also, use more readable #defines instead of hardcoded config ports for
PM/PM2 related functions, and simplify them a bit.

Build-tested with the AMD dbm690t target.
