Yes and no? Check this:

http://www.coreboot.org/Memory_map

Also MMCONFIG region should be somewhere. For VIAs, the static resources are in 
.h files in V2
http://tracker.coreboot.org/trac/coreboot/browser/trunk/coreboot-v2/src/southbridge/via/k8t890/k8t890.h
http://tracker.coreboot.org/trac/coreboot/browser/trunk/coreboot-v2/src/southbridge/via/vt8237r/vt8237r.h

Problem is that some resources (APICs can be only on arbitrary range, typically 
0xfec0 0000 - 0xfecf ffff

So DEVICE_MEM_HIGH should be lower then those .h files?? And IO_LOW would be 
nice too...
