much closer. Still need i2cmux bits. Do that tomorrow. It's midnight here. 

We do need to standardize on style. To save some makefile work I am 
doing things like this:
subdirs-$(CONFIG_NORTHBRIDGE_AMD_AMDK8) += amdk8

I think that's a good idea but the idea is not universal. 

Also, I don't think src/cpu/*/Makefile.inc files should ever include 
anything other than socket directories. Sockets drive everything. 

Please see: 
src/cpu/amd/Makefile.inc 
src/cpu/amd/socket_F/Makefile.inc 

For how I think it ought to work. src/cpu/intel/Makefile.inc violates this
rule. 

We need to formalize some of the Makefile.inc style.
