some progress on kconfig:

some progress on kconfig:
- northbridges are done
- southbridges are done
- Intel CPUs are done, with a design that the board only has to specify
  the socket it has, and the CPUs are pulled in automatically. There is
  some more cleanup possible in that area, but I'll do that later
- a couple more mainboards compile:
  - intel/eagleheights
  - intel/jarrell
  - intel/mtarvon
  - intel/truxton
  - intel/xe7501devkit
  - sunw/ultra40
  - supermicro/h8dme
  - tyan/s2850
  - tyan/s2875
  - via/epia
  - via/epia-cn
  - via/epia-m
  - via/epia-m700
  - via/epia-n
  - via/pc2500e
(PPC not considered, probably overlooked something)

All of them only _build_, but some options are probably completely
wrong. To be fixed later
