* Code cleanup

* Patch by Sascha Hauer, 28 Jun:
  - add generic support for Motorola i.MX architecture
  - add support for mx1ads, mx1fs2 and scb9328 boards

* Patches by Marc Leeman, 23 Jul 2004:
  - Add define for the PCI/Memory Buffer Configuration Register
  - corrected comments in cpu/mpc824x/cpu_init.c

* Add support for multiple serial interfaces
  (for example to allow modem dial-in / dial-out)
