* 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)
