* 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)
