======================================================================
Changes for U-Boot 1.1.3:
======================================================================
+* Patch by Jon Loeliger, 2005-07-25
+ Move the TSEC driver out of cpu/mpc85xx as it will be shared
+ by the upcoming mpc83xx family as well.
+
* Patch by Jon Loeliger, 2005-05-05
Implemented support for MPC8548CDS board.
Added DDR II support based on SPD values for MPC85xx boards.
