Changes for U-Boot 1.0.2:
======================================================================
+* Patch by Pierre Aubert, 26 Feb 2004
+ add IDE support for MPC5200
+
+* Patch by Masami Komiya, 26 Feb 2004:
+ add autoload via NFS
+
+* Patch by Stephen Williams
+ Use of CONFIG_SERIAL_SOFTWARE_FIFO in board.c consistent with uses
+ elsewhere in the source.
+
* Patch by Steven Scholz, 25 Feb 2004:
