Changes for U-Boot 1.0.0:
======================================================================
+* Make sure HUSH is initialized for running auto-update scripts
+
+* Make 5200 reset command _really_ reset the board, without running
+ any other code after it
+
+* Fix errors with flash erase when range spans across banks
+ that are mapped in reverse order
+
+* Fix flash mapping and display on P3G4 board
+
+* Patch by Kyle Harris, 15 Jul 2003:
+ - add support for Intel IXP425 CPU
+ - add support for IXDP425 eval board
+
* Added config option CONFIG_SILENT_CONSOLE. See doc/README.silent
