Changes since U-Boot 0.4.0:
======================================================================
* Rewrite command lookup and help command (fix problems with bubble
sort when sorting command name list). Minor cleanup here and there.
* Merge from "stable branch", tag LABEL_2003_06_28_1800-stable:
- Allow to call sysmon function interactively
- PIC on LWMON board needs delay after power-on
