Changes since U-Boot 1.0.0:
======================================================================
* Patch by Reinhard Meyer, 28 Dec 2003:
Add initial support for TOP5200 board
* Make CPU clock on ICA-IP board controllable by a "cpuclk"
environment variable which can set to "100", "133", or "150". The
CPU clock will be configured accordingly upon next reboot. Other
