This is not an optimal way to solve this.
I just checked in patches for U-Boot to allow for a "low-boot"
configuration, i. e. you can configure and built U-Boot using the
commands "make MPC5200LITE_LOWBOOT_config;make all" and then program
it at the low end of the flash (0xFF000000). After switching the boot
high/low jumper ("B H/L") the board will boot directly into U-Boot
and all you need to switch back to dBUG is to switch the jumper back.
It may take a while until the new version of U-Boot shows up on the
CVS server; the patch against U-Boot version 1.0.0 is also available
