[U-Boot-Users] Problems with u-boot, PPChameleonEVB and MontaVista kernel

Hi again Andy,
At least this time I read your question more thoroughly :)

We are becoming off-topic for the U-Boot list -- if you want to take
this further, switch to the linuxppc list.

I can tell you for a start that you will need to customize your Linux
.config file (make menuconfig for example) for your particular target,
and you will also want to study the platform-specific code under
arch/ppc/platforms.  If your target is not currently supported, you
will need to create that support.  That means *at least* the files under 
arch/ppc/platforms, and the Makefile and Config.in changes needed
in the tree to support selection of the new platform and its features.

I encourage you to do a search of the entire Linux tree (not case 
sensitive) for a word like "walnut":

  find . -type f |xargs grep -i walnut

This will give you a feel for the places that platform-specifics
pop up.

Hope that helps,
Chuck
