You need to edit the file linux-2.4.x/include/asm-microblaze/xparameters.h

It's essentially the xparameters.h file generated by EDK, with a few
tweaks.  It should be obvious how to change it for what you need.  You
will then need to recompile the kernel for your changes to take effect.

It sounds ridiculous, but if you don't have your kernel build
environment going yet it might be easier to change the hardware (MHS) to
fit the kernel, rather than the other way around!

Regards,

John
