On our devices, the U-Boot environment is the only place the ethernet
MAC address is stored.

Since the infrastructure for passing environment variables up to the
MIPS Linux kernel existed anyways, I decided that it would be a better
plan to use that machanism than to have the kernel dig through the
duplicate U-Boot environments.

I don't consider this patch a "must have" for upstream. I try to make
sure all the changes that are needed for our product are sent to the
u-boot list, even if they don't end up being accepted for DENX's U-Boot.

On a completely unrelated topic, I really like the MIPS 'environment'
method of passing information to the kernel instead of the old 'bd_t'
method. It's a lot more flexible.
