Access u-boot environment variables from Linux

Dear Wolfgang,

Yes, but our final target will use 0x0003FF00, so we can have more
space. We are making our target as compatible as possible to the
TQM860L.

Yes. I didn't know of it. It was absent in ppc-boot, and _reading_ the
change log from version to version may solve this...

Perhaps, and probably, you are right. I will re-check/re-think. It looks
easier to make changes on the SELF scripts. And it can be used on Linux
version that do not support the ELDK rebuild from scratch.

Anyway, my original problem is solved :) . I use the /tools/env, and
perhaps later the MTD patch.

Thanks,
Eli Brin
