[U-Boot-Users] [PATCH] PPC4xx: Minimal changes to add vxWorks support

Hi

I have to support vxWorks on our boards. In order to avoid changing the TLB
in all PPC440x based boards  I need this small patch. Can it go into the
git repository or do I have to maintain it out of the tree forever?

Best regards
