I'm having no trouble with kernel and world on two CN5020 boards and
no trouble with starting the kernel on a CN5860-based board.  The
CN5860 board has problems I'm dealing with.

That said, the two CN5020 boards are running with this patch to
U-Boot, which I really did find was necessary because the address the
(unused) data was stored at conflicts with the per-CPU storage area,
IIRC.

I have a more conservative ldscript that I can check in and move the
Octeon kernel configurations to, which gets rid of the non-executable
program headers that generate messages.  All that really matters is
that we not have multiple executable program headers because that
completely breaks the Octeon ELF loading code.
