Well, I was hoping to get more detailed suggestions from folks here,
now that we know it is not board specific and probably breaks a lot
of the older freescale boards - both the sbc8548 and sbc8641d were
close derivatives of their MPC8548CDS and HPCNET/8641D cousins, but
just targeting a smaller form factor.  I'm betting they are dead too.

Maybe now that we know that, Simon [added to CC] can offer some more
detailed suggestions on what is going on, since I bisected it back
to his commit relating to uart init.

I can test incremental changes on top of that last working baseline
easily enough, since the board has redundant flash (which let me
get that far).  But currently I've no clue where to start, since
the uart init breaking net init, or leaving a booby-trap such that
touching the net device hangs - doesn't really point to an obvious
starting point to test.  :(

Paul.
