With that patch I have a working serial again.
I added a new flag used for both XSCALE and TEGRA port types, and
modified the XSCALE port type to define the new flag, thinking that all
code would take the capabilities from that port type table entry, but
perhaps the auto-detection logic needs an equivalent change for XSCALE.
I'm little worried that it seems somehow that I have two uarts at
0xdffe0200 and IRQ4 which is evil.
That does sound odd. It's very unclear to me how my change would cause
that...
Seems unrelated to your change.
