Broke a whole lot of tegra boards in last night's -next here. In
particular, I've been looking at tegra20-seaboard, which now doesn't
boot with console any more.

Unfortunately, tegra has for a long time been specifying the aliases
as a fixed 1:1 mapping, but most environments rely on ttyS0 being the
first _activated_ serial port. That's obviously going to break things
here. :(

Stephen: I suppose the best way to handle this on tegra is to specify
the aliases per-board instead of in the soc dtsi today.
IIRC, there was a deliberate request to name the Tegra UARTs after the
SoC ports rather than board ports, so that it'd be obvious to people
which port was which. I'm not sure if we can change the aliases in the
Tegra DTs now that people may have got used to them?
