On the support side, I'm not looking forward to this for beagle/panda
users.  We've already converted them once from ttySx -> ttyOx back in
2.6.33/2.6.34? days.  That was an irc/email/u-boot/kernel nightmare...

that's exactly why we're talking about ways to maintain backwards
compatibility here. But I'm more interested in finding a way to switch
over to ttyS and have a symlink to ttyO, that way a simple debootstrap
(or any other ARM distro minimal rootfs) would work out of the box,
without any changes, just like in "normal" systems.

Yeah let's not break things. The symlink solution won't work for kernel

again. Let's not break things again.

console output so it needs to be dealt with some other way.

it would if kernel itself would create the symlink, but that might not
be doable in a clean way.

It seems that the biggest amount of work is making existing 8250
support the missing features in a clean way and without breaking
other platforms. Looks like 8250_dw.c has some pm_runtime_calls so
obviously it's doable.

right
