I decided to play with my snowball board as that's the easiest arm
board I have to do testing on, and it was reported to me that I broke
function graph tracing on the arm boards. But I haven't booted my
snowball since 3.8. When I tried with the latest kernel, it didn't give
me *any* output. I figured something was up with the uart, but the
board also didn't boot.
I did a bisect to find out where the uart stopped working (I also
stumbled on where the board stopped booting, but still need to find
that commit). The uart died with this commit:

ARM: ux500: Remove UART support when booting without Device Tree
It's time to remove all ATAG support from ux500 and rely solely on
Device Tree booting. This patch is part of that endeavour.

This happened between 3.12 and 3.13.
Does this mean that I need to get device tree support for this. I have
no idea how to fix it as a device tree to me is a christmas tree (a
tree with little lighty devices on it). Thus I'll just go and throw
this out at you.
Thanks,
