From: Carl-Johan Irekvist <carl-johan.irekvist@stericsson.com>
The uncompress code for zImage uses the UART to print status messages,
this was hard coded to use UART2 for the U8500 platform. This patch
checks at run time which platform it is run on. U5500 uses UART0 as
console UART.

I've picked patches 1 thru 4 in this patch set to ux500-core and
-next testing, need 5 thru 9 to be rebased, maybe I will be able to
do that maybe not (#5 looks hairy, I could use some help).

Russell,
this and subsequent patches from Rabin require the GIC patches from
your tree. So if I try to prep platform cleanups on top of this I depend
on them...
Since I plan to issue a pull request for the ux500 platform what
would be the best way to get out of this?
I seem to remember you don't like to pull code based off your
internal branches.
I'm contemplating cherry-picking the GIC patches (and any deps)
from your tree, basing my pullable tag on that and letting git cope.
Sounds OK?
Yours,
Linus Walleij
