[ARM PATCH] 1670/1: PXA serial driver
Patch from Holger Schurig
PXA Serial port (FFUART, BTUART, STUART) and console support
This patch works perfectly here with "console=ttyS0,115200" in the
kernel command line. It contains Jean-frederic Clere fix to detect
STUART and BTUART.
Nico said that I should post it to your patch tracker. It replaces patch 1662/1
