commit 745fd2106df5ed950e1ab05768fc2e14e6fdface Author: Ronald G. Minnich rminnich@gmail.com Date: Wed Feb 20 14:13:01 2013 -0800
ARMV7: create a correct LB_SERIAL table entry
If CONFIG_CONSOLE_SERIAL is set, and we can call the standard function and get a non-zero uart address, then we create an lb table entry.
The code was mostly right, just needed a tweak.
