[U-Boot] [PATCH] integrator: break out common config
Linus Walleij
linus.walleij at linaro.org
Tue May 22 22:53:19 CEST 2012
The configuration that is common for all Integrator boards may
just as well be stored in a common include file as per pattern
from other boards. This eases maintenance quite a bit.
