Hi,

> Thanks for fixing the OMAP4 compilation issues. We need below patch to make the kernel boot on OMAP4430 on the latest LO master.

No problem. In the future, let's make sure the omap4 patches are merged
into l-o master branch for testing. This time the first three patches
in the omap-fixes branch were build breakage caused by the omap4 patches
directly or indirectly..

Also, please everybody check that your patches don't break the build
for other the omaps, and also boot test on some other omaps if someting
looks risky.

Few comments below.

The opps probably should be oops above :)

Can't we fix the extra uart instead of removing it? We just added it!
It's still there in omap4, right?
