Hi Beleswar,

It's fine to enable drivers that are only used on a specific
platform, but those should generally be loadable modules, not
built-in.

For the generic (platform-independent) options, I would
suggest splitting them out into a separate patch, so you
can describe better what the purpose is, since this is
clearly not just for OMAP.

This one seems particularly unnecessary in a "defconfig" build
since the configuration is already known based on the version.

The documentation for this option suggests that we probably
don't want it enabled.

I assume these are all in order to run a particular userspace
distro?
