Amit,

I did some investigation today and found that even upstream Tony's for-next
branch cannot support a single kernel for OMAP2/3/4. I tried to compile it but
building failed. I just built for ARCH_OMAP4, the kernel can boots and serial
port works fine. Hope we can fix this single kernel issue in the future.

So I'm afraid that we can't simply enable OMAP4 in our master branch omap
flavor, since our omap flavor is for OMAP3. In the future, after all the OMAP4
stuff are merged into mainline, we can remove ti-omap4 topic branch but still
need an additional armel flavor - omap4 in master branch.

-Thanks,
