probably need ES_1_1, 1_2 (considering 3630)


This should be okay, since the 3630 is out with
these revisions, but...

makes sense to go to 2_2

3_2?

This may not make sense to add now as there are no
2.2 or 3.2 revisions of any OMAP3/4 silicon?

Agreed for 3 and 4, but considering this is arch/arm/plat-omap/include/plat/cpu.h, does it make sense in looking all OMAPs?
