This you should also send to linux-arm-kernel list.
Should the comment above be changed to ARMv7 from "new CPU Id"?

OK, I will post them after getting it on OMAP GIT.

I have to revisit this file as merge from ARM GIT has broken kernel based Un-compressing for ARMV7. I will think about proper comment along with this.

Please discard this patch. I found these changes were actually not required to get kernel booting on OMAP3430.
Please consider the one posted before this (today).
