Detect which Overo

To determine if the Gumstix COM has an OMAP3503 processor or an OMAP3530 processor, look for the following information in the boot-up message:

"OMAP3503-GP rev 2, CPU-OPP2 L3-165MHz" implies OMAP3503 (Overo Earth and Overo Air)

whereas the message:

"OMAP3530-GP rev 2, CPU-OPP2 L3-165MHz" implies OMAP3530 (Overo Water and Overo Fire).

All u-boots after Tuesday, February 3 2009 have the proper CPU detection.

u-boot dated prior to February 3rd, 2009 does not have proper CPU detection so a u-boot update may be needed to obtain this information.
