How to find the Silicon Revision of your OMAP35x

Read back a 32 bit word from the CONTROL_IDCODE Register at address: 0x4830 A204

Silicon Revision 32-bit readback value
ES1.0 0x0B6D 602F
ES2.0 0x1B7A E02F
ES2.1 0x2B7A E02F
ES3.0 0x3B7A E02F
ES3.1 0x4B7A E02F

Use the memory dump capability of u-boot: 

U-Boot # md 0x4830A204 1
