== How to find the Silicon Revision of your OMAP35x/DM37x ==
Read back a 32 bit word from the CONTROL_IDCODE Register at address: 0x4830 A204
from the read back value: 0x4B7AE02F, you can see the revision of this OMAP35x corresponds to ES3.1
== How to check system boot order ==  # devmem2 0x480022F0 b == How to find the SGX core revision of your OMAP35x/AM35x/37x ==
Perform the following commands on the target with an utility like devmem2.

== How to get the processor DIEID ==
#!/bin/sh
DIEID=""
for addr in '0x4830a224' '0x4830a220' '0x4830a21c' '0x4830a218'; do
DIEID=${DIEID}`devmem2 0x4830a224 $addr | awk '/Read/ { printf "%08X", $6 }'`
done
echo ${DIEID}

Conclusion: No big difference with this test.
== NAND/OneNAND ==
We assume that the mtd4 is available for test.
