3.4.7.3 ConfigID hardware implementation on BORA/BORAX
BORA/BORAX uses the first 32bytes OTP block on NOR SPI to
store ConfigID (and its CRC32), UniqueID (and its CRC32)
3.4.7.4 ConfigID software implementation on BORA/BORAX
U-Boot integrates the software routines for reading and
displaying the ConfigID. Hereunder an example of SOM
