Notes: 
1.
Fixed feature due to the SOM internal connection.
2.
Limited feature compared to SAMA5D2 due to the SOM internal use of specific functionality, for example,
QSPI, GMAC.
3.
Limited feature compared to SAMA5D2 due to the use of a part of the functionality for other features in the
SOM, for example, GMAC, ISC, Flexcom, etc.
