-- DataFlash Support:
- CONFIG_HAS_DATAFLASH
-
- Defining this option enables DataFlash features and
- allows to read/write in Dataflash via the standard
- commands cp, md...
-
- Serial Flash support
Usage requires an initial 'sf probe' to define the serial
flash parameters, followed by read/write/erase/update
