Enables the MCUX flash shim driver.
WARNING: This driver will disable the system interrupts for
the duration of the flash erase/write operations. This will
have an impact on the overall system performance - whether
this is acceptable or not will depend on the use case.

help
Do a margin check flash command before reading an area.
This feature prevents erroneous/forbidden reading. Some ECC enabled
devices will crash when reading an erased or wrongly programmed area.

Copy the data to a RAM buffer before writing it to the flash.
This prevents faults when the data to write would be located on the
flash itself.
