is not available in the kernel build.

The default is to use the RAM MTD device at drivers/mtd/rammtd.c.

But an architecture-specific MTD driver can be used instead by

defining EXAMPLES_MTDRWB_ARCHINIT. In this case, the

initialization logic will call mtdrwb_archinitialize() to obtain

the MTD driver instance.
