config MTD_PARTITION
	bool "Support MTD partitions"
	default n
	---help---
		MTD partitions are build as MTD drivers that manage a sub-region
		of the FLASH memory.  The contain the original FLASH MTD driver and
		simply manage all accesses to assure that (1) FLASH accesses are
		always offset to the beginning of the partition, and (2) that FLASH
		accesses do not extend outside of the partition.

		A FLASH device may be broken up into several partitions managed,
		each managed by a separate MTD driver.  The MTD parition interface
		is described in:

			include/nuttx/mtd.h
			FAR struct mtd_dev_s *mtd_partition(FAR struct mtd_dev_s *mtd, off_t offset, off_t nblocks);

		Each call to mtd_partition() will create a new MTD driver instance
		managing the sub-region of flash beginning at 'offset' (in blocks)
		and of size 'nblocks' on the device specified by 'mtd'.

		International MX25 serial FLASH, the correct manufacturer ID would be 0xc2.
