config EXAMPLES_MTDRWB
	tristate "MTD R/W buffer test"
	default n
	depends on (MTD_WRBUFFER || MTD_READAHEAD) && BUILD_FLAT
	select BCH
	---help---
		Enable the MTD R/W buffer test example.

		NOTE: This example uses some internal NuttX interfaces and, hence,
		is not available in the kernel build.

if EXAMPLES_MTDRWB

config EXAMPLES_MTDRWB_PROGNAME
	string "Program name"
	default "mtdrwb"
	---help---
		This is the name of the program that will be used when the NSH ELF
		program is installed.

config EXAMPLES_MTDRWB_ARCHINIT
	bool "Architecture-specific initialization"
	default n
	---help---
		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.

if !EXAMPLES_MTDRWB_ARCHINIT

config EXAMPLES_MTDRWB_ERASESIZE
	int "Size of one erase blocks (simulated)"
	default 4096
	depends on !EXAMPLES_MTDRWB_ARCHINIT
	---help---
		When EXAMPLES_MTDRWB_ARCHINIT is not defined, this test will use
		the RAM MTD device at drivers/mtd/rammtd.c to simulate FLASH.  In
		this case, this value must be provided to give the size of one erase
		simulated erase blocks one MTD RAM device.

		The size of the allocated RAM drive will be:

			EXAMPLES_MTDRWB_ERASESIZE * EXAMPLES_MTDRWB_NEBLOCKS

config EXAMPLES_MTDRWB_NEBLOCKS
	int "Number of erase blocks (simulated)"
	default 32
	depends on !EXAMPLES_MTDRWB_ARCHINIT
	---help---
		When EXAMPLES_MTDRWB_ARCHINIT is not defined, this test will use
		the RAM MTD device at drivers/mtd/rammtd.c to simulate FLASH.  In
		this case, this value must be provided to give the number of erase
		blocks in MTD RAM device.

		The size of the allocated RAM drive will be:

			EXAMPLES_MTDRWB_ERASESIZE * EXAMPLES_MTDRWB_NEBLOCKS
