	bool "Build dram_main"
	default n
	depends on SAMA5_BOOT_ISRAM
	---help---
		dram_main is a tiny program that runs in ISRAM.  dram_main will
		enable SDRAM and load an Intel HEX program into SDRAM over the
		serial console. Then it will either (1) jump to the program in
		DRAM at address 0x2000:0000 (2) wait for you to break in with GDB to
		debug the SDRAM program.  These different behaviors are controlled
		by SAMA5D4EK_DRAM_START.

		NOTE: If you use this boot loader, then your program must be built at
		origin 0x2000:0000, not at 0x2000:8000 as is customary with U-Boot.

config SAMA5D4EK_DRAM_START
	bool "Start DRAM program"
	default n
	depends on SAMA5D4EK_DRAM_MAIN
	---help---
		The default behavior of the DRAM boot program is to initialize the
		DRAM, then patiently wait for you to break into the program with GDB.
		An alternative behavior is enabled with this option:  If
		SAMA5D4EK_DRAM_START is defined, then it will not wait but will,
		instead, immediately start the program in DRAM.

config SAMA5D4EK_AT25_MAIN
	bool "Build at25_main"
	default n
	depends on SAMA5_BOOT_ISRAM
	---help---
		at25_main is a tiny program that runs in ISRAM.  at25_main will
		enable SDRAM and configure the AT25 Serial FLASH.  It will prompt
		and then load an Intel HEX program into SDRAM over the serial
		console. If the program is successfully loaded in SDRAM, at25_main
		will copy the program at the beginning of the AT26 Serial FLASH.
		If the jumpering is set correctly, the SAMA5D4 RomBOOT loader will
		then boot the program from the serial FLASH the next time that it
		reset.

config SAMA5D4EK_AT25_PROGSIZE
	int "AT25 partition size"
	default 131072
	depends on SAMA5D4EK_AT25_MAIN
	---help---
		This is the size of the partition at the beginning to the AT25
		serial FLASH that will be used to hold the boot program.  Since
		this program must run from SRAM, there would be no purpose int
		making this size any larger than the size of the internal SRAM.

config SAMA5D4EK_DRAM_BOOT
	bool "Using DRAM boot loader"
	default y
	depends on SAMA5_BOOT_SDRAM && !SAMA5D4EK_DRAM_MAIN && !SAMA5D4EK_AT25_MAIN
	---help---
		Select this option if you are going to boot using the sdram_main
		bootloader (created with SAMA5D4EK_DRAM_MAIN=y).  This selection
		will simply origin your program at 0x2000:0000 as required by the
		sdram_main bootloader (vs. 0x2000:8000 as required by U-Boot).

config SAMA5D4EK_NAND_AUTOMOUNT
	bool "NAND FLASH auto-mount"
	default n
	depends on NSH_ARCHINIT && SAMA5_EBICS3_NAND
	---help---
		Automatically initialize the NAND FLASH driver when NSH starts.

config SAMA5D4EK_NAND_FTL
	bool "Create NAND FLASH block driver"
	depends on MTD && MTD_NAND
	---help---
		Create the MTD driver for the NAND and "wrap" the NAND as a standard
		block driver that could then, for example, be mounted using FAT or
		any other file system.  Any file system may be used, but there will
		be no wear-leveling.

		NOTE: This options is not currently recommended.  There is not now
		NuttX file system that can handle the NAND back blocks or performs
		wear-leveling other than NXFFS and NXFFS does not use a block driver
		but, rather, operates directly upon the NAND MTD device.

config SAMA5D4EK_NAND_NXFFS
	bool "Create NAND FLASH NXFFS file system"
	depends on MTD && MTD_NAND && FS_NXFFS && NXFFS_NAND
	---help---
		Create the MTD driver for the NAND and mount the NAND device as
		a wear-leveling, NuttX FLASH file system (NXFFS).  The downside of
		NXFFS is that it can be very slow.

		NOTE: NXFFS is recommended because (1) it can handle the NAND back
		blocks and (1) performs wear-leveling.
