config SAMA5D4EK_DRAM_MAIN
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_DRAM_BOOT
bool "Using DRAM boot loader"
default y
depends on SAMA5_BOOT_SDRAM && !SAMA5D4EK_DRAM_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_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.

be no wear-leveling.
