The mtd-utils package provides NAND and SPI flash capabilities for mainline kernel /dev/mtdX devices. This will help on board setup from SD card boot.

closes #4427

Description

The mtd-utils package provides tools for flashing the boards NAND and/or SPI flash chips. In the meanwhile most NAND and SPI chips are supported by mainline kernel MTD drivers. Boards like Cubietruck or Odroid M1 can boot from NAND or SPI with mainline U-Boot. The according flash chips can be flashed with the mtd-utils tools from the mainline kernel booted OS after an initial Armbian SD card boot. This simplifies board setup or boards boot loader update to enable booting from the on board soldered flash memory.

Refers to issue #4427.
