In order to save space on the SPI flash, SquashFS + JFFS2 should be used.

SPI Flash structure

Partition	Content		Offset		Size (byte)
mtd0		uboot-bin	0		0x58000 (360448)
		uboot-env	0x58000		0x8000
mtd1		dtb		0x60000		0x4000  (16kB)
mtd2		kernel		0x64000		0x400000 (4MB)
mtd3 rootfs 0x464000	0x4FC000 (4.98MB)
