Access size	32 bits
Byte order	Big Endian

base	function	offset	description	contents/example
0x0D010000	NAND
		0000 W	command	9F000000 (CMD 00: start read sector)
				8030B840 (CMD 30: data (starts DMA 0x840 bytes))
				80FF8000 (CMD FF: reset)
				00008000 means: wait for R/#B to go down
				1F000000 is the mask of the address bytes to send. (10 = AA, 08 = BB, .., 01 = FF in 08,0c)
		0000 R	status	MSB means busy
		0004 W	config
		0008 W	address #0	0000AABB
		000C W	address #1	CCDDEEFF, NAND sector, multiply with 0x800 or 0x840 to get offset, 0x40 for ecc
		0010 W	data addr	target address for DMA (0x800 main bytes)
		0014 W	ecc addr	target address for DMA (0x40 spare bytes + 0x10 byte HW-calculated ECC syndrome)
		0018 W	unknown
