21 * The Allwinner H3 is a System on Chip containing four ARM Cortex A7
22 * processor cores. Features and specifications include DDR2/DDR3 memory,
23 * SD/MMC storage cards, 10/100/1000Mbit Ethernet, USB 2.0, HDMI and
24 * various I/O modules.
26 * This implementation is based on the following datasheet:
28 * https://linux-sunxi.org/File:Allwinner_H3_Datasheet_V1.2.pdf
30 * The latest datasheet and more info can be found on the Linux Sunxi wiki:
