[codekipper at gmail.com <codekipper@gmail.com>]

From: Marcus Cooper <codekipper@gmail.com>

The Beelink X2 is an STB based on the Allwinner H3 SoC with a uSD slot,
2 USB ports( 1 * USB-2 Host, 1 USB OTG), a 10/100M ethernet port using the
SoC's integrated PHY, Wifi via an sdio wifi chip, HDMI, an IR receiver, a
dual colour LED and an optical S/PDIF connector.
