[U-Boot] [PATCH] sunxi: Add support for Cubietruck Plus

[Chen-Yu Tsai]

Cubietruck Plus is a A83T/H8 based development board. The board has
standard DDR3 SDRAM, AXP818 PMIC/codec, SD/MMC, eMMC, USB 2.0 host
via HSIC USB Hub, USB OTG, SATA via USB bridge, gigabit ethernet,
WiFi, headphone out / mic in, and various GPIO headers.

The board also has an EEPROM on i2c0 which holds the MAC address.

DLDO3 and DLDO4 provide power to the EMAC pins and PHY. Pin PA20
is connected to the reset control of the PHY. EMAC is not actually
supported yet.

The DTS is the same as the one already in the kernel.
