The Armada 3700 integrates the following interfaces (not complete list): - Dual Cortex-A53 ARMv8 - USB 3.0 - SATA 3.0 - PCIe 2.0 - 2 x Gigabit Ethernet 1Gbps / 2.5Gbps - ... This patch adds basic support for this ARMv8 based SoC into U-Boot. Future patches will integrate other device drivers and board support for the Marvell DB-88F3720 development board.
