All 32-bit Armada SoCs and also 64-bit Armada 3720 SoC can load and boot firmware from SATA disk. This adds support for updating firmware binary for these SoCs. On 32-bit Armada SoC is firmware stored at sector 1 and on Armada 3720 is stored at MBR partition 0x4d or GPT partition with type GUID 6828311A-BA55-42A4-BCDE-A89BB5EDECAE (Marvell Armada 3700 Boot partition).
