board: Add Qualcomm Dragonboard 410C support
This commit add support for 96Boards Dragonboard410C. It is board based on APQ8016 Qualcomm SoC, complying with 96boards specification. Features (present out of the box): - 4x Cortex A53 (ARMv8) - 2x USB Host port - 1x USB Device port - 4x LEDs - 1x HDMI connector - 1x uSD connector - 3x buttons (Power, Vol+, Vol-/Reset) - WIFI, Bluetooth with integrated antenna - 8GiB eMMC U-Boot boots chained with fastboot in 64-bit mode. For detailed build instructions see readme.txt in board directory. Signed-off-by: Mateusz Kulikowski <mateusz.kulikowski@gmail.com> Tested-by: Simon Glass <sjg@chromium.org>
