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. This is code is cleaned-up version of code I did last month that is already used by some people: https://github.com/hallor/u-boot Signed-off-by: Mateusz Kulikowski <mateusz.kulikowski@gmail.com> --- arch/arm/dts/Makefile | 2 + arch/arm/dts/dragonboard410c.dts | 157 +++++++++++++++++++ arch/arm/mach-snapdragon/Kconfig | 9 ++ board/qualcomm/dragonboard410c/Kconfig | 15 ++ board/qualcomm/dragonboard410c/Makefile | 8 + board/qualcomm/dragonboard410c/dragonboard410c.c | 111 ++++++++++++++ board/qualcomm/dragonboard410c/head.S | 20 +++ board/qualcomm/dragonboard410c/readme.txt | 40 +++++ board/qualcomm/dragonboard410c/u-boot.lds | 90 +++++++++++ configs/dragonboard410c_defconfig | 29 ++++ include/configs/dragonboard410c.h | 184 +++++++++++++++++++++++ 11 files changed, 665 insertions(+) create mode 100644 arch/arm/dts/dragonboard410c.dts create mode 100644 board/qualcomm/dragonboard410c/Kconfig create mode 100644 board/qualcomm/dragonboard410c/Makefile create mode 100644 board/qualcomm/dragonboard410c/dragonboard410c.c create mode 100644 board/qualcomm/dragonboard410c/head.S create mode 100644 board/qualcomm/dragonboard410c/readme.txt create mode 100644 board/qualcomm/dragonboard410c/u-boot.lds create mode 100644 configs/dragonboard410c_defconfig create mode 100644 include/configs/dragonboard410c.h
