Klaus Goger a13110a99f rockchip: ARM64: split RK3399-Q7 board off the RK3399-EVB board
The RK3399-Q7 SoM is a Qseven-compatible (70mm x 70mm, MXM-230
connector) system-on-module from Theobroma Systems, featuring the
Rockchip RK3399.

It provides the following feature set:
 * up to 4GB DDR3
 * on-module SPI-NOR flash
 * on-module eMMC (with 8-bit interace)
 * SD card (on a baseboad) via edge connector
 * Gigabit Ethernet w/ on-module Micrel KSZ9031 GbE PHY
 * HDMI/eDP/MIPI displays
 * 2x MIPI-CSI
 * USB
   - 1x USB 3.0 dual-role (direct connection)
   - 2x USB 3.0 host + 1x USB 2.0 (on-module USB 3.0 hub)
 * on-module STM32 Cortex-M0 companion controller, implementing:
   - low-power RTC functionality (ISL1208 emulation)
   - fan controller (AMC6821 emulation)
   - USB<->CAN bridge controller

Note that we use a multi-payload FIT image for booting and have
Cortex-M0 payload in a separate subimage: we thus rely on the FIT
image loader to put it into the SRAM region that ATF expects it in.
