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.

Introduction
============
The RK3399-Q7 (Puma) is a system-on-module featuring the Rockchip
RK3399 in a Qseven-compatible form-factor.
RK3399-Q7 features:
* CPU: ARMv8 64bit Big-Little architecture,
* Big: dual-core Cortex-A72
* Little: quad-core Cortex-A53
* IRAM: 200KB
* DRAM: 4GB-128MB dual-channel
* eMMC: onboard eMMC
* SD/MMC
* GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY
* USB:
* USB3.0 dual role port
* 2x USB3.0 host, 1x USB2.0 host via onboard USB3.0 hub
* Display: HDMI/eDP/MIPI
* Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF)
* NOR Flash: onboard SPI NOR
* Companion Controller: onboard additional Cortex-M0 microcontroller
* RTC
* fan controller
* CAN
Here is the step-by-step to boot to U-Boot on rk3399.
Get the Source and build ATF/Cortex-M0 binaries
===============================================
> git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
> git clone git://git.theobroma-systems.com/rk3399-cortex-m0.git
Compile the ATF
===============
> cd arm-trusted-firmware
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
> cp build/rk3399/release/bl31.bin ../u-boot
Compile the M0 firmware
=======================
> cd ../rk3399-cortex-m0
> make CROSS_COMPILE=arm-cortex_m0-eabi-
> cp rk3399m0.bin ../u-boot
Compile the U-Boot
==================
> cd ../u-boot
> make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all
Package the image
=================
> tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl.img
> tools/mkimage -f board/theobroma/puma_rk3399/fit_spl_atf.its \
-E rk3399_bl3x.itb
Flash the image
===============
Copy the SPL to offset 32k and the FIT image containing the payloads
(U-Boot proper, ATF, M0 Firmware, devicetree) to offset 256k on a SD
card.
> dd if=spl.img of=/dev/sdb seek=64
> dd if=rk3399_bl3x.itb of=/dev/sdb seek=512
After powering up the board (with the inserted SD card), you should see
a U-Boot console on UART0 (115200n8).
