Philipp Tomsich 4d02d20605 rockchip: board: lion-rk3368: add support for the RK3368-uQ7
The RK3368-uQ7 (codenamed 'Lion') is a micro-Qseven (40mm x 70mm,
MXM-230 edge connector compatible with the Qseven specification)
form-factor system-on-module based on the octo-core Rockchip RK3368.
It is designed, supported and manufactured by Theobroma Systems.

It provides the following features:
 - 8x Cortex-A53 (in 2 clusters of 4 cores each)
 - (on-module) up to 4GB of DDR3 memory
 - (on-module) SPI-NOR flash
 - (on-module) eMMC
 - Gigabit Ethernet (with an on-module KSZ9031 PHY)
 - USB
 - HDMI
 - MIPI-DSI/single-channel LVDS (muxed on the 'LVDS-A' pin-group)
 - various 'slow' interfaces (e.g. UART, SPI, I2C, I2S, ...)

Here is the step-by-step to boot to U-Boot on RK3368-uQ7
Get the Source and build ATF
============================
> git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
> cd arm-trusted-firmware
> make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3368 bl31
> cp build/rk3368/release/bl31.bin ../u-boot/bl31-rk3368.bin
Configure U-Boot
================
> cd ../u-boot
> make lion-rk3368_defconfig
Build the TPL/SPL stage
=======================
> make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm
> tools/mkimage -n rk3368 -T rksd -d tpl/u-boot-tpl.bin spl-3368.img
> cat spl/u-boot-spl-dtb.bin >> spl-3368.img
Build the full U-Boot and a FIT image including the ATF
=======================================================
> make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm u-boot.itb
Write to a SD-card
==================
> dd if=spl-3368.img of=/dev/sdb seek=64
> dd if=u-boot.itb of=/dev/sdb seek=512
If everything went according to plan, you should see the following
output on UART0:
<debug_uart> U-Boot TPL board init
