From: Klaus Goger <klaus.goger at theobroma-systems.com>
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.

Changes in v2:
- fixes dram_init_banksize() to have the correct return type and to
return 0 (success) unconditionally

+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).
