+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:

Therefore RK3288 has another loading sequence like RK3036. The option of
U-Boot is controlled with this setting in U-Boot:
- #define CONFIG_ROCKCHIP_SPL_BACK_TO_BROM
+ #define CONFIG_SPL_ROCKCHIP_BACK_TO_BROM
You can create the image via the following operations:

+RK3368 dynamic memory controller driver
+=======================================
+
+The RK3368 DMC (dynamic memory controller) driver supports setup/initialisation
+during TPL using configuration data from the DTS (i.e. OF_PLATDATA), based on
+the following key configuration data:
+ (a) a target-frequency (i.e. operating point) for the memory operation
+ (b) a speed-bin (as defined in JESD-79) for the DDR3 used in hardware
+ (c) a memory-schedule (i.e. mapping from physical addresses to the address
+ pins of the memory bus)
+

+ For very constrained SPL environments the overhead of decoding

+ is too large. This overhead includes libfdt code as well as the
+ device tree contents itself. The latter is fairly compact, but the
+ former can add 3KB or more to a Thumb 2 Image.
+

+ declarations. The benefit is that it allows driver code to access
+ the platform data directly in C structures, avoidin the libfdt
+ overhead.
+
+ This option works by generating C structure declarations for each
