9		* Big: dual-core Cortex-A72
10		* Little: quad-core Cortex-A53
11		* IRAM: 200KB
12	* DRAM: 4GB-128MB dual-channel
13	* eMMC: onboard eMMC
14	* SD/MMC
15	* GbE (onboard Micrel KSZ9031) Gigabit ethernet PHY
16	* USB:
17		* USB3.0 dual role port

19	* Display: HDMI/eDP/MIPI
20	* Camera: 2x CSI (one on the edge connector, one on the Q7 specified CSI ZIF)
21	* NOR Flash: onboard SPI NOR
22	* Companion Controller: onboard additional Cortex-M0 microcontroller
23		* RTC
24		* fan controller
25		* CAN

27Here is the step-by-step to boot to U-Boot on rk3399.
28
29Get the Source and build ATF/Cortex-M0 binaries
30===============================================
31
32  > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
33  > git clone git://git.theobroma-systems.com/rk3399-cortex-m0.git
34
35Compile the ATF
36===============
37
38  > cd arm-trusted-firmware
39  > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
40  > cp build/rk3399/release/bl31.bin ../u-boot/bl31-rk3399.bin
41
42Compile the M0 firmware
43=======================
44
45  > cd ../rk3399-cortex-m0
46  > make CROSS_COMPILE=arm-cortex_m0-eabi-
47  > cp rk3399m0.bin ../u-boot
48
49Compile the U-Boot
50==================
51
52  > cd ../u-boot
53  > make CROSS_COMPILE=aarch64-linux-gnu- puma-rk3399_defconfig all
54
55Package the image
56=================
57
58Creating a SPL image for SD-Card/eMMC
59  > tools/mkimage -n rk3399 -T rksd -d spl/u-boot-spl.bin spl_mmc.img
60Creating a SPL image for SPI-NOR
61  > tools/mkimage -n rk3399 -T rkspi -d spl/u-boot-spl.bin spl_nor.img
62Create the FIT image containing U-Boot proper, ATF, M0 Firmware, devicetree
63  > make CROSS_COMPILE=aarch64-linux-gnu- u-boot.itb
64
65Flash the image
66===============
67
68Copy the SPL to offset 32k for SD/eMMC, offset 0 for NOR-Flash and the FIT
69image to offset 256k card.
70
71SD-Card
72-------
73
74  > dd if=spl_mmc.img of=/dev/sdb seek=64
75  > dd if=u-boot.itb of=/dev/sdb seek=512
76
77eMMC
78----
79
80rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
81help of the Rockchip loader binary.
82
83  > git clone https://github.com/rockchip-linux/rkdeveloptool
84  > cd rkdeveloptool
85  > autoreconf -i && ./configure && make
86  > git clone https://github.com/rockchip-linux/rkbin.git
87  > ./rkdeveloptool db rkbin/rk33/rk3399_loader_v1.08.106.bin
88  > ./rkdeveloptool wl 64 ../spl_mmc.img
89  > ./rkdeveloptool wl 512 ../u-boot.itb
90
91NOR-Flash
92---------
93
94Writing the SPI NOR Flash requires a running U-Boot. For the sake of simplicity
95we assume you have a SD-Card with a partition containing the required files
96ready.
97
98  > load mmc 1:1 ${kernel_addr_r} spl_nor.img
99  > sf probe
100  > sf erase 0 +$filesize
101  > sf write $kernel_addr_r 0 ${filesize}
102  > load mmc 1:1 ${kernel_addr_r} u-boot.itb
103  > sf erase 0x40000 +$filesize
104  > sf write $kernel_addr_r 0x40000 ${filesize}
105
106
107Reboot the system and you should see a U-Boot console on UART0 (115200n8).
