   1 Introduction
   2 ============
   3
   4 RK3399 key features we might use in U-Boot:
   5 * CPU: ARMv8 64bit Big-Little architecture,
   6 *      Big: dual-core Cortex-A72
   7 *      Little: quad-core Cortex-A53
   8 * IRAM: 200KB
   9 * DRAM: 4GB-128MB dual-channel
  10 * eMMC: support eMMC 5.0/5.1, suport HS400, HS200, DDR50
  11 * SD/MMC: support SD 3.0, MMC 4.51
  12 * USB: USB3.0 typc-C port *2 with dwc3 controller
  13 *      USB2.0 EHCI host port *2
  14 * Display: RGB/HDMI/DP/MIPI/EDP
  15
  16 evb key features:
  17 * regulator: pwm regulator for CPU B/L
  18 * PMIC: rk808
  19 * debug console: UART2
  20
  21 In order to support Arm Trust Firmware(ATF), we need to use the
  22 miniloader from rockchip which:
  23 * do DRAM init
  24 * load and verify ATF image
  25 * load and verify U-Boot image
  26
  27 Here is the step-by-step to boot to U-Boot on rk3399.
  28
  29 Get the Source and prebuild binary
  30 ==================================
  31
  32   > mkdir ~/evb_rk3399
  33   > cd ~/evb_rk3399
  34   > git clone https://github.com/ARM-software/arm-trusted-firmware.git
  35   > git clone https://github.com/rockchip-linux/rkbin
  36   > git clone https://github.com/rockchip-linux/rkflashtool
  37
  38 Compile the ATF
  39 ===============
  40
  41   > cd arm-trusted-firmware
  42   > make realclean
  43   > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3399 bl31
  44
  45 Compile the U-Boot
  46 ==================
  47
  48   > cd ../u-boot
  49   > make CROSS_COMPILE=aarch64-linux-gnu- evb-rk3399_defconfig all
  50
  51 Compile the rkflashtool
  52 =======================
  53
  54   > cd ../rkflashtool
  55   > make
  56
  57 Package the image for miniloader
  58 ================================
  59   > cd ..
  60   > cp arm-trusted-firmware/build/rk3399/release/bl31.bin rkbin/rk33
  61   > ./rkbin/tools/trust_merger rkbin/tools/RK3399TRUST.ini
  62   > ./rkbin/tools/loaderimage --pack --uboot u-boot/u-boot-dtb.bin uboot.img
  63   > mkdir image
  64   > mv trust.img ./image/
  65   > mv uboot.img ./image/rk3399evb-uboot.bin
  66
  67 Flash the image
  68 ===============
  69 Power on(or reset with RESET KEY) with MASKROM KEY preesed, and then:
  70
  71   > ./rkflashtool/rkflashloader rk3399evb
  72
  73 You should be able to get U-Boot log message in console/UART2 now.
