   1 This document describes the instruction to build and flash ATF/OPTEE/U-Boot on
   2 pico-imx7d board. U-Boot is loaded as part of FIP image by ATF in this setup.
   3 The boot sequence is ATF -> OPTEE -> U-Boot -> Linux. U-Boot is in non-secure
   4 world in this case.
   5
   6 - Build u-boot
   7     Set environment variable of CROSS_COMPILE for your toolchain
   8     $ make pico-imx7d_bl33_defconfig
   9     $ make all
  10
  11 - Download and build OPTEE
  12     $ git clone git@github.com:OP-TEE/optee_os.git
  13     $ make PLATFORM=imx PLATFORM_FLAVOR=mx7dpico_mbl CFG_BOOT_SECONDARY_REQUEST=y ARCH=arm
  14
  15 - Download and build ATF
  16     $ git clone https://git.linaro.org/landing-teams/working/mbl/arm-trusted-firmware.git -b linaro-imx7
  17     $ make DEBUG=1 PLAT=picopi ARCH=aarch32 ARM_ARCH_MAJOR=7 \
  18             CROSS_COMPILE=arm-linux-gnueabihf- LOG_LEVEL=50 V=1 \
  19             CRASH_REPORTING=1 AARCH32_SP=optee all

  22     $ u-boot/tools/mkimage -n pico-imx7d.cfg -T imximage -e 0x9df00000 -d \
  23             build/picopi/debug/bl2.bin bl2.imx
  24
  25 - Create FIP image
  26     Create a  fiptool_images/ folder in ATF folder, copy u-boot.bin in u-boot
  27 folder and tee*.bin in optee out/arm-plat-imx/core/tee/ folder to
  28 fiptool_images. Run below command in ATF folder to generate FIP image.
  29     $ make -C tools/fiptool/
  30     $ tools/fiptool/fiptool create --tos-fw fiptool_images/tee-header_v2.bin \
  31           --tos-fw-extra1 fiptool_images/tee-pager_v2.bin \
  32           --tos-fw-extra2 fiptool_images/tee-pageable_v2.bin \
  33           --nt-fw fiptool_images/u-boot.bin \
  34           fip.bin
  35
  36 - Burn the images to eMMC for test.
  37     Run below command in atf folder:
  38     $ dd if=build/picopi/debug/bl2.bin.imx of=/dev/disk/by-id/usb-<your device>  bs=1024 seek=1;sync
  39     $ dd if=fip.bin of=/dev/disk/by-id/usb-<your device>  bs=1024 seek=1;sync
  40
  41 - Test
  42     Just boot up your board and wait for u-boot start up after ATF's log.
  43     For booting Linux in FIT image, please reference the FIT files in
  44     u-boot doc/uImage.FIT/ folder.
