-Quick Start
-===========
-
-- Build the ARM Trusted firmware binary
-- Get scfw_tcm.bin and ahab-container.img
-- Get imx-mkimage
-- Build U-Boot
-- Build imx-mkimage
-- Flash the binary into the SD card
-- Boot

-Get and Build the ARM Trusted firmware
-======================================
-
-$ git clone https://source.codeaurora.org/external/imx/imx-atf
-$ cd imx-atf/
-$ git checkout origin/imx_4.14.78_1.0.0_ga -b imx_4.14.78_1.0.0_ga
-$ make PLAT=imx8qm bl31
-
-Get scfw_tcm.bin and ahab-container.img
-==============================
-
-$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-1.1.bin
-$ chmod +x imx-sc-firmware-1.1.bin
-$ ./imx-sc-firmware-1.1.bin
-$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.0.bin
-$ chmod +x firmware-imx-8.0.bin
-$ ./firmware-imx-8.0.bin
-
-Or use this to avoid running random scripts from the internet,
-but note that you must agree to the license the script displays:
-
-$ dd if=imx-sc-firmware-1.1.bin of=imx-sc-firmware-1.1.tar.bz2 bs=37185 skip=1
-$ tar -xf imx-sc-firmware-1.1.tar.bz2
-$ cp imx-sc-firmware-1.1/mx8qm-val-scfw-tcm.bin $(builddir)
-
-$ dd if=firmware-imx-8.0.bin of=firmware-imx-8.0.tar.bz2 bs=37180 skip=1
-$ tar -xf firmware-imx-8.0.tar.bz2
-$ cp firmware-imx-8.0/firmware/seco/mx8qm-ahab-container.img $(builddir)
-
-Build U-Boot
-============
-
-$ export ATF_LOAD_ADDR=0x80000000
-$ export BL33_LOAD_ADDR=0x80020000
-$ make imx8qm_rom7720_a1_4G_defconfig
-$ make u-boot.bin
-$ make flash.bin
-
-Flash the binary into the SD card
-=================================
-
-Burn the flash.bin binary to SD card offset 32KB:
-
-$ sudo dd if=flash.bin of=/dev/sd[x] bs=1k seek=32 conv=fsync
-
-Boot
