+
+Quick Start
+===========
+
+- Build the ARM Trusted firmware binary
+- Get scfw_tcm.bin and ahab-container.img
+- Build U-Boot
+- 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

+$ ./firmware-imx-8.0.bin
+
+Copy the following binaries to U-Boot folder:
+
+$ cp imx-atf/build/imx8qm/release/bl31.bin .
+$ cp u-boot/u-boot.bin .
+
+Copy the following firmwares U-Boot folder :
+
+$ cp firmware-imx-7.6/firmware/seco/ahab-container.img .
+$ cp imx-sc-firmware-0.7/mx8qm-mek-scfw-tcm.bin	.
+
+Build U-Boot
+============
+$ export ATF_LOAD_ADDR=0x80000000
+$ export BL33_LOAD_ADDR=0x80020000
+$ make imx8qm_mek_defconfig
+$ make flash.bin
