+U-Boot for the Toradex Apalis iMX8QM V1.0B Module
+
+Quick Start
+===========
+
+- Build the ARM trusted firmware binary
+- Get scfw_tcm.bin and ahab-container.img
+- Build U-Boot
+- Load U-Boot binary using uuu
+- Flash U-Boot binary into the eMMC
+- Boot
+
+Get and Build the ARM Trusted Firmware
+======================================
+
+$ git clone -b imx_4.14.78_1.0.0_ga https://source.codeaurora.org/external/imx/imx-atf
+$ cd imx-atf/
+$ make PLAT=imx8qm bl31
+
+Get scfw_tcm.bin and ahab-container.img
+=======================================
+
+$ wget https://github.com/toradex/meta-fsl-bsp-release/blob/toradex-sumo-4.14.78-1.0.0_ga-bringup/imx/meta-bsp/recipes-bsp/imx-sc-firmware/files/mx8qm-apalis-scfw-tcm.bin?raw=true
+$ mv mx8qm-apalis-scfw-tcm.bin\?raw\=true mx8qm-apalis-scfw-tcm.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
+
+Copy the following binaries to the U-Boot folder:
+
+$ cp imx-atf/build/imx8qm/release/bl31.bin .
+$ cp u-boot/u-boot.bin .
+
+Copy the following firmware to the U-Boot folder:
+
+$ cp firmware-imx-8.0/firmware/seco/ahab-container.img .
+
+Build U-Boot
+============
+
+$ make apalis-imx8qm_defconfig
+$ make u-boot-dtb.imx
+
+Load the U-Boot Binary Using UUU
+================================
+
+Get the latest version of the universal update utility (uuu) aka mfgtools 3.0:
+
+https://community.nxp.com/external-link.jspa?url=https%3A%2F%2Fgithub.com%2FNXPmicro%2Fmfgtools%2Freleases
+
+Put the module into USB recovery aka serial downloader mode, connect USB device
+to your host and execute uuu:
+
+sudo ./uuu u-boot/u-boot-dtb.imx
+
+Flash the U-Boot Binary into the eMMC
+=====================================
+
+Burn the u-boot-dtb.imx binary to the primary eMMC hardware boot area partition:
+
+load mmc 1:1 $loadaddr u-boot-dtb.imx
+setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
+mmc dev 0 1
+mmc write ${loadaddr} 0x0 ${blkcnt}
+
+Boot
