+U-Boot for the Congatec conga-QMX8 board
+========================================
+
+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
+--------------------------------------
+
+.. code-block:: bash
+
+     $ 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
+---------------------------------------
+
+.. code-block:: bash
+
+     $ 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:
+
+.. code-block:: bash
+
+     $ 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/mx8qx-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
+------------
+
+.. code-block:: bash
+
+     $ export ATF_LOAD_ADDR=0x80000000
+     $ export BL33_LOAD_ADDR=0x80020000
+     $ make cgtqmx8_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:
+
+.. code-block:: bash
+
+     $ sudo dd if=flash.bin of=/dev/sd[x] bs=1k seek=32 conv=fsync
