+U-Boot for the NXP i.MX8QM ROM 7720a1 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/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
+------------
+
+.. code-block:: bash
+
+ $ 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:
+
+.. code-block:: bash
+
+ $ sudo dd if=flash.bin of=/dev/sd[x] bs=1k seek=32 conv=fsync
+
+Boot
