+U-Boot for the TQ-Systems TQMa7x modules
+########################################
+
+This file contains information for the port of
+U-Boot to the TQ-Systems TQMa7x modules.
+
+***********
+Boot source
+***********
+
+The following boot sources are supported:
+
+- SD/eMMC
+- USB (SDP)
+
+QSPI boot is functional but requires an additional prepended NXP header
+image. This currently unsupported in u-boot.
+
+********
+Building
+********
+
+To build U-Boot for the TQ-Systems TQMa7x modules:
+
+.. code-block:: bash
+
+       make tqma7_mba7_<boot>_defconfig
+       make
+
+**boot** is a placeholder for the boot device:
+
++------+-----------+
+| mmc  | SD/eMMC   |
++------+-----------+
+| uuu  | USB (SDP) |
++------+-----------+
+
+The default build artifact is named ``u-boot-with-spl.imx``.
+
+*****************************************
+Serial Download Protocol (SDP) / USB boot
+*****************************************
+
+The complete system image can be programmed with ``uuu``
+(https://github.com/nxp-imx/mfgtools) to eMMC.
+
+Serial Download Protocol is supported on the Micro-B USB port (X5) of MBa7x.
+The command ``fastboot usb 0`` is used to enable the fastboot gadget.
+
+Build SDP enabled U-Boot image
+==============================
+
+.. code-block:: bash
+
+       make <som>_mba7_uuu_defconfig
+       make
+
+Booting
+=======
+
+With UUU
+
+.. code-block:: bash
+
+       uuu -b spl <UUU U-Boot image>
