+NXP i.MX8MN DDR4 EVK
+====================
+
+This is a Buildroot target for building an image for the imx8mn-ddr4-evk
+board using upstream components: TF-A, U-Boot and kernel.
+
+How to build it
+===============
+
+Configure Buildroot and build it:
+
+  $ make imx8mn-ddr4-evk_defconfig
+  $ make
+
+Flashing the SD card image
+==========================
+
+Copy the sdcard.img file into the SD card:
+
+  $ sudo dd if=output/images/sdcard.img of=<your-sd-device>; sync
+
+
+Booting the board
+=================
+
+To boot your newly created system:
+
+- Insert the SD card in the MicroSD slot of the board.
+- Connect a serial to USB cable to the DEBUG port.
+- Open a terminal on ttyUSB2 port. For example: sudo picocom -b 115200 /dev/ttyUSB1
+- Power on the board.
