+***************************
+Freescale i.MX8mq EVK board
+***************************
+
+This file documents the Buildroot support for the Freescale i.MX8mq
+EVK board.
+
+Hardware support
+================
+
+Currently only basic support for hardware is available, currently no
+support for GPU, VPU and other HW features.
+
+Build
+=====
+
+First, configure Buildroot for the i.MX8mq EVK board:
+
+ make freescale_imx8mqevk_defconfig
+
+Build all components:
+
+ make
+
+You will find in output/images/ the following files:
+ - bl31.bin
+ - boot.vfat
+ - fsl-imx8mq-evk.dtb
+ - Image
+ - imx-boot-imx8mqevk-sd.bin
+ - lpddr4_pmu_train_fw.bin
+ - rootfs.ext2
+ - rootfs.ext4
+ - rootfs.tar
+ - sdcard.img
+ - signed_hdmi_imx8m.bin
+ - u-boot.bin
+ - u-boot.imx
+ - u-boot-nodtb.bin
+ - u-boot-spl-ddr.bin
+
+Create a bootable SD card
+=========================
+
+To determine the device associated to the SD card have a look in the
+/proc/partitions file:
+
+ cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a SD card. Launch the following
+command as root:
+
+ dd if=output/images/sdcard.img of=/dev/<your-sd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/common/imx/genimage.cfg.template_imx8.
+
+Boot the i.MX8mq EVK board
+==========================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+ emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enable HDMI output
+==================
+
+To enable HDMI output at boot you must provide the video kernel boot
+argument. To set the video boot argument from U-Boot run after
+stoping in U-Boot prompt:
+
+setenv mmcargs 'setenv bootargs console=${console} root=${mmcroot} video=HDMI-A-1:1920x1080-32@60'
+saveenv
+reset
+
+Change screen resolution to suit your connected display.
+
+Enjoy!
