+Kontron pitx-imx8m
+==================
+
+https://www.kontron.com/produkte/pitx-imx8m/p155258
+
+
+How to build it
+===============
+
+Configure buildroot:
+
+  $ make kontron_pitx_imx8m_defconfig
+
+Change settings to fit your needs (optional):
+
+  $ make menuconfig
+
+Compile everything and buildr the rootfs image:
+
+  $ make
+
+
+Result of the build
+===================
+
+After building, the output/images directory contains:
+
+  output/images/
+    ├── bl31.bin
+    ├── boot.scr
+    ├── ddr_fw.bin
+    ├── Image
+    ├── imx8-boot-sd.bin
+    ├── imx8mq-kontron-pitx-imx8m.dtb
+    ├── lpddr4_pmu_train_fw.bin
+    ├── rootfs.ext2
+    ├── rootfs.ext4 -> rootfs.ext2
+    ├── rootfs.tar
+    ├── sdcard.img
+    ├── signed_hdmi_imx8m.bin
+    ├── u-boot.bin
+    ├── u-boot.itb
+    ├── u-boot-nodtb.bin
+    ├── u-boot-spl.bin
+    └── u-boot-spl-ddr.bin
+
+
+Flashing the SD card image
+==========================
+
+To install the image on a SDCard simply copy sdcard.img to the storage (e.g. SD, eMMC)
+
+  $ sudo dd if=output/images/sdcard.img of=<your-sd-device>
+
+
+Preparing the board
+===================
+
+ * Connect a serial line to the board
+ * Insert the SD card
+ * Make sure the boot source selection DIP switches are set correctly
+  * SW1 1-4 OFF
+  * SW1 2-3 OFF
+ * Power-up the board
+
+
+Booting the board
+=================
+
+By default the bootloader will search for the first valid image, starting
+with the internal eMMC. To make sure the bootloader loads bootscript from
+the correct location (SD card) set the boot_targets environment variable:
+
+  $ setenv boot_targets mmc1
