v4:
- remove BR2_ARM_FPU_VFPV3 since this option is not used for aarch64.
The FPU options are set implicit.
v3:
- change offset value to use capitol 'K' value (thanks Guilio)
- add info to uboot patches about submitting to upstream
v2:
- switch to extlinux
- directly call genimage.sh
- remove post-image.sh
- remove BR2_PACKAGE_HOST_UBOOT_TOOLS_BOOT_SCRIPT
- add BR2_LINUX_KERNEL_DTB_KEEP_DIRNAME

+Subject: [PATCH 2/2] imx: imx8mm: imx8mm-kontron-n801x-s: add common board
+ u-boot.dtsi
+
+When using a board variant that selects the lvds specific dtb the
+*.u-boot.dtsi file will not be included. To have a lvds dtb specific
+u-boot.dtsi file move this part to a common board u-boot.dtsi file and
+include this in the board base u-boot.dtsi and create an additional one
+for the lvds variant.

+Kontron BL i.MX8M Mini
+======================
+
+https://www.kontron.com/produkte/baseboard-bl-i.mx8m-mini/p158549
+
+
+How to build it
+===============
+
+Configure buildroot:
+
+ $ make kontron_bl_imx8mm_defconfig
+
+Change settings to fit your needs (optional):
+
+ $ make menuconfig
+
+Compile everything and build the rootfs image:
+
+ $ make
+
+
+Result of the build
+===================
+
+After building, the output/images directory contains:
+
+ output/images/

+
+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
+ * 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
