configs/freescale_imx8mnevk: new defconfig
This patch adds support for the i.MX8M Nano EVK Board [1]. The final boot image is created from uboot and firmware binaries in post image script board/freescale/common/imx/imx8-bootloader-prepare.sh Note that this config is based on 4.19.35_1.1.0 ; hence, the kernel configuration needs host-openssl to build.

+***************************
+Freescale i.MX8MN EVK board
+***************************
+
+This file documents the Buildroot support for the i.MX8M Nano EVK board.
+
+Build
+=====
+
+First, configure Buildroot for the i.MX8MN EVK board:
+
+ make freescale_imx8mnevk_defconfig
+
+Build all components:
+
+ make
+
+You will find in output/images/ the following files:
+ - bl31.bin
+ - boot.vfat
+ - ddr4_201810_fw.bin
+ - ddr_fw.bin
+ - fsl-imx8mn-ddr4-evk.dtb
+ - Image
+ - imx8-boot-sd.bin
+ - rootfs.ext2
+ - rootfs.ext4
+ - rootfs.tar
+ - sdcard.img
+ - u-boot.bin
+ - u-boot.imx
+ - u-boot.itb
+ - u-boot-nodtb.bin
+ - u-boot-spl.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.MX8MN EVK board
+==========================
+
+To boot your newly created system (refer to the i.MX8MNano EVK Quick Start Guide
+[1] for guidance):
+- insert the SD card in the SD slot of the board;
+- Configure the switches as follows (X = "don't care"):
+SW1101: 1100XXXXXX [D1-D10]
+SW1102: XXXXXXXXXX [D1-D10]
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+ emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!
