+Freescale i.MX6ULL EVK board
+****************************
+
+This file documents the Buildroot support for the Freescale i.MX6ULL EVK board.
+
+Build
+=====
+
+First, configure Buildroot for your i.MX6ULL EVK board:
+
+In order to to do so there are two supported options:
+
+  make freescale_imx6ullevk_defconfig
+
+if you plan to use NXP provided U-Boot and kernel.
+
+or
+
+  make imx6ullevk_defconfig
+
+if you plan to use mainline U-Boot and mainline kernel.
+
+Build all components:
+
+  make
+
+You will find in output/images/ the following files:
+  - boot.vfat
+  - imx6ull-14x14-evk.dtb
+  - rootfs.ext2
+  - rootfs.ext4
+  - rootfs.tar
+  - sdcard.img
+  - u-boot.bin
+  - u-boot.imx
+  - zImage
+
+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.
+
+Boot the i.MX6ULL EVK board
+===========================
+
+To boot your newly created system (refer to the i.MX 6ULL EVK Quick Start Guide [1] for guidance):
+- insert the SD card in the micro 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.
+
+Enjoy!
