+Toradex Colibri i.MX6 Computer on Module
+
+Intro
+=====
+
+The Colibri iMX6 is a SODIMM sized computer module based on NXP®/Freescale
+i.MX 6 SoC. The module targets a wide range of applications, including:
+Medical Devices, Navigation, Industrial Automation, HMIs, Avionics,
+Entertainment system, POS, Data Acquisition, Thin Clients, Robotics, Gaming
+and much more. It offers a wide range of interfaces from simple GPIOs, industry
+standard I2C, SPI, CAN, and UART buses through to high speed USB 2.0 interfaces
+and a 16/32bit external memory bus (parallel bus). The HDMI interface makes it
+very easy to connect large, full HD resolution displays
+
+https://www.toradex.com/computer-on-modules/colibri-arm-family/nxp-freescale-imx6
+
+It supports one carrier boards:
+
+Colibri Evaluation Board
+https://www.toradex.com/products/carrier-board/colibri-evaluation-board
+
+How to build it
+===============
+
+Configure Buildroot:
+
+ $ make toradex_colibri_imx6_defconfig
+
+Compile everything and build the rootfs image:
+
+ $ make
+
+How to boot the image
+=====================
+
+The board only boots from its internal flash memory eMMC, so the
+bootloader image should be copied to it, following the procedures
+described in Toradex website.
+
+http://developer.toradex.com/knowledge-base/flashing-linux-on-imx6-modules
+
+Buildroot prepares a "sdcard.img" in output/images/ with the kernel
+image, device tree and a root filesystem, ready to be dumped on an SD
+card.
+
+ $ dd if=output/images/sdcard.img of=/dev/sdX bs=1M
+
+To boot from the SD card, you should change the U-Boot
+environment. Since U-Boot is running from internal eMMC, you will need
+to access its command line prompt and manually set the necessary
+variables to boot from the external SD card. For convenience, you can
+use uEnv.txt provided in output/images/ as a reference to create the
+necessary U-Boot variables to boot from the SD card.
