[Buildroot] [RFC PATCH] configs: Add support for Toradex Colibri Vybrid modules

[Sanchayan Maity]

This is a minimal default configuration for Colibri Vybrid modules
tested on Colibri Vybrid VF50 and VF61.

Vybrid is well supported in mainline kernel by Toradex however we
use the custom git branches maintained by Toradex. The configuration
only builds a minimal root filesystem and u-boot plus flash scripts
support is not added at the moment.

+Build instructions
+------------------
+
+As a regular user configure and then build:
+
+$ make colibri_vf_defconfig
+$ make
+
+This configuration will use a linux kernel from the git trees
+maintained by Toradex and build a minimal root file system.
+
+Flashing the board
+------------------
+
+Details can be found at:
+http://developer.toradex.com/knowledge-base/flashing-linux-on-vybrid-modules
+
+The above configuration would result in building of rootfs.ubifs image. After
+preparing the SD card as per the instructions on the above article, replace the
+ubifs.img file in the SD card with rootfs.ubifs image file, renaming it to
+ubifs.img and follow the updation procedure on the above article.
