This patch contains a script which automatically download and compile all
needed tools to build a simple MTD images for booting Maemo kernel image by
U-Boot from RAM, eMMC and OneNAND. MTD images are then run in virtual n900
machine provided by qemu-linaro project.

It can be used to check that U-Boot for Nokia N900 is not broken and can be
successfully booted in emulator.

Script is registered in to .travis.yml so it would be automatically run on
Travi CI service.
