[Buildroot] [PATCH 1/2] Initial support for I.MX6 SabreAuto board

[Arnout Vandecappelle <arnout@mind.be>]

  Hi Abdul,

  Thank you for your contribution. Even on this very small defconfig I 
have a few comments :-)

  We prefer to use the internal toolchain for minimal defconfigs.

  I do realize that that means you won't be able to use this defconfig as 
a basis for adding the codec and GPU libraries. As a solution, we have 
decided to also accept 'demo' defconfigs in the future that create a more 
extensive configuration that shows more of a board's capabilities.

  Why udev and not the default devtmpfs? udev adds a lot of bloat...

  Minor nit: the /dev/ttymxc count patch should come first in the series.

  Better to download a tarball from

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/snapshot/imx_3.0.35_4.1.0.tar.bz2

That goes about 10 times faster.

  Why a custom git? AFAICS there are no relevant differences between this 
version and the released uboot-2013.10?
