From: Frieder Schrempf <frieder.schrempf(a)kontron.de>
This adds support for i.MX6UL/ULL-based evaluation kits with SoMs by
Kontron Electronics GmbH.
Currently there are the following SoM flavors (SoM-Line):
* N6310: SOM with i.MX6UL-2, 256MB RAM, 256MB SPI NAND
* N6311: SOM with i.MX6UL-2, 512MB RAM, 512MB SPI NAND
* N6411: SOM with i.MX6ULL, 512MB RAM, 512MB SPI NAND
And the according evaluation boards (Board-Line):
* N6310-S: Baseboard with SOM N6310, eMMC, display (optional), ...
* N6311-S: Baseboard with SOM N6311, eMMC, display (optional), ...
* N6411-S: Baseboard with SOM N6411, eMMC, display (optional), ...
Currently U-Boot describes i.MX6UL and i.MX6ULL through separate config
options at compile-time. Though the differences are so minor, that for
the scope of these SoMs we just use a single defconfig that is compatible
with both SoCs.

Fixes in v3:
* Guard binman nodes to fix build of other UL boards
Fixes in v2:
* Add MAINTAINERS file
* Rename board directory
* Use binman to generate FIT
* Support legacy images
* Add Stefano's R-b tag
