[U-Boot] [PATCH 05/11] mx6sabresd: Add Windows boot support for iMX6 Sabre

Sat Jul 14 00:11:49 UTC 2018

From: Henry Beberman <henry.beberman at microsoft.com>

This patch adds a new bootable configuration for Windows 10 IoT Core on
the i.MX6 Quad Sabre board.

Add a new device tree sources file for imx6qdl-sdb. This is not
required by Windows or UEFI but the build system requires a device
tree when building SPL with flat image tree support.
