This patch adds a new bootable configuration for Windows 10 IoT Core on the i.MX7 Dual Sabre board.
It enables SPL on the i.MX7 Sabre in order to support the FIT load of OP-TEE and U-Boot proper.

It doesn't look like this patch is specific to mx7 or Windows. Perhaps it should be in a different commit?
Also, the help text for SPL_DM says it turns on basic DM support in SPL. But not any specific hardware drivers. Those all have additional config options to turn them on. It doesn't seems right to bundle a selection of GPIO drivers along with CONFIG_SPL_DM.
