This patch set provides support for different XEA board revisions. Due to very limited SPL size, the board's switch DTB decision is performed very early in u-boot proper; before driver model is set.
Adjustments for DTS between revisions are for the u-boot adjustment code (i.e. tweaks due to functionality not supported in u-boot), hence there is no need to update them from Linux upstream DTS.
