Issue to track addition of AGL reference hardware support.  For reference, the known requirements are:

• The ref h/w should if at all possible reuse the h3ulcb build with just a different devicetree file.  This avoids any changes to the current build / CI platforms.
• The ref h/w should not require the meta-rcar-gen3-adas layer (aka Kingfisher support).  This avoids conflicts with the substantial kernel changes contained in that layer.
• The firmware and U-Boot builds for the ref h/w are not required to be integrated into the h3ulcb build initially, and potentially ever.  This is driven by the ref h/w requiring incompatible build flags for the firmware.  It should be documented how to build them if someone does end up needing them.
