Given the large overlap of SoCs that support both SystemReady IR and
SystemReady ES, I asked Simon how hard it would be to pass ACPI tables,
instead of DTB.  Are there going to be some challenges to be able to get
ES certified under U-Boot?  Certainly.  But I'm not convinced that
U-Boot is just a wrong-fit for the ES case when part of the whole point
of these certifications is that it doesn't matter what's implementing
it, it's a standard.
