These header files presumably duplicate things already in the U-Boot
devicetree. For now, bring them in to get the ASL code and ACPI table
code to compile.

Hi Tom,
can you please clarify or point us to some documentation that explains
the new DT setup?
I thought the u-boot DT is only used for u-boot internal drivers.
Do we need to upstream the kernel DT first?
Do we need to provide a complete "kernel DT" to u-boot as well?
Regards,
Patri
