* [edk2-platforms][PATCH 1/1] RPi: allow selecting which system config tables are exposed

From: Andrei Warkentin @ 2020-05-06  0:59 UTC (permalink / raw)
  To: devel; +Cc: ard.biesheuvel, leif, pete, philmd

Today we just have an option to hide DT entirely, while ACPI
is always exposed. This change extends the option to
provide all three choices:
- ACPI only
- ACPI + DT
- DT only

Why? Because not all OSes will prefer DT over ACPI when both are available.

To do this cleanly, move the variable structure and value definitions
into a separate header, ConfigVars.h.
