As a follow up to the changes proposed by Laszlo to make ACPI and DT
mutually exclusive on ArmVirtQemu, this patch proposes a DT platform
DXE driver that either installs the NULL protocol PlatformHasAcpiGuid,
or installs the FV embedded DTB binary as a configuration table under
the appropriate GUID, depending on a preference setting recorded as
a UEFI variable, and configurable via a HII screen.
The DTB binary can be embedded in the firmware image by adding the
following to the platform .fdf file:
FILE FREEFORM = 25462CDA-221F-47DF-AC1D-259CFAA4E326 {
SECTION RAW = SomePkg/path/to/foo.dtb
}
