DynamicTablesPkg: Arm Raw/DSDT/SSDT Generator
A Raw generator is a simple generator. This generator provides
the ability to install a binary blob (that contains ACPI table
data) as an ACPI table. The binary blob could be pre-generated
ACPI table data or it may be the pre-compiled output from an
iAsl compiler for a DSDT or SSDT table.
