ACPICA: iASL table disassembler: Added disassembly support for the NHLT ACPI table
ACPICA commit 94abe858583de24a425b37cb8e62d56c65c4f3cf Note: support for Vendor-defined microphone arrays and SNR extensions are not supported at this time -- mostly due to a lack of example tables. Actual compiler support for NHLT is forthcoming. Link: https://github.com/acpica/acpica/commit/94abe858 Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Rafael J.
