ASoC: SOF: ipc4-loader: Support for loading external libraries

Browse source

In case the requested module is not available among the loaded libraries,
try to load it as external library.

The kernel will try to load the file from <fw_lib_prefix>/<module_uuid>.bin

If the file found, then the ext manifest of it is parsed, placed it under
XArray and the pointer to the module is returned to the caller.

Releasing the firmware will be done on ipc cleanup time.
