From 25bbc0c59ee15cfc37acaaa831de447f2c2fbcb9 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 20 Oct 2022 15:12:30 +0300 Subject: ASoC: SOF: Add path definition for external firmware libraries IPC4 based firmware supports dynamically loaded external libraries. The libraries will be not stored alongside of the firmware or tplg files. For intel platforms the default path will be: intel/avs-lib|sof-ipc4-lib// if a community key is used on the given machine then the libraries will be under 'community' directory, like it is done for the firmware itself.
