Since ApolloLake, Intel platforms require signed firmware. On all Windows platforms the default is to require the Intel production key be used. But some platforms allow for a community key to be used, which allows developers to compile/build their own firmware. In the linux-firmware tree, the default intel/sof path is used for firmwares signed for the production key, and files signed with the community key are located in intel/sof/community. Since we don't have an API to query which key is used on what platforms, we have to rely on DMI-based quirks. Developers can bypass this mechanism by setting a kernel 'fw_path' module parameter. Additional dynamic debug traces are provided to help debug cases where the wrong file might be used.
