Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

/*
|
|
* Loadable firmware support.
|
|
*
|
|
* The firmware abstraction provides an interface for loading firmware
|
|
* images into the kernel and making them available to clients.
|
|
*
|
|
* Firmware images are usually embedded in kernel loadable modules that can
|
|
* be loaded on-demand or pre-loaded as desired. Modules may contain
|
|
* one or more firmware images that are stored as opaque data arrays
|
|
* and registered with a unique string name. Clients request
|
|
* firmware by name, and are returned a struct firmware * below on success.
|
|
* The kernel keeps track of references to firmware images to allow/prevent
|
|
* module/data unload.
|
|
*
|
|
* When multiple images are stored in one module, the first image is
|
|
* treated as the master with the other images holding references
|
|
* to it. This means that to unload the module each dependent/subimage
|
|
* must first have its references removed.
|
|
* In order for automatic loading to work, the master image must have
|
|
* the same name as the module it is embedded into.
