Removal of unlicensed Linux kernel firmware
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By default, the ``linux-firmware`` recipe now excludes firmware that do not
provide any license information. The recipe holds an internal list of firmware
to exclude via a variable named ``REMOVE_UNLICENSED``, this variable may be
overridden if unlicensed firmware is needed. See :oe_git:`the recipe

overview of the removed firmware.
