42 The kernel source tree includes a number of firmware 'blobs'
43 which are used by various drivers. The recommended way to
44 use these is to run "make firmware_install" and to copy the
45 resulting binary files created in usr/lib/firmware directory
46 of the kernel tree to the /lib/firmware on your system so
47 that they can be loaded by userspace helpers on request.
48
49 Enabling this option will build each required firmware blob
50 into the kernel directly, where request_firmware() will find
51 them without having to call out to userspace. This may be
52 useful if your root file system requires a device which uses
53 such firmware, and do not wish to use an initrd.
54
55 This single option controls the inclusion of firmware for
56 every driver which usees request_firmare() and ships its
57 firmware in the kernel source tree, to avoid a proliferation
58 of 'Include firmware for xxx device' options.
59
60 Say 'N' and let firmware be loaded from userspace.
