In linux kernel since version 2.6.27 (release Date: 2008-10-09)
Various drivers in the kernel source tree may require firmware,
which is generally available in your distribution's linux-firmware
package.
The linux-firmware package should install firmware into
/lib/firmware/ on your system, so they can be loaded by userspace
helpers on request.
Enabling this option will build each required firmware blob
specified by EXTRA_FIRMWARE into the kernel directly, where
request_firmware() will find them without having to call out to
userspace. This may be useful if your root file system requires a
device that uses such firmware and you do not wish to use an
initrd.
This single option controls the inclusion of firmware for
every driver that uses request_firmware(), which avoids a
proliferation of 'Include firmware for xxx device' options.
Say 'N' and let firmware be loaded from userspace.
