From 88ecf814c47f577248751ddbe9626d98aeef5783 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Thu, 29 May 2008 11:01:51 +0300 Subject: firmware: Add firmware installation to modules_install, add firmware_install For 'make modules_install', install any firmware required by the modules which are being installed. Also add a 'make firmware_install' target which doesn't depend on the configuration, but installs _all_ available in-kernel-tree firmware into $(INSTALL_FW_PATH), which defaults to /lib/firmware. This is intended for distributors to make arch-independent (and config-independent) packages containing firmware.

Fix up 'firmware_install' to be able to build $(hostprogs-y) too.
