Some drivers request their firmware very early when built into the
kernel, even before the initramfs is mounted - So the only way to
provide firmware for those drivers is to include them directly in the
kernel with the CONFIG_EXTRA_FIRMWARE option.
To support this, let linux-firmware install its files into
BINARIES_DIR in addition to TARGET_DIR, similar to how we do it for
intel-microcode.
Peter Korsgaard (4):
package/linux-firmware: make target install macros accept a
destination parameter
package/linux-firmware.mk: get rid of temporary tarball for file
installation
package/linux-firmware: also install into images for early loading
support
linux: build after linux-firmware if enabled for early loading support
