The linux-firmware package is definitely installing files to
$(TARGET_DIR):

ifneq ($(LINUX_FIRMWARE_FILES),)
define LINUX_FIRMWARE_INSTALL_FILES
        cd $(@D) && \
                $(TAR) cf install.tar $(sort $(LINUX_FIRMWARE_FILES)) && \
                $(TAR) xf install.tar -C $(TARGET_DIR)/lib/firmware
endef
endif

ifneq ($(LINUX_FIRMWARE_DIRS),)
# We need to rm-rf the destination directory to avoid copying
# into it in itself, should we re-install the package.
define LINUX_FIRMWARE_INSTALL_DIRS
        $(foreach d,$(LINUX_FIRMWARE_DIRS), \
                rm -rf $(TARGET_DIR)/lib/firmware/$(d); \
                mkdir -p $(dir $(TARGET_DIR)/lib/firmware/$(d)); \
                cp -a $(@D)/$(d) $(TARGET_DIR)/lib/firmware/$(d)$(sep))
endef
endif

Could you describe in more details what you are seeing ? Which
configuration are you using ? Could you post the build log of the
linux-firmware package in your situation ?

Best regards,

Thomas
