The last firmware change for the in-kernel firmware source code was back
in 2013. Everyone has been relying on the out-of-tree linux-firmware
package for a long long time.
So let's drop it, it's baggage we don't need to keep dragging around
(and having to fix random kbuild issues over time...)

This commit actually has no impact because $(src) and $(obj) point
to the same path, but $(src)/Makefile looks better when we include
source files.

The "MAKEFLAGS += --include-dir=$(srctree)" line in the top Makefile
allows us to do this.

Kconfig never defines CONFIG_* as 'n'.
Now obj-n is only used in firmware/Makefile and it can be
replaced with obj-. No makefile uses lib-n.
Let's rip off obj-n and lib-n.

When building the firmware blobs, use a simple loop to create
directories in $(objtree), like in Makefile.build. This simplifies the
rules and also makes it possible to set $(objtree) to '.' later. Before
this change, a dependency on $(objtree)/<dir> would be satisfied by
<dir> in $(srctree).
When installing the firmware blobs, call mkdir like in Makefile.modinst.

Commit fe04ddf7c291 ("kbuild: Do not package /boot and /lib in make
tar-pkg") accidentally reverted two previous kbuild commits. I don't
know what I was thinking.
This brings back changes made by commits 24cc7fb69a5b ("x86/kbuild:
archscripts depends on scripts_basic") and c1c1a59e37da ("firmware: fix
directory creation rule matching with make 3.80")

There were reports of users destroying their Fedora installs by a kernel
tarball that replaces the /lib -> /usr/lib symlink. Let's remove the
toplevel directories from the tarball to prevent this from happening.

Since make 3.80 doesn't support secondary expansion it uses a fallback
rule to create firmware directories which is matched after primary
expansion of the $(installed-fw) rule's prerequisite. Commit
6c7080a61fc7 [firmware: fix directory creation rule matching with make
3.82] changed the expression generated after primary expansion such
that the fallback was not matched. Updating the fallback rule to match
the new look primary expansion is not an option for various reasons.
The trailing slash added here to $(INSTALL_FW_PATH)/. while defining
installed-fw-dirs fixes builds with make 3.82 since this will provide
a matching rule for $(INSTALL_FW_PATH)/$$(dir %) when % is in the base
firmware directory (ie. $(dir %) gives './'). Versions of make prior
to 3.82 will strip this trailing slash along with the one generated by
$(dir %) when % is in the base firmware directory and as such continue
to function as before.

Attempting to run 'firmware_install' with CONFIG_USB_SERIAL_TI=y when
using make 3.82 results in an error
make[2]: *** No rule to make target `/lib/firmware/./', needed by
`/lib/firmware/ti_3410.fw'. Stop.
It turns out make 3.82 is picky when matching directory names with
trailing slashes as a result, where make 3.81 would handle this
correctly make 3.82 does not find the rule needed to create the
directory.
The './' seen in the error is added by $(dir) for firmware which
resides in the base firmware src directory, such as
ti_3410.fw.ihex. By performing $(dir) after we prepend the
$(INSTALL_FW_PATH) we can ensure we don't end up with a './' in the
middle of the path and the directory will be properly created.
This change works with make 3.81 and should work with previous
versions as well.

People don't like them and think they're errors.
Leave the __fw_install one though; when 'make firmware_install' does
nothing, it's best to have a 'Nothing to be done for...' message rather
than just doing nothing.

This means that we no longer need write access to the source tree while
doing 'make modules_install'.

Not the straight conversion to binary which objcopy can do for us, but
actually representing each record with its original {addr, length},
because some drivers need that information preserved.
Fix up 'firmware_install' to be able to build $(hostprogs-y) too.

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.
