v4l/Makefile not only calls the kernel Makefile to do the module
building, but it is in turn included by the kernel Makefile. This means
_all_ the rules in v4l/Makefile get used by the kernel Makefile when it
tries to build the modules. Some of these rules, for files like .config,
Kconfig, .version, confuse the kernel building process. The kernel make
thinks, "I need to remake _my_ Kconfig file because my .version file is
out of date." But that rule was never supposed to be used by the kernel,
it is just for v4l!
This is fixed by putting $(obj) in front of all these files' rules. That
way the kernel will never think the rules refer to its files and try to
use them.
Really, this whole business of having the kernel Makefile include
v4l/Makefile is rather complex. It might be a good idea to create
v4l/Kbuild, which the kernel will use in preference to v4l/Makefile, so
that we don't have to worry about v4l/Makefile getting used in two
different contexts.

Create a symlink, v4l/oss, that points back to the v4l directory. This
way code that includes "oss/something.h" will find the header files it
wants (which has been linked to from v4l). The link will be created only
if it doesn't exist and deleted by distclean.

Both .config and Kconfig are created at the same time by the same
program, make_kconfig.pl. make does not understand the concept of
a program which creates two targets and cannot handle this properly.
Everything works with this patch, but in some cases make -j will run
make_kconfig.pl twice at the same time. This works, one script will just
overwrite the output of the other, but it looks bad. Without make -j,
everything works as it should and make_kconfig.pl isn't run more than it
needs to be.

links is a phony target, so it is always remade. The config targets
don't need the source links, so there is no need for them to have links
as a depenedency.

The make_makefile.pl script is re-written. The old one was nasty. This
one will correctly handle Makefile lines that are continued with a
backslash. It will also generate a dependency list of the Makefile used
to create Makefile.media. This way if any change, Makefile.media will be
automatically re-made by make.
The whole business where make_makefile.pl would call make_kconfig.pl is
removed.
The underlying logic of the main Makefile is completely changed. Make
has a feature where it will make sure any included files are up-to-date,
and then restart itself if any were updated. We now take advantage of
this feature.
Detect when make is building only targets which do not need include files
like .myconfig or Makefile.media, and don't include them in those cases.

Add the ability to the make_kconfig.pl script to create a file
named ".kconfig.dep" which can be included in a Makefile and defines the
dependencies of the v4l/Kconfig file. That is, all the individual
Kconfig files that were used to make it.
Added a rule to v4l/Makefile to remake Kconfig when needed, and include
.kconfig.deps to get Kconfig's dependencies. Adjust the config targets
so that they depend on Kconfig, rather than including the commands to
create Kconfig in the config targets' scripts. The config targets no
longer depend on .version, as they don't need it themselves. Rather,
it's Kconfig that needs .version, so it's made one of Kconfig's
dependencies.
Add Kconfig as a dependency to .myconfig, it should be there since the
make_myconfig.pl script uses Kconfig.
Now if you change any of the Kconfig files, the v4l/Kconfig file will
automatically get remade. This will in turn cause .myconfig to be
re-made, and any new options will appear in .myconfig (turned off).
Ideally this should trigger some kind of oldconfig system to update
.config.
Fix the .version rule so that instead of re-creating .version every time,
it is only created when it didn't already exist. Since Kconfig depends
on .version, it was getting re-created every time too. If .version
existed, it would just get re-created to the same thing anyway.
Stop echoing the echo srcdir command itself and don't echo anything if
SRCDIR is blank.

Use a (make 3.81 safe!) in-line perl script to generate config-compat.h
from .myconfig. The output will be more like the Kernel's output:
Options set to 'm' will define CONFIG_WHATEVER_MODULE to 1, rather than
define CONFIG_WHATEVER to m.
Options set to 'y' to be defined to 1 instead of y.
Options that are off will be #undef'ed, rather that omitted, so that they
will override the settings from the kernel autoconf.h file.
The last change will fix a problem where certain options, like CinergyT2
tuning and AV7110 firmware, wouldn't work properly if they were on in the
kernel but off for v4l-dvb Hg.

There were a circular dependency at scripts/make_makefile.pl that were

insmod.sh were a hack, were somebody should check all dependencies
for each module. Several dependencies were mising, and, to keep it
updated for 178 modules is really hard.
rmmod.pl is a "smart" script: it does:
1) Check, for each found module on v4l, the correct order for each
module;
2) Check any dependencies for out-of-tree modules;
3) rmmod/insmod at the correct order;
4) It have a table with the suggested debug parameter for each module.

Since v4l-dvb now uses the kernel's config system, it needs certain kernel
binaries like qconf, mconf, and lxdialog to run the config targets. The
kernel's Makefile is not kind enough to give us a target to just build these
programs. What this patch does is introduce a new makefile,
Makefile.kernel, which includes the kernel's top-level Makefile. Then adds
some new "v4l-*" targets which just build the kernel config programs.
The main v4l Makefile is patched to add the necessary kernel conf programs
as dependencies to their respective config targets. Rules to build the
kernel conf programs are added which invoke a sub-make with the new
Makefile.kernel. These rules are only invoked when the kernel conf programs
needed don't yet exist. If they already exist, no write access to the
kernel source tree is needed.

When building in-kernel, compile-time build options are passed into the
compiler using '#include <linux/config.h>' . This file #include's
<linux/autoconf.h> , which is created on the fly by the kbuild system.
However, this does not work correctly when building from the mercurial
repository, since the kernel is built indepentently of v4l/.myconfig
This creates a "config-compat.h", which will be #include'd by compat.h
and will emulate <linux/config.h> for the local build.

This patch moves the 'make install' and 'make rminstall' rules into the
central Makefile. This allows for us to assign dependencies to these rules,
so that modules built as a reult of a tree-merge don't have to be installed
separately.
Now, instead of doing 'make install && make ivtv-install', the simple
command, 'make install' will call the sub-install rules and take care
of the entire task.

From: Mauro Carvalho Chehab <mchehab@infradead.org>
Previously, tree building were based on Make.config. This file contained all
compiling stuff. Also, v4l/Makefile contained all drivers that should be
copiled, replicating the rules of all other Makefiles under linux.
Now, make will rely on linux/*/Makefile to compile the modules. This approach
allows usage of Kconfig files, allowing partial compilations.
Newer makefile commands introduced:
make allmodconfig - Selects all stuff to be compiled as module;
make config - Selects packages via text interface;
make xconfig - Selects packages via qt interface;
make gconfig - selects packages via gtk interface.
for config, xconfig and gconfig to be used, those scripts needs to be previously
compiled at kernel. So, user needs to use those commands previously at kernel tree.
