5e26da4673 docs/manual: rephrase paragraph about unsupported external toolchains
The ELDK now relies on Yocto, so it no longer has the funky
non-standard way of doing multilib. Also, we didn't mention that Yocto
toolchains/SDK are not suitable for usage with Buildroot. Therefore,
this commit rewords this part of the documentation to explain that
Yocto/OpenEmbedded SDKs cannot be used as external toolchains in
Buildroot, and why.

ba4146c37c docs/manual: update informations about C library in internal backend
Now that we have eglibc and glibc support in the internal backend, and
no longer marked as experimental, a little bit of rewording is
needed. It is no longer necessary to indicate that uClibc was
historically supported as the only C library, and that the glibc
support is experimental. We also update the rest of the description to
be less uClibc specific.

There is no need to tell people that they should remove stamp files: they

a524731012 manual: add explanations on limitations about using O=...
Using a relative path for O=... has limitations, since it is interpreted
relative to the Buildroot tree, and thus may lead to unexpected results.

For example, running this:
    make -C buildroot O=my-O

will not create my-O in the current working directory, but as a
sub-directory of the Buildroot tree, here in buildroot/my-O

Explain this in the manual (as is similarly done for BR2_EXTERNAL).
Also add a note that $(O) will be created if missing.

Also change O=.. and -C .. to O=<...> and -C <...> to make it explicit
this is an ellipse, not a relative path.

1de64ec8c0 manual: switch BR2_EXTERNAL examples to use absolute paths
Although it is possible to use relative paths, there are a few pitfalls
when doing so.

To avoid confusion for a (newcoming) user, use absolute paths in the
manual (as is done in examples for $(O)), since it is guaranteed to be
working without corner cases.

Developpers Day in Pragues, 2011-10-28:
    http://lists.busybox.net/pipermail/buildroot/2011-November/047229.html

We consider the opinions expressed in that report to be still valid
now, two years later.

This patch converts udev to a virtual package. For the moment, there is only

Packages meant to provide udev-like features must select the symbol
BR2_PACKAGE_HAS_UDEV.

Packages depending on BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_UDEV or
BR2_PACKAGE_UDEV have been converted to use the new symbol.

This is confusing, especially for long-checked-out repositories where
the top-level manual.txt has not changed since the check out. Moreover,
the manual explicitly states 'generated on', which is confusing at best.

Use the current date and time instead.

f4ea4b9824 Config.in: Add a menu around BR2_EXTERNAL configuration options
To make it clear to the user that these options are external to Buildroot
and no support is provided by the Buildroot community.

With this, there's no need to recommend people to their options inside
a menu, so remove that from the documentation.

Kconfig nicely allows us to hide the menu completely if BR2_EXTERNAL isn't
used, so make use of that to not confuse people. It would be nice if we
could add some help text to explain the BR2_EXTERNAL stuff as well, but
that isn't supported on menus :/

a4239f7fd1 core: introduce the BR2_EXTERNAL variable
This commit introduces the BR2_EXTERNAL environment variable, which
will allow to keep Buildroot customization (board-specific
configuration files or root filesystem overlays, package Config.in and
makefiles, as well as defconfigs) outside of the Buildroot tree.

This commit only introduces the variable itself, and ensures that it
is available within Config.in options. This allows us to use
$BR2_EXTERNAL in a 'source' statement in Config.in.

Following patches extend the usage of BR2_EXTERNAL to other areas
(packages and defconfigs).

In details, this commit:

 * Introduces the BR2_EXTERNAL Kconfig option. This option has no
   prompt, and is therefore not visible to the user and also not
   stored in the .config file. It is automatically set to the value of
   the BR2_EXTERNAL environment variable. The only purpose of this
   BR2_EXTERNAL Kconfig option is to allow $BR2_EXTERNAL to be
   properly expanded when used inside Kconfig source statements.

 * Calculates the BR2_EXTERNAL value to use. If passed on the command
   line, then this value is taken in priority, and saved to a
   .br-external hidden file in the output directory. If not passed on
   the command line, then we read the .br-external file from the
   output directory. This allows the user to not pass the BR2_EXTERNAL
   value at each make invocation. If no BR2_EXTERNAL value is passed,
   we define it to support/dummy-external, so that the kconfig code
   finds an existing $(BR2_EXTERNAL)/package/Config.in file to
   include.

 * Passes the BR2_EXTERNAL into the *config environment, so that its
   value is found when parsing/evaluating Config.in files and .config
   values.

f678e31086 manual: do not generate .pyc files
Python saves a pre-compiled support/scripts/kconfiglib.pyc file
side-to-side with the corresponding .py file.

This does not work if the Buildroot source tree is read-only (but
this is not an error for Python, which keep going OK).

But this may cause issues for out-of-tree builds in case the same
Buildroot source tree is shared by many builds.

Also, 'make clean' currently does not clean this file, and out-of-tree
builds can remove it either, at the risk of causing issues for other
out-of-tree builds running at the same time.

Just tell Python not to generate .pyc files:
  - call the script via python, don't use the sha-bang
  - thus, make the script non-executable, and remove the sha-bang

09dea8e8fb docs/manual: limit the depth of the TOC in the HTML output
The current TOC level is set to 4, which does not mean 'a 4-level deep TOC',
but really means 'a TOC deep to the 4th level', with the first level being
level 0, which means we have:

    12. Appendix
        12.1. Makedev syntax documentation
        12.2. Makeuser syntax documentation
        12.3. Partition table layout description syntax
            12.3.1. The global section
                Properties for the global section

Which a bit too much. And yet, the fifth level is not shown, since we
don't have any! :-/

Limit the depth of the TOC to three levels, which is just enough to be
usefull, yet not cluttered by low-level titles.

2c13d5bc60 package: add a <pkg>_EXTRA_DOWNLOADS variable
Converting the external toolchain logic into a package raises a very
special use case that wasn't handled by the package infrastructure:
the Blackfin toolchain is delivered as two tarballs instead of
one. Unfortunately <pkg>_SOURCE only allows to pass one tarball name.

However, we really want both tarballs to be known by the package
infrastructure, so that the normal 'source' and 'external-deps'
mechanism work fine.

In order to achieve this, we add a <pkg>_EXTRA_DOWNLOADS variable,
which allows a package to list other stuff it would like to see
downloaded, but that are otherwise not used by the package
infrastructure itself: it is up to the package to do it by itself.
