db443f263a host-ccache: turn into a proper dependency
This patch moves the host-ccache build target from BASE_TARGETS in Makefile
to an actual host prerequisite in support/dependencies. This causes
host-ccache to be built as part of the dependencies, before any real package
is built.
Since the dependencies are built without ccache anyway, there is no need to
set HOST_CCACHE_CONF_ENV anymore.

f1f97b3a05 system: add option to pass extra args to post-build and post-image scripts
It can be useful to have different configuration use the same post-build
and/or post-image scripts as they share a common infrastructure, but yet
have minor differentiation.

This option allows passing zero or more additional arguments to each
post-build or post-image script.

The same set of extra arguments are passed to all scripts, it is not
possible to pass different arguments to each script.

381616e77a Introduce BR2_TOOLCHAIN_USES_{UCLIBC, GLIBC}
Currently, when we need to do a conditional on the type of C library
used, we need to take into account the three toolchain backends. As we
are going to add eglibc support to the Buildroot toolchain backend, it
would become even uglier, so this patch introduces two new hidden
options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that
exist regardless of the toolchain backend. The entire Buildroot code
base is converted to use those options.

Note that we have intentionally created only one option
(BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are
essentially the same, as far as Buildroot is concerned.

e97376a0fc Makefile: make skeleton rsync options consistent
Initially, a "cp" was used for the one-time target skeleton
installation, and an "rsync" was used for the every-time overlay
skeleton installations.  Then, the target skeleton install was
changed to also use rsync (1cd3f992fb).
Now there are two rsyncs, but with different filter specs, which
seems odd.

This patch adds --excludes to both invocations of rsync to make them
consistent, and removes the -u option from the initial target skeleton
installation.

olddefconfig is a new target available in kconfig that allows to take
an old .config file, and update it to the latest version of the code,
without being asked for questions: it automatically assumes the
default value for options whose value was not defined.

It for example allows to take a minimal defconfig, copy it as .config,
and do 'make olddefconfig' to get the full .config.

13c07c79a4 Makefile: simplify target skeleton copying
We already use the .root stamp file to remember if we have copied the
skeleton, so we can remove the /bin check.

Likewise, we should always have a TARGET_SKELETON (or explicitly error
out otherwise), so remove that check as well.

Finally, now that we're using rsync to do the copy, we might as well
use its exclude support instead of cleaning up unwanted files afterwards.

9fa32ba0b7 Add a post-image script mechanism
Just like we have a post-build script mechanism that gets executed
after the build of all packages but before the creation of the
filesystem images, let's introduce a post-image script mechanism, that
gets executed once all filesystem images have been generated.

This can for example be used to call a tool building a firmware image
from different images generated by Buildroot, or automatically extract
the tarball root filesystem image into some location exported by NFS,
or any other custom action.

1ed4996346 Make savedefconfig save to a configured file.
Store BR2_DEFCONFIG in .config, and use it to update the original input
defconfig file after updating the configuration.  When a config is
created by using the BR2_DEFCONFIG=... option, this is saved in the
.config file; later runs of savedefconfig will update that same location.
It is also possible to configure this place in the interactive
configuration.

The BR2_DEFCONFIG value itself is not saved into the generated
defconfig, since Kconfig considers it at its default. This is
intentional, to avoid hard-coding an absolute path in the defconfig.
It will anyway be set again when the defconfig is used with the
'make BR2_DEFCONFIG=... defconfig' command.

As a side-effect of this change, the *config options have been moved out
of the BR2_HAVE_DOT_CONFIG condition.  This doesn't make any functional
difference, because the .config is still not read for the *config targets.
However, the defconfig and savedefconfig targets do need to include
.config now, which makes them slightly slower.

toolchains available on the system, and then offer those toolchains to
compile Eclipse projects.

In order to interface with this plugin, this commit adds an option
that allows the user to tell whether (s)he wants the Buildroot project
toolchain to be visible under this Eclipse plugin. It simply adds a
line in this ~/.buildroot-eclipse.toolchains file.

2b0f455254 Makefile: export a few variables to help support scripts
Support scripts (in support/) may need to parse the .config file, so give
them an easy access to it, by exporting BUILDROOT_CONFIG with the fully-
qualified path to .config.

Also, post-build scripts may need to reference a few locations, so export
those, too.

Note: we export both O and BASE_DIR. Although they are the same, BASE_DIR
is used internally, while O is used on the command line, which makes it a
bit ambiguous to know which to use. As users use O= on the command line,
they will probably tend to use that in their post-build scripts.

Update doc accordingly.

ebcfa987df pkg-infra: introduce errors for legacy API
As discussed in the BR developer days, we want to be more strict about API
changes in buildroot. I.e., we want to make it less likely that a user's
customizations break down after upgrading buildroot.

A first step is to make sure that the user is warned about API changes.
This patch introduces Makefile.legacy and Config.in.legacy, which will
issue clear error messages for such situations.

9226a9907c Warn the user about the usage of output/target as the root filesystem
A very common mistake done by our users is that they use
output/target/ directory as their root filesystem. Even though this is
loudly documented in our Buildroot manual, people don't read
documentation, so it is not sufficient.

This patch adds a text file named
output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM which explains why
output/target isn't appropriate to use as the root filesystem. The
process is:

 * At the beginning of the build, right after the skeleton has been
   copied, support/misc/target-dir-warning.txt is copied to
   output/target/THIS_IS_NOT_YOUR_ROOT_FILESYSTEM

 * In the filesystem images creation code, this file is removed before
   launching fakeroot, and restored right after that, so that this
   file is not present in the generated root filesystem images.

Note that the file has not been added to the default skeleton for two
reasons:

 * It would have annoying to have in our source tree a file named in
   capital letters inside system/skeleton/

 * The proposed way works even if the user uses a custom skeleton.

6c3e3ad419 New top-level directory: system
This directory groups the following elements:
 * the default root filesystem skeleton
 * the default device tables
 * the Config.in options for system configuration (UART port for
   getty, system hostname, etc.)
 * the make rules to apply the system configuration options

Even though the skeleton and device tables could have lived in fs/, it
would have been strange to have the UART, system hostname and other
related options into fs/. A new system/ directory makes more sense.

As a consequence, this patch also removes target/Makefile.in, which
has become useless in the process.

7e76f904d2 legal-info: infrastructure to collect legally-relevant material
This allows to automatically collect material that may be needed to comply with
the license of packages that Buildroot prepares for the target device.

The core of the implementation is made by the following parts:
 - in package/pkg-utils.mk some helper functions are defined for common actions
   such as generating a warning, producing info about a package etc;
 - in package/pkg-gentargets.mk, within the GENTARGETS framework, a new
   <PKG>-legal-info target produces all the info for a given package;
 - Makefile implements the top-level targets:
   - legal-info-prepare creates the output directory and produces legal info
     about Buildroot itself and the toolchain, which mostly means just warning
     the user that this is not implemented;
   - legal-info, the only target that is supposed to be used directly, depends
     on all of the above and finishes things by producing the README files from
     the various pieces.

07bae75635 source-check: change behavior to check only selected packages / add source-check-all
The original 'source-check' target first selects all packages, and then checks
whether the package tarballs can be found. This is useful for Buildroot
maintainers, but less useful for developers working on a specific project. The
latter only care about the packages used in that project.

This patch removes the allyesconfig dependency to source-check so that only
selected packages are checked. The original behavior is moved to a new target
'source-check-all'.

433290761f ccache: allow dynamic selection of cache directory
The existing ccache infrastructure sets the cache directory hardcoded in the
ccache binary. As this directory was set to ~/.buildroot-ccache, the cache
is not necessarily local (e.g. in corporate environments the home directories
may be mounted over NFS.)
Previous versions of buildroot did allow to set the cache directory, but this
was also hardcoded (so you had to rebuild ccache to change it), plus that
support was removed.
See http://lists.busybox.net/pipermail/buildroot/2011-July/044511.html for
a discussion on this.

This patch modifies ccache to respect a new shell variable (exported from
the Makefile, based on a configuration option) instead of CCACHE_DIR.
The name CCACHE_DIR itself is already used by autotargets for the ccache
package.

aebf199ff0 Add support to generate locale data
In order to use locale support on a Linux system, you need locale data
to be present:

 * on a (e)glibc based system, this data is typically in the
   /usr/lib/locale/locale-archive file, which can be created and
   extended using the localedef program

 * on an uClibc based system, the set of supported locales is defined
   at build time by an uClibc configuration option.

This patch implements generating locale data for the following cases:

 * Internal toolchain

 * External toolchain based on (e)glibc. uClibc external toolchains
   are not supported, because with uClibc, the set of supported
   locales is defined at build time. CodeSourcery and Linaro
   toolchains have been tested, Crosstool-NG toolchains are believed
   to work properly as well.

 * Toolchains built using the Crosstool-NG backend, but only (e)glibc
   toolchains.

This feature was runtime tested with internal uClibc toolchain,
CodeSourcery ARM toolchain and Linaro ARM toolchain, thanks to a
simple C program that shows the data and a gettext translated message.

Note that this option differs from the "purge locales" option, which
is responsible for removing translation files and other locale stuff
installed by packages. At some point in the future, we may want to
clarify the respective roles of those options.

since 16e7b8255c, nfs-utils has been

This patch adds a check for the version of make very early in the Makefile, so
that old make versions are handled gracefully.

4eb982cf90 'source' target should depend on 'dirs'
In the following command flow:
make distclean
make <board>_defconfig
make source

the dl directory would normally be created by the first wget download. If there are no such downloads, e.g. because you use a local download mirror (e.g. scp, file) or only use git/svn/hg/bzr repositories, the dl directory is not created automatically. This causes e.g. the 'pushd' command in the respective _DOWNLOAD commands to fail.

This patch adds a dependency to the 'dirs' target to 'source', fixing this scenario.

Add a simple toolchain wrapper for external toolchains, which forces the
correct sysroot/march/mtune/floating point options needed to use it
with buildroot.

With this in place the external toolchain behaves similar to the internal
ones, and the special handling can be removed. This also means that the
toolchain is usable outside buildroot without having to pass any special
compiler flags.

Also adjust the downloadable external toolchain support to install under
HOST_DIR so it can be used after the temporary build files are removed.

c729829c6c Fix ccache handling
When ccache support is enabled and 'make silentoldconfig' is being
started from the following rule:

$(BUILD_DIR)/buildroot-config/auto.conf: $(CONFIG_DIR)/.config
	$(MAKE) $(EXTRAMAKEARGS) HOSTCC="$(HOSTCC_NOCCACHE)" HOSTCXX="$(HOSTCXX_NOCCACHE)" silentoldconfig

then, the Makefile in package/config inherits from HOSTCC/HOSTCXX
values with the ccache prefix. However, if we start from a cleaned
build (after make clean), ccache is not compiled yet, so things break.

To solve this, we pass a noccache variant of HOSTCC/HOSTCXX down to
the package/config Makefile.

Instead of letting the user define all the details of his external
toolchain, we define a set of profiles for well-known external
toolchains (CodeSourcery ones only at the moment, can easily be
extended with other toolchains).

Once a profile has been choosen, the user is offered the choice of
either letting Buildroot download and install the external toolchain,
or (as before) to tell Buildroot where the toolchain is installed on
the system.

We of course provide a "custom profile", through which the user can
configure Buildroot to use a custom external toolchain for which no
profile is available.

8101c9a357 linux: strip installed modules
The installed kernel modules should have useless build cruft stripped out
of them.  On my system, a default build went from a very unreasonable 30MB
to a normal 3MB (on disk) and from 14MB to 3MB when compressed due to the
info stored in the kernel modules alone.

22c2c6b541 Makefile: handle host packages for make source / make external-deps
Ensure host packages (dependencies of target packages) are also handled
by make source / make external-deps.

This has to be done a explicitly, as we don't list these in Kconfig,
and hence also not in a variable like TARGETS, so instead we have to
look at the <PKG>_DEPENDENCIES variables for each enabled package and
extract the host packages from there.

Host packages can in turn also have dependencies, so we have to follow
those as well. Ideally this should be done recursively, but as that's
pretty hard to do in make, it is limited to 1 level for now.

Finally, host packages share source files with target packages, so
pipe output of make external-deps through sort -u to ensure duplicates
are removed.

5f71fc1f19 Remove support for shared configuration cache
The configuration cache shared between packages, while being in
principle a nice idea to speed-up the configuration of packages by
avoiding repetitive identical checks, turned out to be unreliable due
to the subtle differences between similar but not identical checks in
different packages. After spending some time trying to fix those, we
concluded that supporting the shared configuration cache is definitely
too hard and too unreliable, and that we'd better get rid of it
altogether.

This patch therefore removes the shared configuration cache
infrastructure and usage.

aefad5317f Makefile: generate a Makefile wrapper in $(O)
If building out-of-tree, add a Makefile wrapper that calls-out to the real
Makefile with proper args.

Avoids having to pass -C and O= every time we call make.

This is highly inspired from how the Linux kernel does it, and portions of
it have been used. We can't use exactly the same implementation as the
kernel does, because:

 - the script writing the wrapper has been expunged of the few lines
   that were too kernel-related: in buildroot we do not need the version
   string in the wrapper, and we do not have a patchlevel version;

 - "in-tree build" does not have the same meaning for the kernel and for
   buildroot: for the kernel, $(O) point to the $(TOPDIR), while for
   buildroot $(O) points to $(TOPDIR)/output.

For the latter, the legacy script wget-show-external-deps.sh is no
longer required as $(WGET) isn't called directly anymore but always

0b36880085 Ensure that all config-related files are generated before the build
The previous commit has removed calls to conf_write_autoconf(), which
is the function that generates the KCONFIG_AUTOCONF,
KCONFIG_AUTOHEADER, KCONFIG_TRISTATE files and the split config (with
one file per config item). Therefore, those things were not generated
anymore before the build.

In order to get them generated before the build, we use the same
mechanism as the kernel: run a silentoldconfig when the .config file
is newer than the KCONFIG_AUTOCONF file.

In Buildroot, all those elements are not really used today, except the
split config which is used a little bit in the toolchain build, in a
try to make sure the toolchain gets rebuilt properly when the
configuration changes. It does not seem that this work has been
completed.

However, as we want to keep the same behaviour as previously, we have
to generate all those elements before starting the build.

7c524dd0b6 Clean up our patches against kconfig
Our kconfig-to-buildroot2.patch hasn't been kept up to date with all
the changes made into package/config, and a single patch wasn't very
practical to maintain all our changes. Therefore, this commit adds a
package/config/patches directory, which contains a Quilt series of
patches that correspond to our modifications to the kconfig mechanism.

The huge kconfig-to-buildroot2.patch has been split into 16 smaller
patches. The purpose of some of the modifications has been clearly
identified, while some others were not identified.

The 16 patches together do match exactly the old
kconfig-to-buildroot2.patch. We have been very careful in making sure
that we wouldn't loose any of our modifications.

The only modifications made are :

 * Instead of renaming the kernel Makefile to Makefile.kconfig and
   naming the Buildroot Makefile just 'Makefile', we instead keep the
   original package/config/Makefile from the kernel
   scripts/kconfig/Makefile and name the Buildroot Makefile
   package/config/Makefile.br. The main Buildroot Makefile is modified
   accordingly.

 * The documentation README.buildroot2 is updated to explain how to
   upgrade to a newer version of scripts/kconfig.

 * The kconfig-language.txt documentation is removed, as anybody can
   easily find it in the kernel sources so there's no need to
   duplicate it here.
