The variable 'KERNEL_ARCH' is actually a normalized version of
'ARCH'/'BR2_ARCH'. For example, 'arcle' and 'arceb' both become 'arc', just
as all powerpc variants become 'powerpc'.
It is presumably called 'KERNEL_ARCH' because the Linux kernel is typically
the first place where support for a new architecture is added, and thus is
the entity that defines the normalized name.
However, the term 'KERNEL_ARCH' can also be interpreted as 'the architecture
used by the kernel', which need not be exactly the same as 'the normalized
name for a certain arch'. In particular, for cases where a 64-bit
architecture is running a 64-bit kernel but 32-bit userspace. Examples
include:
* aarch64 architecture, with aarch64 kernel and 32-bit (ARM) userspace
* x86_64 architecture, with x86_64 kernel and 32-bit (i386) userspace
In such cases, the 'architecture used by the kernel' needs to refer to the
64-bit name (aarch64, x86_64), whereas all userspace applications need to
refer the, potentially normalized, 32-bit name.
This means that there need to be two different variables:
KERNEL_ARCH: the architecture used by the kernel
NORMALIZED_ARCH: the normalized name for the current userspace architecture
At this moment, both will actually have the same content. But a subsequent
patch will add basic support for situations described above, in which
KERNEL_ARCH may become overwritten to the 64-bit architecture, while
NORMALIZED_ARCH needs to remain the same (32-bit) case.
This commit replaces use of KERNEL_ARCH where actually the userspace arch is
needed. Places that use KERNEL_ARCH in combination with building of kernel
modules are not touched.
There may be cases where a package builds both a kernel module as userspace,
in which case it may need to know about both KERNEL_ARCH and
NORMALIZED_ARCH, for the case where they differ. But this is to be fixed on
a per-need basis.

As Thomas put it:
The <pkg>_HELP_CMDS variable allows packages using the
kconfig-package infrastructure to display their specific
targets related to the handling of their configuration.
However, it was not consistently used and handled by the
different packages.
So, this commit switches all the kconfig-based package to use the
generic help helper.
As a consequence:
- all kconfig packages now advetise their kconfig-related actions,
where some were previously missing: at91bootstrap3, linux-backports,
swupdate, xvisor;
- busybox advertises it does not support defconfig files;
- the 'foo-savedfconfig' action is no longer advertised: it is to be
considered an internal implementation detail.

Commit 5b95a5dc2 (support/download: change format of archives generated
from git) changed the way the archives generated from git repositories
are named, adding a "format-version" identifier right between the
package version and the file extension.
Commit c043ecb20 (support/download: change format of archives generated
from svn) did so for archives generated from a subversion checkout.
However, for a few packages, we manually force the _SOURCE variable,
because we want to share the archive with another package, to avoid
downloading and storing those archives twice. This is the case for:
- linux-headers and linux
- barebox-aux and barebox
When the generated tarballs were renamed with the aforementioned
commits, those packages were not updated accordingly.
Fix that by manually propagating the per-site-method format-version.

In barebox v2020.09.0, kconfig has been updated to a newer version
based on Linux 5.9-rc2. As in linux, kconfig can call the compiler
to test its capabilities.
We have no way to know if a custom version would require it or not,
so we just unconditionally depend on the toolchain

The buildroot custom bareboxenv compile command misses the additional
include path 'scripts/include' to gain access to the local copy of the
kernel header files (which leads to compile error when using an older
toolchain).
This could be fixed by enhancing the custom bareboxenv compile command
(see [1]) or by using the barebox build system by simply enabling the
CONFIG_BAREBOXENV_TARGET option (available since April 2012, see [2])
instead (as suggested by Yann E. MORIN).
Fixes (with BR2_TARGET_BAREBOX_BAREBOXENV enabled):
build/barebox-2019.12.0/scripts/bareboxenv.c💯10: fatal error: linux/list.h: No such file or directory

[2] https://git.pengutronix.de/cgit/barebox/commit/?id=afb03d7a554a2911a3742e316f011319fcb416f1
Note: a user who would previously provide a barebox config file which
had CONFIG_BAREBOXENV_TARGET=y, but a Buildroot config file which did
not have BR2_TARGET_BAREBOX_BAREBOXENV=y, would have bareboxenv-target
built, but it would not be installed in the target. Now, and unset
BR2_TARGET_BAREBOX_BAREBOXENV will not even build it, but his is not a
regression: it was anyway previously not installed.

When barebox, and thus barebox-aux, are downloaded from a git tree, then
barebox-aux download fails because a hash check is attempted on the
downloaded archive:
Could not fetch special ref 'v2020.03.0'; assuming it is not special.
ERROR: No hash found for barebox-aux-v2020.03.0.tar.gz
This is because we only exclude from the check the archive of the bare
barebox:
BR_NO_CHECK_HASH_FOR += $(BAREBOX_SOURCE)
However, the default name of an archive is based on the package name,
which for barebox-aux is not 'barebox'.
Since barebox-aux really uses the exact same source as the bare barebox,
it should also share the archive name.
This has two direct consequences and advantages:
- the hash check is completely avoided for the barebox-aux archive;
- the barebox-aux archive is not downloaded as it is already
downloaded for barebox.

We can only know the details of the license files for known versions. For
custom, older or newer versions, the license files may change, or may be
moved around.
So, do for Barebox as was done for ATF, linux, and linux-headers, and
only define the list of license files for the latest version.
Add the hash for that license file, and align hashes to the new spacing
convention.

Instead of excluding the hash specifically for the custom tarball and
custom version cases, exclude it always except in the one case where
we do have a hash: the latest version.
This simplifies the code a little because soon we will add hash checks
for git as well, so we also need an exclusion in that case.
It is not needed to exclude it twice for barebox and barebox-aux,
because they use the same source tarball and barebox-aux can only be
enabled if barebox is enabled. So simplify even further by pulling
the exclusion logic out of inner-barebox-package.

This unique NAME is used to construct a per br2-external tree variable,
BR2_EXTERNAL_$(NAME)_PATH, which contains the path to the br2-external
tree.
This variable is available both from Kconfig (set in the Kconfig
snippet) and from the .mk files.
Also, display the NAME and its path as a comment in the menuconfig.
This will ultimately allow us to support multiple br2-external trees at
once, with that NAME (and thus BR2_EXTERNAL_$(NAME)) uniquely defining
which br2-external tree is being used.
The obvious outcome is that BR2_EXTERNAL should now no longer be used to
refer to the files in the br2-external tree; that location is now known
from the BR2_EXTERNAL_$(NAME)_PATH variable instead. This means we no
longer need to expose, and must stop from from exposing BR2_EXTERNAL as
a Kconfig variable.
Finally, this also fixes a latent bug in the pkg-generic infra, where we
would so far always refer to BR2_EXTERNAL (even if not set) to filter
the names of packages (to decide whether they are a bootloader, a
toolchain or a simple package).
Note: since the variables in the Makefile and in Kconfig are named the
same, the one we computed early on in the Makefile will be overridden by
the one in .config when we have it. Thus, even though they are set to
the same raw value, the one from .config is quoted and, being included
later in the Makefile, will take precedence, so we just re-include the
generated Makefile fragment a third time before includeing the
br2-external's Makefiles. That's unfortunate, but there is no easy way
around that as we do want the two variables to be named the same in
Makefile and Kconfig (and we can't ask the user to un-quote that variable
himself either), hence this little dirty triple-inclusion trick.
