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.

If U-Boot CONFIG_OF_SEPARATE is defined [1], then the device tree will
be built and placed in a u-boot.dtb file alongside u-boot.bin.
When BR2_TARGET_UBOOT_FORMAT_DTB is enabled, buildroot will copy
u-boot.dtb to $(BINARIES_DIR).
This is useful for RISC-V platforms that want to build OpenSBI with an
external DTB by using FW_FDT_PATH [2].

Commit 2eaa6d0f36 (boot/uboot: fix uboot building host tools on x86
architecture) added use of $(PKG_CONFIG_HOST_BINARY), but forgot to add
the corresponding build-ordr dependency.
Add this missing depenency now.
Additionally, the associated test had an explicit host pkgconf enbled in
its configuration. This is superfluous now that uboot properly depends
on host-pkgconf, so drop that from the test.
Note: it hapenned to work, because host-pkgconf, when explicitly enabled
in the configuration, and without per-package directories, would build
before uboot and thus be available. This would fail with PPD, though,
and thus would break for TLPB.

Migrating the support for this feature to uboot-tools to gain the
ability to build env files when BR2_TARGET_UBOOT isn't selected.
When _ENVIMAGE_SOURCE is not set, we generate a default environment.
However, this default depends on the U-Boot configuration. Therefore,
this can only be done if uboot itself is built as well, and
host-uboot-tools needs to depend on uboot.
For the same reason, the commands for creating the environment have to
be adapted a little. Take this occasion to drastically simplify them.
Note: This patch creates a circular dependency with uboot until the

Before now, U-Boot SPL could only load the Platform Management Unit

U-Boot to load the pm_cfg_obj[1].
Like the PMU firmware, we need a way to pass the PMU cfg to U-Boot

must convert the source file with the tool provided with U-Boot.

U-Boot versions newer than 2020.01 use Python 3.x instead of Python
2.x in various scripts.
We already had the BR2_TARGET_UBOOT_NEEDS_PYLIBFDT and
BR2_TARGET_UBOOT_NEEDS_PYELFTOOLS options, but depending on the U-Boot
version, we now need to indicate if Python 2.x or Python 3.x should be
used.
In addition, it turns out that some U-Boot configurations need a
Python interpreter, without needing pylibfdt or pyelftools. Some of
our defconfigs were abusing the BR2_TARGET_UBOOT_NEEDS_PYLIBFDT option
to make sure a Python interpreter was built.
To solve this issue, we introduce a choice, that let the users specify
what, if any, host python version is needed. The default is 'no', to
preserve the previous behaviour, unless any of the pylibfdt or the
pyelftools options is enabled, in which case we hide the 'no' option,
and use python 2 by default. This dfault is guaranteed by the order of
options in the choice.

Commit baae5156ce (uboot: use local fdt headers) changed the uboot logic
to pass the host include directories with -idirafter instead of -I, so
include files local to u-boot would be preferred over host includes.
This unfortunately breaks configurations using
BR2_TARGET_UBOOT_NEEDS_OPENSSL on hosts with incompatible openssl headers
installed in the system default include directories as explained here:
http://lists.busybox.net/pipermail/buildroot/2018-March/214651.html
The problem is that -idirafter directories gets added to the very end of the
search order, AFTER the system default directories.
Instead use -isystem which causes the directories to be added after -I but
before the system default directories. With this in place, the include
directories of u-boot will first be scanned, followed by the host includes
and finally the system default include directories.

After commit b8c3e94173 ("package/dtc: qemu system build need libfdt")
changed the dtc install target from 'install-bin' to 'install', uboot
compilation failures occurred because libfdt related headers were now
suddenly taken from output/host/include rather than from the uboot sources
itself.
Commit 3a6573ccee ("uboot: use local libfdt.h") solved this by patching
one specific uboot source file, tools/fdtgrep.c, to replace '<...>'-style
includes by '"..."'-style includes.
However, depending on the uboot version, this may not be enough: there may
be other references to fdt header files. In particular taking into account
that it is not uncommon to have vendor-provided uboot trees which have
custom changes.
The root of the problem is that the uboot.mk file passes the host compiler
as follows:
UBOOT_MAKE_OPTS += \
...
HOSTCC="$(HOSTCC) $(HOST_CFLAGS)" \
...
where HOST_CFLAGS contains the string '-I$(HOST_DIR)/include'
The uboot makefiles then use constructs of the form:
$(CC) $(CPPFLAGS) $(CFLAGS) .....
where CPPFLAGS may contain -I references pointing to local directories.
On the expanded compiler command-line, Buildroot's '-I$(HOST_DIR)/include'
is thus present _before_ any -I to local directories, and thus takes
precedence. And that becomes a problem for header files present both
locally as in the Buildroot host directory, which is the case for libfdt.
To fix this problem without having to patch u-boot sources, use '-idirafter'
rather than '-I' to pass the Buildroot host include directory. '-idirafter'
is basically the same thing, but adds the specified directory at the end
of the include precedence chain, rather than at the beginning.

Since 0542bb79e8 (uboot: Support multiple environment source files),
missing user-supplied environment source files is no longer detected.
This is because we cat them all, and feed the concatenation to the stdin
of mkenvimage. So, if one source file is missing, the cat exits in error,
but the compound command exits with the exit code of the last command,
which is that of mkenvimage, which happens to be happy with whatever it
is fed on its stdin, even is empty.
We fix that by creating a temporary file, that we even leave afterward
for the user to inspect.
We also move it out of the _CMDS block and into a macro of its own, so
that it is easier to write and maintain.

Some ARM64 platforms (such as Allwinner A64/H5) have a boot process
where U-Boot encapsulates the BL31 part of the ARM trusted
firmware. For such platforms, we need to build ATF before U-Boot, and
pass a BL31 variable pointing to ATF bl31.bin to the U-Boot build
process.
This commit introduces a BR2_TARGET_UBOOT_NEEDS_ATF_BL31 variable to
achieve this.

[Thomas:
- Rename option to BR2_TARGET_UBOOT_NEEDS_ATF_BL31
- Drop changes to arm-trusted-firmware.mk, they are taken care of by
previous commits.
- Improve Config.in help text
- Add missing dependency on arm-trusted-firmware when
BR2_TARGET_UBOOT_NEEDS_ATF_BL31 is enabled.
- Use bl31.bin from $(BINARIES_DIR) instead of taking it from ATF's
build dir.]
[Peter: depend on toplevel atf option and select bl31 option. Ensure it
cannot be enabled together with ARM_TRUSTED_FIRMWARE_UBOOT_AS_BL33
as that would cause circular dependencies]
