As suggested by Arnout during the review [1], we can assume that U-Boot
needs ti-k3-boot-firmware when it is selected (likely by
ti-k3-r5-loader).
We can remove BR2_TARGET_UBOOT_NEEDS_TI_K3_BOOT_FIRMWARE without
legacy handling since this option is not part of any Buildroot
release.

Previoulsy (without binman), when a TI K3 SoC using Combined binary
with a split firmware boot method was used (am62ax or am62x) [1], the
user had to select BR2_TARGET_UBOOT_NEEDS_TI_K3_DM in the defconfig
to provide Device Manager firmware provided by ti-k3-boot-firmware.
With binman, this option is no longer necessary since
ti-k3-boot-firmware package is already in the u-boot dependency and the
path to DM and SYSFW binaries are provided by BINMAN_INDIRS.
We are going to remove ti-k3-image-gen, so binman is now mandatory on
all TI K3 SoCs.

Recent version of U-Boot use binman to provide a mechanism for building
images, from simple SPL + U-Boot combinations, to more complex
arrangements with many parts.
This tool uses additional host python modules that must be provided by
Buildroot. So introduce a new option BR2_TARGET_UBOOT_USE_BINMAN to
add additional host packages in U-Boot build dependency to use binman.
The binman requirement is directly included in buildman dependency
(tools/buildman/requirements.txt) since within U-Boot, binman is
invoked by the build system, here buildman [1].

BR2_TARGET_UBOOT_NEEDS_TI_K3_DM option has been introduced initially to
support certain TI K3 devices such as AM62x and AM62Ax that require a
Device Manager (DM) firmware.
This option needs to be renamed to use a more generic name in order
to cover further TI K3 SoCs support along with the new u-boot binman
tool that will be added in followup patch. With binman enabled in
u-boot on TI K3 SoC, ti-k3-boot-firmware is needed at buildtime to
provide ti-sysfw (System Firmware) for all TI K3 SoC along with Device
Manager (DM) firmware for AM62x and AM62Ax devices.
With binman support enabled, we don't need to provide the path of the
Device Manager firmware anymore (see [2]).
We can remove DM="<DM firmware>.xer5f" from UBOOT_MAKE_OPTS.
It also means that we can also remove BR2_TARGET_UBOOT_TI_K3_DM_SOCNAME
used to define DM path.
DM=$(BINARIES_DIR)/ti-dm/$(UBOOT_TI_K3_DM_SOCNAME)/ipc_echo_testb_mcu1_0_release_strip.xer5f
For now, keep BR2_TARGET_UBOOT_TI_K3_DM_SOCNAME and DM only when
ti-k3-image-gen is used. We need to update ti_am62x_sk_defconfig
to use binman before removing them along with ti-k3-image-gen.

Certain TI K3 devices such as AM62x and AM62Ax require a Device Manager

As reported in commit [1] of the U-Boot project, the config.mk file has
been suppressed in order to use binman to manage FIT
generation. Therefore, the "u-boot.stm32" make target should no longer
be used with recent versions of U-Boot.
The configuration option added by this comit allows the creation of
the u-boot.stm32 image for both recent versions of U-Boot, which use
binman, and older versions.
Legacy handling would have suggested that this new option should
"default y" to preserve existing behavior, but as moving forward all
U-Boot new versions will no longer need this u-boot.stm32 target, it
probably makes sense here to not comply with this backward
compatibility rule, as an exception.

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.

However, it was not consistently used and handled by the

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

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.
