On Zynq, the booloader is responsible for some basic initializations, such as
enabling peripherals, DDR and configuring pinmuxes. The ps7_init_gpl.c file
(and optionally, ps7_init_gpl.h) contains the code for such initializations.
Although U-Boot contains ps7_init_gpl.c files for some boards, each of them
describes only one specific configuration. Users of a different board, or
needing a different configuration, can generate custom files using the Xilinx
Vivado development tools.
This patch adds Buildroot support for custom zynq ps7_init_gpl.c files in the
same way that is already done for zynqmp when working with custom hardware
that is not already supported by u-boot.
To test this feature, the following configs can be added to any zynq_defconfig:
BR2_TARGET_UBOOT_ZYNQ=y
BR2_TARGET_UBOOT_ZYNQ_PS7_INIT_FILE=<path to custom board ps7_init_gpl.c>

u-boot has introduced a new file called qspi.bin for users who boot from a
qspi flash device. It combines the spl/boot.bin and u-boot.itb files into a
single binary that can be written to the qspi flash.
Here is an example of how binman generates the qspi.bin:
a4c9811910
At the moment, the qspi.bin is only used for the zynqmp platform, but other
platforms may adopt it, so the buildroot support has been made in a generic
way.
This patch adds the necessary support for buildroot to install this binary.

user had to select BR2_TARGET_UBOOT_NEEDS_TI_K3_DM in the defconfig

With binman, this option is no longer necessary since

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.

As reported in commit [1] of the U-Boot project, the config.mk file has

be used with recent versions of U-Boot.
The configuration option added by this comit allows the creation of

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

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

So, this commit switches all the kconfig-based package to use 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
