The SPL code now already parses kwbimage v1 headers where all necessary
information about how to load and execute U-Boot proper is present. The
legacy 64-byte U-Boot header is not used anymore.
Remove this 64-byte header by putting u-boot.bin binary (instead of
u-boot.img) into kwbimage v1 and let SPL code or BootROM to load U-Boot
directly at its execution address.

The data part of v1 kwbimage currently contains U-Boot binary prepended
by 64 bytes long Legacy U-Boot image header. This means that the load
address is currently substracted by 64 bytes to ensure that U-Boot's
entry point is at specified execution address.
As mkimage has already separate arguments for load (-a) and execution
(-e) address, there is no need to derive fixed load address from
execution address.
Therefore remove this load address hack from the kwbimage tool and
support generating v1 kwbimage with arbitrary addresses for load and
execution.
Finally, calculate correct load address by caller for mkimage tool in
Makefile. File u-boot-spl.kwb is always a v1 kwbimage and it is the only
v1 kwbimage which U-Boot's build system generates.
Remove also useless overwriting of destaddr for /binary.0 to the value
which is already set on previous lines.

With LTO activated, the buildman tools failed with an error on my

It seems the shell variable initialization NM=$(NM) is not correctly

I don't found the root reason of the problem but I solve it by

BIOS Release Date must be in format mm/dd/yyyy and must be release date.
U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is
generated from current build timestamp.
Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is
better approximation of U-Boot release date than current build timestamp.
Current U-Boot versioning is in format yyyy.mm so as a day choose 01.
Some operating systems are using BIOS Release Date for detecting when was
SMBIOS table filled or if it could support some feature (e.g. BIOS from
1990 cannot support features invented in 2000). So this change also ensures
that recompiling U-Boot from same sources but in different year does not
change behavior of some operating systems.
Macro U_BOOT_DMI_DATE is not used in other file than lib/smbios.c
so remove it from global autogenerated files and also from Makefile.

As the deadline for migration to DM_USB, when using a USB host
controller has now gone two years past the deadline, enforce migration.
This is done by:
- Ensuring that all host controller options (other than the very legacy
old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and
OF_CONTROL.
- Remove other parts of Kconfig logic that had platforms pick DM_USB.
- To keep Kconfig happy, have some select statements test for USB_HOST
as well.
- Re-order some Kconfig entries and menus so that we can cleanly pick
host or gadget roles. For the various HCD options that have platform
glue options, group them together and update dependencies in some
cases.
- As SPL_DM_USB is not required, on platforms that had not yet enabled
it, disable it.

Some toolchains are compiled so that they pass a --build-id=something
parameter to the linker implicitly.
This causes U-Boot LTO linking to fail with something like:
ld: section .note.gnu.build-id LMA ... overlaps section .text LMA ...
because U-Boot's link scripts do not currently handle .note.gnu.build-id
section.
Fix this by explicitly disabling build-id.

Add plumbing for building U-Boot with Link Time Optimizations.
When building with LTO, $(PLATFORM_LIBS) has to be in --whole-archive /
--no-whole-archive group, otherwise some functions declared in assembly
may not be resolved and linking may fail.
Note: clang may throw away linker list symbols it thinks are unused when
compiling with LTO. To force these symbols to be included, we refer to
them via the __ADDRESSABLE macro in a C file generated from compiled
built-in.o files before linking.

Currently we use incremental linking (ld -r) to link several object
files from one directory into one built-in.o object file containing the
linked code from that directory (and its subdirectories).
Linux has, some time ago, moved to thin archives instead.
Thin archives are archives (.a) that do not really contain the object
files, only references to them.
Using thin archives instead of incremental linking
- saves disk space
- apparently works better with dead code elimination
- makes things easier for LTO
The third point is the important one for us. With incremental linking
there are several options how to do LTO, and that would unnecessarily
complicate things.
We have to use the --whole-archive/--no-whole-archive linking option
instead of --start-group/--end-group, otherwise linking may fail because
of unresolved symbols, or the resulting binary will be unusable.
We also need to use the P flag for ar, otherwise final linking may fail.

Versions of U-Boot before 2014.01 created a symlink from include/asm to
the architecture-specific header directory.
If an ARM board is build with that old version, then sandbox is built on
a more recent version (both with in-tree builds), the include/asm symlink
confuses the build system. It picks up the ARM headers when it should be
using the sandbox ones.
Since 2014 U-Boot has only created a symlink inside the include/asm/
directory and only for out-of-tree builds. So for in-tree builds it does
not expect to see an include/asm symlink. It is not removed by
'make mrproper'. It does show up with 'git status' but is easy enough to
miss.
Add include/asm to the files to remove with 'make mkproper'. For recent
U-Boot builds this has no effect, since include/asm is a directory, not a
file. If the include/asm symlink is there, it will be removed.

Python3 taken from the PATH causes build issues when pylibfdt bindings are
generated with Yocto SDK.
Python3 provided as a part of SDK is not compatible with host Python3,
therefore binding build breaks with following errors:
scripts/dtc/pylibfdt/libfdt_wrap.c:154:11: fatal error: Python.h: No such file or directory
154 | # include <Python.h>
| ^~~~~~~~~~
Do not enforce the python3 from the PATH and make it conditionally-assigned
so it can be overridden from outside of build system. Keep the default
assignment to point to version that is taken from the PATH.
Similar fix has been introduced in b48bfc74ee ("tools: allow to override
python"), where conditional assignment is used for python executable to
address similar build errors.

When CONFIG_USE_DEFAULT_ENV_FILE=y and the file
CONFIG_DEFAULT_ENV_FILE is empty (or at least doesn't contain any
non-comment, non-empty lines), we end up feeding nothing into xxd,
which in turn then outputs nothing. Then blindly appending ", 0x00"
means that we end up trying to compile (roughly)
const char defaultenv[] = { , 0x00 }
which is of course broken.
To fix that, change the frobbing of the text file so that we always
end up printing an extra empty line (which gets turned into that extra
nul byte we need) - that corresponds better to the binary format
consisting of a series of key=val nul terminated strings, terminated
by an empty string.
