The commit mentioned in Fixes broke the
CONFIG_DEVICE_TREE_INCLUDES feature, with the result that any board
setting any non-empty value for that fails to build.

The parent of the mentioned commit refactoring a bit by introducing
the dtsi_include_list variable and changing cmd_dtc to loop over that
was fine.

However, the .dtsi files mentioned in CONFIG_DEVICE_TREE_INCLUDES are
not supposed to be generated via the build system. They are meant for
e.g. including a public key for verified boot (generated with the
key2dtsi script), or for injecting some stuff to the /config
node (say, a bootcmd or a load-environment setting or things like
that). The files can either live in-tree in a private branch or
completely outside, e.g. in some Yocto metadata.

But regardless, U-Boot's build system will never know anything about
them, so when the mentioned commit did

dtsi_include_list_deps = $(addprefix $(obj)/,$(subst $(quote),,$(dtsi_include_list)))

things broke, because if CONFIG_DEVICE_TREE_INCLUDES is for example
"/path/to/public_key.dtsi", this would add a dependency on
$(obj)//path/to/public_key.dtsi to each $(obj)/*.dtb target, yielding

make[3]: *** No rule to make target 'arch/arm/dts/imx6dl-aristainetos2c_7.dtb', needed by 'dtbs'.  Stop.

To fix that while preserving the introduced
CONFIG_EFI_CAPSULE_ESL_FILE behaviour, disentangle
CONFIG_DEVICE_TREE_INCLUDES from dtsi_include_list from which
dtsi_include_list_deps is built, and instead just add the items
directly to the $(foreach) loop.

For decoding RISC-V dumps we need to update the script.

This is a subset of my previous arm64_be work.

I wish this could be merged first so it would be easier to work
against xtensa and arm64 be support.

So CONFIG_SYS_BIG_ENDIAN is our cross architecture option for
selecting machine endian, while the old CONFIG_CPU_BIG_ENDIAN
is defined by Arc only.

Use it whenever possible to ensure big endian code path is enabled
for all possible big endian machines.

Fixes: f86ca5ad8f7 ("Introduce Verifying Program Loader (VPL)")

Add the STACKPROTECTOR symbols to the script that generates the
symbols that should not be removed by the use of LTO when linking
a shared object. This prevents a fail to build due to link errors.

This is a followup to the patches that landed in 2024.01 and nearly
made sure that source files for producing .dtbo files use the .dtso
extension. In the same release, a few new .dts files snuck in, and
there was also some test code involving .dtbo -> .dtbo.S -> .dtbo.o I
didn't really know how to handle at the time. This should finish the
job, bring us in sync with linux (at least in this respect), and drop
the .dts -> .dtbo build rule.

[equivalent to linux commit 81d362732bac]

As a follow up to the series allowing DTB overlays to built from .dtso
files. Now that all overlays have been renamed, remove the ability to
build from overlays from .dts files to prevent any files with the old
name from accidental being added.

[linux commit 941214a512d8, modified for U-Boot by removing the
include of vmlinux.lds.h and replacing STRUCT_ALIGNMENT by 16.]

DTB files can be built into the kernel by converting them to assembly
files then assembling them into object files. We extend this here
for DTB overlays with the .dtso extensions.

We change the start and end delimiting tag prefix to make it clear that
this data came from overlay files.
