3a83960b76 doc: add documentation for gen_compile_commands.py
This documentation briefly explains what is a compilation database,
and how to use the script to generate one.

This is not a portage, as there was no original documentation in the
Linux sources.

Acknowledge the documentation in the script's header and in doc/build
index.

c852f2e74c scripts: Port Linux's gen_compile_commands.py to U-Boot
This script generates a database of compiler flags, namely
compile_commands.json. It is quite useful for text editors that use
clangd LSP (e.g. Vim, Neovim).

It was ported from Linux's sources:
- tag: v6.4
- revision 6995e2de6891c724bfeb2db33d7b87775f913ad1

Modifications for U-Boot compatibility will be added in a follow-up
commit.

c7d4dfcd14 scripts/Makefile.lib: Embed capsule public key in platform's dtb
The EFI capsule authentication logic in u-boot expects the public key
in the form of an EFI Signature List(ESL) to be provided as part of
the platform's dtb. Currently, the embedding of the ESL file into the
dtb needs to be done manually.

Add a target for generating a dtsi file which contains the signature
node with the ESL file included as a property under the signature
node. Include the dtsi file in the dtb. This brings the embedding of
the ESL in the dtb into the U-Boot build flow.

The path to the ESL file is specified through the
CONFIG_EFI_CAPSULE_ESL_FILE symbol.

2f27405902 scripts/Makefile.lib: change spelling of $(srctree)/arch/$(ARCH)/dts in dtc_cpp_flags
Currently, all in-tree .dts files (apart from some under test/ and
tools/), reside in arch/$ARCH/dts. However, in the linux kernel tree,
dts files for arm64 boards, and probably in the not too distant
future [1], arm boards as well, live in subdirectories of that.

For private forks, using a vendor or project subdirectory is also more
convenient to clearly separate private code from upstream - in the
same way that code under board/ is also split and easy to maintain.

In order to prepare for us to follow suit and do the splitting of the
in-tree .dts files, and to make life a little easier for private forks
that already place dts files not directly in arch/$ARCH/dts, change
the $(srctree)/arch/$(ARCH)/dts path to instead refer to the directory of
the .dts file being compiled. This should be a no-op for all existing
cases.

a0f9a77912 kbuild: Allow DTB overlays to built from .dtso named source files
[Linux commit 363547d2191c]

Currently DTB Overlays (.dtbo) are build from source files with the same
extension (.dts) as the base DTs (.dtb). This may become confusing and
even lead to wrong results. For example, a composite DTB (created from a
base DTB and a set of overlays) might have the same name as one of the
overlays that create it.

Different files should be generated from differently named sources.
 .dtb  <-> .dts
 .dtbo <-> .dtso

We do not remove the ability to compile DTBO files from .dts files here,
only add a new rule allowing the .dtso file name. The current .dts named
overlays can be renamed with time. After all have been renamed we can
remove the other rule.

[Import notes: Adapt to U-Boot by using the cmd_dtco function instead
of cmd_dtc just like the current .dts -> .dtbo rule.]

6923f49d3a scripts/Makefile.dts: tweak logic for deciding which dtbs to build
The idea in 3609e1dc5f (dts: automatically build necessary .dtb
files) was fine, but the implementation was suboptimal due to some
misunderstandings on my part (and possibly defects in some defconfig
files):

- Sometimes DEFAULT_DEVICE_TREE is not included in OF_LIST or
  SPL_OF_LIST

- SPL_OF_LIST is not always a subset of OF_LIST

- While SPL_OF_LIST governs the list of dtbs relevant to SPL (i.e.,
  may be built into an
  SPL-with-bunch-of-dtbs-to-choose-between-at-runtime), those dtbs are
  not actually _built_ during the SPL build phase, i.e. when $(SPL_)
  would expand to SPL_. fdtgrep runs on the artifacts produced during
  the ordinary U-Boot build.

Tweak the logic so that we simply add the union of all dtbs mentioned
in either DEFAULT_DEVICE_TREE, OF_LIST and SPL_OF_LIST to dtb-y. That
should, for real, ensure that we always build all the dtbs that is
relevant to the current board, and should in turn enable us to
massively simplify arch/*/dts/Makefile.

f07381529b scripts: dtc-version: support git version strings too
Building dtc from git causes the version number to start with a 'v'
(e.g. v1.7.0). printf then fails to parse 'v1' as a decimal value, and
prints '000700' instead of '010700'. Subsequently, the build fails,
because '000700' is less than the required '010400' version.

ed82586c40 sunxi: remove unused CONFIG_MMC_SUNXI_SLOT
There is a CONFIG_MMC_SUNXI_SLOT definition in our sunxi_common.h config
header, which was used to note the first MMC controller to initialise.
The definition in that header was always set to 0, with no easy way of
overriding this, and certainly none of the existing boards made any use
of that (non-)feature.
Remove that definition and replace it with a constant 0 in the only
user, in board.c. It turns out that this is safe, as this is only used
in the SPL, and the BROM also unconditionally initialises MMC0.
This also removes the last legacy config symbol with SUN*I in it from
the whitelist.
