On some platforms, DDR parts are multi-sourced and the exact part number
used is not know to either kernel or firmware at build time. Firmware
can read identifying information from DDR mode registers at boot time
but needs a way to communicate this information to kernel and/or
userspace. This patch adds optional properties for this information to
the existing "jedec,lpddr3" device tree binding to be used for that
purpose.

The example in video-interfaces.yaml uses a bunch of undocumented
bindings which will cause warnings when undocumented compatible checks
are enabled. The example could be fixed to use documented bindings, but
doing so would just duplicate other examples. So let's just remove the
example.

This converts the BCM4329 family bindings to YAML schema, and
extends and fixes the bindings like this:
- Name the bindings after the first chip (BCM4329) since
wildcards like 43xx are nowadays frowned upon by the DT
binding reviewers. We call this the "BCM4329 family"
- Add compatible strings for all the variants that seem to
exist in the wild. (Derived from firmware listings.)
- Support specific-to-generic compatible strings (as already
in use in DTS files).
- Add required reg property (SDIO function number)
- Add reset-gpios property (some systems wire this to a GPIO
line).
- I have only listed Arend as maintainer for now, volunteers
can be added.

Adding checks for undocumented compatible strings reveals a bunch of
warnings in the DT binding examples. Fix the cases which are typos, just
a mismatch between the schema and the example, or aren't documented at all.
In a couple of cases, fixing the compatible revealed some schema errors
which are fixed.
There's a bunch of others remaining after this which have bindings, but
those aren't converted to schema yet.

Now that fdtoverlay is part of the kernel build, start using it to test
the unitest overlays we have by applying them statically. Create two new
base files static_base_1.dts and static_base_2.dts which includes other
.dtsi files.
Some unittest overlays deliberately contain errors that unittest checks
for. These overlays will cause fdtoverlay to fail, and are thus not
included for static builds.

In order to build-test the same unit-test files using fdtoverlay tool,
move the device nodes from the existing overlay_base.dts and
testcases_common.dts files to .dtsi counterparts. The .dts files now
include the new .dtsi files, resulting in exactly the same behavior as
earlier.
The .dtsi files can now be reused for compile time tests using
fdtoverlay (will be done by a later commit).
This is required because the base files passed to fdtoverlay tool
shouldn't be overlays themselves (i.e. shouldn't have the /plugin/;
tag).
Note that this commit also moves "testcase-device2" node to
testcases.dts from tests-interrupts.dtsi, as this node has a deliberate
error in it and is only relevant for runtime testing done with
unittest.c.

Add a generic rule to apply fdtoverlay in Makefile.lib, so every
platform doesn't need to carry the complex rule. This also automatically
adds "DTC_FLAGS_foo_base += -@" for all base files.
The platform's Makefile only needs to have this now:
foo-dtbs := foo_base.dtb foo_overlay1.dtbo foo_overlay2.dtbo
dtb-y := foo.dtb
We don't want to run schema checks on foo.dtb (as foo.dts doesn't exist)
and the Makefile is updated accordingly.

We update 'always-y' based on CONFIG_OF_ALL_DTBS three times. It would be
far more straight forward if we rather update dtb-y to include all .dtb
files if CONFIG_OF_ALL_DTBS is enabled.

dt-validate has an option to warn on any compatible strings which don't
match any schema. The option has recently been improved to fix false
positives, so let's enable the option. This is useful for tracking
compatibles which are undocumented or not yet converted to DT schema.
Previously, the only check of undocumented compatible strings has been
an imperfect checkpatch.pl check.
The option is enabled by default for 'dtbs_check'. This will add more
warnings, but some platforms are down to only a handful of these
warnings (good job!).
There's about 100 cases in the binding examples, so the option is
disabled until these are fixed. In the meantime, they can be checked
with:
make DT_CHECKER_FLAGS=-m dt_binding_check

kexec_fdt_totalsize_ppc64() includes the base FDT size in its size
calculation, but commit 3c985d31ad ("powerpc: Use common
of_kexec_alloc_and_setup_fdt()") changed the kexec code to use the
generic function of_kexec_alloc_and_setup_fdt() which already includes
the base FDT size. That change made the code overestimate the size a bit
by counting twice the space required for the kernel command line and
/chosen properties.
Therefore change kexec_fdt_totalsize_ppc64() to calculate just the extra
space needed by the kdump kernel, and change the function name so that it
better reflects what the function is now doing.

fdt_appendprop_addrrange() function adds a property, with the given name,
to the device tree at the given node offset, and also sets the address
and size of the property. This function should be used to add
"linux,ima-kexec-buffer" property to the device tree and set the address
and size of the IMA measurement buffer, instead of using custom function.
Use fdt_appendprop_addrrange() to add "linux,ima-kexec-buffer" property
to the device tree. This property holds the address and size of
the IMA measurement buffer that needs to be passed from the current
kernel to the next kernel across kexec system call.

Both arm64 and powerpc do essentially the same FDT /chosen setup for
kexec. The differences are either omissions that arm64 should have
or additional properties that will be ignored. The setup code can be
combined and shared by both powerpc and arm64.
The differences relative to the arm64 version:
- If /chosen doesn't exist, it will be created (should never happen).
- Any old dtb and initrd reserved memory will be released.
- The new initrd and elfcorehdr are marked reserved.
- "linux,booted-from-kexec" is set.
The differences relative to the powerpc version:
- "kaslr-seed" and "rng-seed" may be set.
- "linux,elfcorehdr" is set.
- Any existing "linux,usable-memory-range" is removed.
Combine the code for setting up the /chosen node in the FDT and updating
the memory reservation for kexec, for powerpc and arm64, in
of_kexec_alloc_and_setup_fdt() and move it to "drivers/of/kexec.c".
