111a8b5735 Merge branch '2021-12-27-CONFIG-migrations' into next
- Merge a large number of CONFIG migration patches.  Most of these are
  taking existing migrations and re-running them.  A few of these needed
  additional minor conversions done first, so that more complex
  dependencies could be expressed.  In the end we now have CI jobs to
  ensure that no migrated symbols are used in board config header files.

2f8a6db5d8 Finish conversion of CONFIG_SYS_CLK_FREQ to Kconfig
In order to finish moving this symbol to Kconfig for all platforms, we
need to do a few more things.  First, for all platforms that define this
to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to
CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h.  This entails
also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk()
and updating a few preprocessor tests.

With that done, all platforms that define a value here can be converted
to Kconfig, and a fall-back of zero is sufficiently safe to use (and
what is used today in cases where code may or may not have this
available).  Make sure that code which calls this function includes
<clock_legacy.h> to get the prototype.

e4c3ce7e28 CONFIG_SYS_CLK_FREQ: Consistently be static or get_board_sys_clk()
This CONFIG option is used in one of two ways.  The first way is that it
is defined to a static value, of an unsigned long size.  The second way
is that it is defined to something, typically a function, to determine
this value at run time.

However, in a few cases that function returns a static value.  Change
that to using the static value directly.

In the case of using something at run time, convert everything to using
a function of the same name and prototype.  This will allow for further
cleanups.

Finally, we have a few cases where the function is just not used, so
drop it.

3847ba94f0 Finish converting CONFIG_WATCHDOG, HW_WATCHDOG and WDT to Kconfig
Because of how these symbols work, and the remaining board config.h file
uses, we need to do these at the same time.  In some cases we just get
to move rather directly to the defconfigs.  A few cases require manual
intervention.

For the case of the eb_cpu5282 we need to select HW_WATCHDOG for the
target, given how it's implemented.

For the cases of m53menlo, dh_imx6, display5, and display5_factory we
disable SPL watchdog support as the particular combination of options
they want would require either more symbols or enabling SPL_DM.

bc0abd80b3 Merge branch '2021-12-23-make-OF_BOARD-a-boolean' into next
Merge v8 of Simon's series to make CONFIG_OF_BOARD a boolean option.
Quoting him:

With Ilias' efforts we have dropped OF_PRIOR_STAGE and OF_HOSTFILE so
there are only three ways to obtain a devicetree:

   - OF_SEPARATE - the normal way, where the devicetree is built and
      appended to U-Boot
   - OF_EMBED - for development purposes, the devicetree is embedded in
      the ELF file (also used for EFI)
   - OF_BOARD - the board figures it out on its own

The last one is currently set up so that no devicetree is needed at all
in the U-Boot tree. Most boards do provide one, but some don't. Some
don't even provide instructions on how to boot on the board.

The problems with this approach were covered in another patch[1], since
removed from this series.

In practice, OF_BOARD is not really distinct from OF_SEPARATE. Any board
can obtain its devicetree at runtime, even it is has a devicetree built
in U-Boot. This is because U-Boot may be a second-stage bootloader and its
caller may have a better idea about the hardware available in the machine.
This is the case with a few QEMU boards, for example.

So it makes no sense to have OF_BOARD as a 'choice'. It should be an
option, available with either OF_SEPARATE or OF_EMBED. This would allow
rpi3, for example, to run with the devicetree provided by the prior
bootloader.

This series makes this change, adding various missing devicetree files
(and placeholders) to make the build work.

To make the 'prior stage' side of things more deterministic, a new
OF_HAS_PRIOR_STAGE is added, which cannot be disabled by updated a board's
defconfig. This should help to prevent mistakes.

It also adds a run-time message showing where the devicetree came from,
as well as warnings if the board's expected flow is not being used. This
comes originally from the 'standard passage' series, which depends on
this series.

It also provides a few qemu clean-ups discovered along the way. The
qemu-riscv64_spl problem is fixed.

Please see [2] for discussion on the v6 series.

I put Heinrich's Tested-by tag[3] for the series onto the three devicetree
patches (ARM and RISC-V) that I think it most affects. It isn't possible
to apply a tag to a whole series at present and in any case there are
changes in v7.

This series is available at u-boot-dm/ofb-working

These warnings should only appear if the board config has been changed, or

b7d8e85b4c fdt: Avoid emitting an device tree when not needed
U-Boot always needs some sort of a device tree in the build. Some boards
never actually use this, at least in production systems, since a prior
firmware stage sets one up and passes it to U-Boot. At present the only
mechanism to do that is with custom function (OF_BOARD), but future work
will include a standard way of doing this ('standard passage').

It can be confusing to see a device tree emitted from the U-Boot build in
this situation. Add an option to drop it.

24f073d400 fdt: Makefile: Ensure that OF_BOARD is used when needed
Boards which define OF_HAS_PRIOR_STAGE must define OF_BOARD at present,
since a custom function is the only way to obtain the devicetree at
runtime.

Add a build error when this requirement is not met, to avoid accepting
any patches which break this requirement.

Add an allowlist for boards which use it, currently none. This allowlist
can be updated for local development, if needed.

239d22c795 fdt: Enable OF_HAS_PRIOR_STAGE for most boards with OF_BOARD
Use this new Kconfig instead of OF_BOARD, so we know for sure which boards
obtain their devicetree from a prior stage. Leave sandbox alone since it
does not. Also don't touch xilinx_versal_virt since it does not have a
specific TARGET Kconfig.

This option implies OF_BOARD for now, but with future work standard
passage may be used instead.
