Currently we allow and explicitly check a single shared page with

However there's no way for us dynamically discover the number of pages we

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.

mechanism to do that is with custom function (OF_BOARD), but future work
will include a standard way of doing this ('standard passage').

correlation is not 1:1, since that option simply means that the board has
a custom mechanism for obtaining the device tree. For example, sandbox
defines OF_BOARD. Also the board_fdt_blob_setup() function can in fact
make use of the devicetree in U-Boot if it wishes, as used by
