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.

At present this override function is called even when OF_BOARD is not
enabled. This makes it impossible to disable this feature and in fact
makes the OF_BOARD option useless.

Reinstate its intended purpose, so that it is possible to switch between

- Align90 set to 0x58 - this is the sample point in the receiver, after
the clock is recovered this sampler samples at the chosen value, usually
it is supposed to be 0x60(which is the center of the eye), but sometimes
after adding jitter and ISI the center of the eye can move slightly and
the sample point is not necessarily the exact center, and after
optimization (searching the middle of the eye manually) it was seen that
the center of the eye is actually 0x58 and not 0x60.

- Change the resolution of the DFE to 0x3 which is 6mV(highest
resolution) , this avoids the DFE to saturate and cease to work.

- HPF set to 0x3 which is 5Khz high pass filter, the function of the HPF
is to filter the low frequency patterns(below 5Khz) to make sure that
the signal is not a noise, the setting before was 0x1(205Khz), and the
change came since the USB3 CP0 pattern, that is used in the USB3 jitter
tolerance testing, is similar to PRBS15, which has 2^15=32768bits which
is 32768*200ps (200ps is one Unit interval in USB3(5Gbps)) = 6.5us,
which is in frequency terms: 152Khz. since the PRBS15 is a random
pattern and can theoretically have once in a while a pattern that will
be at frequency of 152Khz, hence the previous setting (205khz HPF) can
possibly filter this pattern which can cause to an error in the
receiver, thus this change to avoid such scenarios.

arm: mvebu: a38x: serdes: fix serdes config for USB3

The electrical serdes configuration for USB3 expects an array as data
argument. For USB3 the second value is used (see data_arr_idx = USB3 =
1). However, because only one value is inside the array mv_seq_exec is
accessing an invalid element and the serdes is configured wrongly.

This wrong initialization is leading to an unreliable detection
mechanism for some USB3 devices. We were able to reproduce the issue
regularly with an LTE modem from Sierra Wireless (SM7455) where it was
not detected as USB3 device in 1/3 of all tests.

This commit fixes the issue by setting data_arr_idx to 0. This is the
same value as the original U-Boot from Marvell is using. There it is
called FIRST_CELL which is a define for 0.
