The device tree has evolved over time, so re-sync. This also
partial reverts one change on the PCIe, because U-Boot doesn't
have a proper driver. However, since the clock is configured
to generate a 100MHz reference clock by default, a proper driver
isn't really necessary.

One fix makes the reboot more robust on some older board, another one
stabilises the initial clock setup on the A10/A20.
Two patches make sure our DRAM init does not actually change the content
of the DRAM array, which allows to use DRAM for Linux' pstore
functionality.
We get SPI support for U-Boot proper for one more SoC, that patch was
lingering around for a while, and should not affect other SoCs, so I am
merging this now.
As an added bonus, we get the defconfig file for a new board, the DT was
already synced from the kernel tree.
The CI looked happy with changes, and I tested them on five different
boards with different SoCs.
SolidRun Armada-388 SoM has an i2c bus supporting on-som eeprom, and
peripherals on a carrier.
armada-38x.dtsi disables this bus by default, it should be enabled by
som or carrier dts.
Linux has moved i2c0 from helios-4 board dts to som dtsi, including
status, pinctrl and clock speed.
Copy these settings from mainline.
This fixes accessing i2c bus from u-boot commandline.

The OrangePi Zero 2W is a tiny development board featuring the Allwinner
H618 SoC, shipping with up to 4GB of LPDDR4 DRAM, a mini-HDMI connector,
two USB Type-C sockets and a 16MB SPI NOR flash.
There is an FPC connector to connect an expansion board, which sports
two more USB Type-A sockets and a 100MBit Ethernet port. Support for
the expansion board is not in the DT yet, probably a DT overlay would
cover this in the future.
Add a defconfig file selecting the right drivers and DRAM options.
Since the .dts file was synced from the Linux kernel repo already, we
just need to add one line to the Makefile to actually build the .dtb.
The DRAM parameters were derived from the values found in the BSP DRAM
drivers on the SPI NOR flash.

The same U-Boot binary is compatible with multiple Verdin AM62 board
variants. However, some of the SoC models can only operate at a maximum
speed of 1 GHz.
Previously, the boards with lower-speed grades were running at
overclocked speeds, leading to kernel complaints about unsupported
configurations.
To resolve this issue, the operating speed has been decreased to the
maximum allowable value across all Verdin AM62 board variants. As a
result, there is a regression in overall boot time, increasing by around
200 milliseconds for the faster SoC variant.

This series fixes two regressions affecting multiple Toradex boards
(i.MX, TI and TEGRA based) and targets the current master, e.g. v2024.04
release.
U-Boot `reset` command is broken on all Tordex i.MX6* based SoMs since
v2023.07, this series fixes it enabling the `wdt-reboot` driver.
Since v2024.04-rc1 reading the Toradex configuration block is not working
properly anymore, the serial number and the hardware version are not read
correctly, preventing the board from functioning correctly (wrong mac address,
wrong DT, ...). This is fixed by reading the config block in `EVT_SETTINGS_R`
and adding a toradex sysinfo driver. In addition to that, we now use a random
mac address in case the config block is invalid.

Board description describes the hard part of chip (PS) but programmable
logic (PL) part is not described in this file. But clocks on the board are
not only connected to PS but also wired to PL. And because two revisions
are available where revA is using one si5332 and revB multiple clock chips
using the same clock labels helping with keeping only one device tree
overlay which targets PL. That's why synchronize clock labels and use
labels from revB which are more generic.
Unfortunately if there is driver for si5332 chip split could happen again
but it is still worth to do it now and solve this issue when occurs.

re-calibrates the output clock frequency at probe() time based on the NVRAM
