the i.MX6, i.MX8 and stm32mp1 based boards.

(1) Check if ethaddr is already set in the environment
(2) If not, try to get it from a board specific location (e.g. fuse)
(3) If not, try to get it from eeprom

After this commit, (1) and (3) are implemented as common functions,

Merge branch '2022-08-11-verified-boot-for-embedded-initial-support'

To quote Simon:
This adds the concept of a VBE method to U-Boot, along with an
implementation of the 'VBE simple' method, basically a simple way of
updating firmware in MMC from userspace and monitoring it from U-Boot.

VBE simple is implemented in fwupd. U-Boot's role is to set up the
device tree with the required firmware-update properties and provide the
developer with information about the current VBE state. To that end this
series includes a new 'vbe' command that allows VBE methods to be listed
and examined.

As part of this work, support for doing FDT fixups via the event interface
is provided, along with the ability to write to the device tree via the
ofnode interface.

Another (significant) change is that bootmeths now have a 'global' flag,
to allow the implementation of EFI bootmgr (and VBE) to be cleaned up.
The 'system' bootdev is no-longer needed and these bootmeths are scanned
first.

Further work is needed to pull everything together, but this is a step
along the way.

When booting an OS we may obtain a different device tree and want to
modify it. Add some initial support for this into the ofnode API.

Note that we don't permit aliases in this other device tree, since the

arm: mvebu: turris_omnia: Add support for design with SW reset signals

New Turris Omnia HW board revision requires that software controls
peripheral reset signals, namely PERST# signals on mPCIe slots, ethernet
phy reset and lan switch reset. Those pins are connected to MCU controlled
by MCU i2c API as GPIOs. On new HW board revision those pins stay in reset
after board reset and software has to release these peripherals from reset
manually. MCU announce this requirement by FEAT_PERIPH_MCU bit in
CMD_GET_FEATURES command.

On older HW board revisions when FEAT_PERIPH_MCU is not announced, all
those reset signals are automatically released after board finish reset.

Detect FEAT_PERIPH_MCU bit in board_fix_fdt() and ft_board_setup()
functions and insert into device tree blob pcie "reset-gpios" and eth phy
"phy-reset-gpios" properties with corresponding MCU gpio definitions.
PCIe and eth PHY drivers then automatically release resets during device
initialization. Both U-Boot and Linux kernel drivers support those device
tree reset properties.

Initialization of lan switch on new HW board revision is more complicated.
Switch strapping pins are shared with switch RGMII pins. And strapping pins
must be in specific configuration after releasing switch reset. Due to pin
sharing, it is first required to switch A385 side of switch pins into GPIO
mode, set strapping configuration, release switch from reset and after that
switch A385 pins back to RGMII mode.

Because this complicated setup is not supported by switch DSA drivers and
cannot be expressed easily in device tree, implement it manually in SPL
function spl_board_init(). So in proper U-Boot and OS/kernel would be lan
switch initialized and be in same configuration like it was on old HW board
revisions (where reset sequence did those steps at hardware level).
