We talk about importing code from other projects in two places. The
first place is in the coding style section, where we explain when to or
not to deviate in terms of white space, etc. In the process
documentation we now add a note about saying where the code was imported
from and to ensure that you do not copy Signed-off-by or other tags.

board: dhelectronics: Implement common MAC address functions
This is a starting point for unifying duplicate code in the DH board
files. The functions for setting up MAC addresses are very similar for
the i.MX6, i.MX8 and stm32mp1 based boards.
All pre-existing implementations follow the same logic:
(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,
ready to be used by board specific files.
Furthermore there is an implementation of (2) for imx based boards.

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.

event: Add an event for device tree fixups
At present there is a confusing array of functions that handle the
device tree fix-ups needed for booting an OS. We should be able to switch
to using events to clean this up.
As a first step, create a new event type and call it from the standard
place.
Note that this event uses the ofnode interface only, since this can
support live tree which is more efficient when making lots of updates.

bootstd: Drop the system bootdev
This was a work-around for the fact that global bootmeths such as EFI
bootmgr and VBE don't use a particular bootdev, or at least select it
themselves so that we don't need to scan all bootdevs when using that
bootmeth.
Simon Glass [Sat, 30 Jul 2022 21:52:28 +0000 (15:52 -0600)]
bootstd: Always create the EFI bootmgr bootmeth
Now that we can separate this out from the normal bootmeths, update the
code to create it always.
We cannot rely on the device tree to create this, since the EFI project
is quite opposed to having anything in the device tree that helps U-Boot
with its processing.

bootstd: Allow scanning for global bootmeths separately
Typically we want to find and use global bootmeths first, since they have
the best idea of how the system should boot. We then use normal bootmeths
as a fallback.
Add the logic for this, putting global bootmeths at the end of the
ordering. We can then easily scan the global bootmeths first, then drop
them from the list for subsequent bootdev-centric scans.
This changes the ordering of global bootmeths, so update the
bootflow_system() accordingly.
Drop the comment from bootmeth_setup_iter_order() since this is an
exported function and it should be in the header file.

for this test.

bootstd: Allow bootmeths to be marked as global
The current way of handling things like EFI bootmgr is a bit odd, since
that bootmeth handles selection of the bootdev itself. VBE needs to work
the same way, so we should support it properly.
Add a flag that indicates that the bootmeth is global, rather than being
invoked on each bootdev. Provide a helper to read a bootflow from the
bootmeth.

Note that we don't permit aliases in this other device tree, since the
of_access implementation maintains a list of aliases collected at
