For EFI, the distro boot scripts search in three different directories
for the .dtb file. The SOC-based filename fallback is supported only for
32-bit ARM.
Adjust the code to mirror this behaviour.
Also some boards can use a prior-stage FDT if one is not found in the
normal way. Support this and show a message in that case.

Add a way to record the bootdevs used when scanning for bootflows. This is
useful for testing.
Enable this only with BOOTSTD_FULL and do the same for the progress
reporting.
Re-enable and update the affected tests now that we have this feature.
For bootdev_test_order_default() there is no-longer any support for using
the bootdev aliases to specify an ordering, so drop that part of the test.

This function is not used outside tests. Drop it and rename
bootflow_scan_dev() since it is how we start a scan now.

We want to support scanning a single label, like 'mmc' or 'usb0'. Add
this feature by plumbing the label through to the iterator, setting a
flag to indicate that only siblings of the initial device should be used.
This means that scanning a bootdev by its name is not supported anymore.
That feature doesn't seem very useful in practice, so it is no great loss.
Add a test for bootdev_find_by_any() while we are here.

At present we set up the bootdev order at the start, then scan the
bootdevs one by one.
However this approach cannot be used with hunters, since the bootdevs may
not exist until the hunter is used. Nor can we just run all the hunters at
the start, since that violate's U-Boot's 'lazy init' requirement. It also
increases boot time.
So we need to adjust the algorithm to scan by labels instead. As a first
step, drop the dev_order[] array in favour of a list of labels. Update the
name of bootdev_setup_iter_order() to better reflect what it does.
Update some related comments and log messages. Also disable a few tests
until a later commit where we can use them.

Add a function which moves to the next priority to be processed.
This works by storing the current priority in the bootflow iterator. The
logic to set this up is included in a subsequent commit.

Add a function which moves to the next label in a list of labels. This
allows processing the boot_targets environment variable.
This works using a new label list in the bootflow iterator. The logic to
set this up is included in a subsequent commit.

Add a function to hunt for a bootdev label and find the bootdev produced
by the hunter (or already present).
Add a few extra flags so that we can distinguish between "mmc1", "mmc" and
"1" which all need to be handled differently.

Add a flag to control whether hunters are used when scanning for
bootflows. Enable it by default and tidy up the flag comments a little.
Fow now this has no effect, until a future patch enables this feature.

These are associated with the ethernet boot device but do not match its
uclass name, so handle them as special cases.
Provide a way to pass flags through with the bootdev so that we know
how to process it. The flags are checked by the bootmeths, to ensure that
only the selected bootmeth is used.
While these both use the network device, they work quite differently. It
is common to run only one of these, or to run PXE before DHCP. Provide
bootflow flags to control which methods are used. Check these in the two
bootmeths so that only the chosen one is used.

Add a bootdev for SPI flash so that these devices can be used with
standard boot. It only supports loading a script.
Add a special case for the label, since we want to use "spi", not
"spi_flash".
Enable the new bootdev on sandbox.

This environment variable is supposed to be set so that the script knows
which partition holds the script. Set it before invoking the script.

Some bootmeths provide a way to load a device tree as well as the base
OS image. Add a way to store this in the bootflow. Update the
'bootflow info' command to show this information.
Note that the device tree is not allocated, but instead is stored at
an address provided by an environment variable. This may need to be
adjusted at some point, but for now it works well and fits in with the
existing distro-boot scripts.

At present all partitions are scanned, whether marked bootable or not.
Use only bootable partitions, defaulting to partition 1 if none is
found.

Create an expo to handle the boot menu. For now this is quite simple, with

Add the concept of an OS name to the bootflow. This typically includes the
OS name, version and kernel version.
Implement this for the distro and script bootmeths so that it works with
Armbian and older version of Fedora.

Add support for handling this concept in bootflows. Update the 'bootflow'
command to allow only the normal bootmeths to be used. This alllows
skipping EFI bootmgr and VBE, for example.

A bootflow encapsulates the process used to boot an operating system.
It typically has a control file (such as extlinux.conf) and information
about which 'bootdev' it came from.
Add the header file for this first, since it is needed by all other
files.
