Add a bootflow command to update the command line more easily. This allows
changing a particular parameter rather than editing a very long strings.
It is also easier to handle with scripting.
The new 'bootflow cmdline' command allows getting and setting single
parameters.

The Linux command line consists of a number of words with optional values.
At present U-Boot allows this to be changed using the bootargs environment
variable.
But this is quite painful, since the command line can be very long.
Add a function which can adjust a single field in the command line, so
that it is easier to make changes before booting.

Some operating systems have a command line which can be adjusted before
booting. Store this in the bootflow so it can be controlled within
U-Boot.

We use the terms 'distro' to mean extlinux but they are not really the
same. 'Distro' could refer to any method of booting a distribution,
whereas extlinux is a particular method.
Also we sometimes use syslinux, but it is better to use the same term in
all cases.
Rename distro to syslinux and also update bootstd uses of syslinux to use
extlinux instead.

In a few cases the error handling is not quite right. Make sure we
return the actual error in distro_efi_read_bootflow_file() rather than
-EINVAL. Return -IO when a file cannot be read. Also show the error name
if available.
This does not change operation, but does make it easier to diagnose
problems.

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.

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.

We must call dm_scan_other() after devices from the device tree have been

Some tests currently return 0 when they want to be skipped. Update them to

When a FIT includes some OS requests, U-Boot should process these and add
the requested info to corresponding subnodes of the /chosen node. Add a
pytest for this, which sets up the FIT, runs bootm and then uses a C
unit test to check that everything looks OK.
The test needs to run on sandbox_flattree since we don't support
device tree fixups on sandbox (live tree) yet. So enable BOOTMETH_VBE and
disable bootflow_system(), since EFI is not supported on
sandbox_flattree.

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.
Drop the system bootdev entirely.

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.

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 most testing we don't want this bootmeth to actually do anything. For
the one test where we do, add a test hook to obtain the correct behaviour.
This will allow us to bind the device always, rather than just doing it
