4f806f31fc bootflow: Rename bootflow_flags_t
These flags actually relate to the iterator, not the bootflow struct
itself. Rename them.

0c1413f6d7 test: bootdev: Do not require USB to compile test
This test will block compilation of the entire test suite
on platforms without USB support. Make the extern
"usb_started" conditional on USB host or gadget and
define a dummy flag if neither is enabled.

a950f2855a bootstd: Record the bootdevs used during scanning
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.

4b7cb058df bootstd: Drop the old bootflow_scan_first()
This function is not used outside tests. Drop it and rename
bootflow_scan_dev() since it is how we start a scan now.

91943ff703 bootstd: Allow scanning a single bootdev label
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.

47aedc29dc bootstd: Switch bootdev scanning to use labels
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.

43e89a3069 bootstd: Allow iterating to the next bootdev priortiy
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.

66e3dce787 bootstd: Allow hunting for a bootdev by label
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.

eacc261178 bootstd: Add a new pre-scan priority for bootdevs
We need extensions to be set up before we start trying to boot any of the
bootdevs. Add a new priority before all the others for tht sort of thing.
Also add a 'none' option, so that the first one is not 0.

While we are here, comment enum bootdev_prio_t fully and expand the test
for the 'bootdev hunt' command.

d9f48579dc bootstd: Treat DHCP and PXE as bootdev labels
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.

"spi_flash".

bd90b09288 bootstd: Add the concept of a bootdev hunter
Some bootdevs must be enumerated before they appear. For example, USB
bootdevs are not visible until USB is enumerated.

With standard boot this needs to happen automatically, since we only
want to enumerate a bus if it is needed.

Add a way to define bootdev 'hunters' which can be used to hunt for
bootdevs of a given type. Track which ones have been used and add a
command to list them.

Include a clang work-around which seems to be needed.
