18552d2a72 bootstd: Add a hunter for the extension feature
This needs to run before any bootdev is used, so add a hunter for it.

35ce14617e extension: Refactor to allow non-command usage
The current extension code is designed to be used from commands. We want
to add a boot driver which uses it. To help with this, split the code into
the command processing and a function which actually does the scan.

Really the extension code should be in common/ or use driver model, but
this is a start.

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.

22061d3d2a bootstd: Add a new bootmeth method to set the bootflow
Normally the bootmeth driver reads the bootflow from the bootdev, since
it knows the correct way to do it.

However it is easier for some bootdevs to handle this themselves. For
example, reading from SPI flash is quite different from other devices.

Add a way for the bootdev to pass a bootflow to the bootmeth, so that
this can be supported.

Note that the device tree is not allocated, but instead is stored at

adjusted at some point, but for now it works well and fits in with the

7f33194132 lib: Support printing an error string
It is often useful to show an error code to give the user a clue as to
what went wrong. When error strings are compiled into U-Boot it is
possible to show a message as well.

But at present it is not very convenient, since code must check if the
error strings are present, then obtain the error string and use it in
a printf() string.

Add a %dE option which shows an error code along with an error string,
if available. This makes it easy to show one or both.

3a2cb96e5d dm: mmc: Use bootdev_setup_sibling_blk()
At present MMC uses the bootdev_setup_for_dev() function to set up the
bootdev. This is because MMC only has one block-device child, so does not
need to worry about naming of the bootdev.

However this inconsistency with other bootdevs that use block devices is a
bit annoying. The only real reason for it is to have a name like
'mmc0.bootdev' instead of 'mmc0.blk.bootdev'.

Update bootdev_setup_sibling_blk() to drop '.blk' from the name where it
appears, thus removing the only reason to use the bootdev_setup_for_dev().
