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.

support for reading from a network also, using DHCP with autoload.

The controller indicates the number of ports but also has a port map
which specifies which ports are actually valid. Make use of this to
avoid trying to send commands to an invalid port.
This avoids a crash on some controllers.

Sometimes ethernet devices are attached to PCI. Since it is quick to scan,
add this into the ethernet hunter.
Run dhcp to establish the network connection. Drop this from the bootdev
since that is not needed now. Update a log message for clarity.

At present this must be done by executing the command. Also it involves
fiddling with the environment to determine the correct autoload behaviour.
Ideally it should be possible to run network operations without even
having the command line present (CONFIG_CMDLINE).
For now, add a function to handle DHCP, so it can be called from a bootdev
more easily.

Add a way to run a bootdev hunter to find bootdevs of a certain type. Add
this to the 'bootdev hunt' command. Test for this are added in a later

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.

When this fails it can be time-consuming to debug. Add some debugging

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.

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().
Switch MMC over to the subling function.

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

device.

behaviour.

At present this test sets up a partition table on mmc1. But this is used
by the bootstd tests, so it is not possible to run those after this test
has run, without restarting the Python test harness.
This is inconvenient when running tests repeatedly with 'ut dm'. Move the
test to use mmc2, which is not used by anything.

When running multiple tests the mmc emulator calls malloc() to obtain the
memory for its disk image. Since the memory is not cleared, it is possible
that it happens to contain a partition table.
The dm_test_part() test (for one) relies on mmc0 being empty on startup.
Zero the memory to ensure that it is.

There is no point in trying to match the alias order for bootdevs, since
build_order() either sorts them by priority, uses the boot_targets
environment variable or the bootdev-order property.
Just use the iterator instead, to simplify the code.

Rather than implement this as its own case in build_order(), process the
boot_targets environment variable in the bootstd_get_bootdev_order()
