Now that extension support has been added to extlinux and efi bootmeths
we can remove this line from the TODO list.

Add the option to load the bootscript with the tftp command (static IP)
instead of the dhcp command (dynamic IP). For this a new function
tftpb_run similar to dhcp_run, is needed. The selection of which command
to use can be done with the ip_dyn environment variable, which can be
set to yes or no. The ip_dyn variable was chosen as it is already in use
on the imx platforms.
Also edit the bootstd doc.

When there are no more bootdevs we should still go through the global
bootmeths, since some may not have yet been used, if their priority has
not yet come up.
Add a final check for this at the end of the iterator.
Update the documentation to match the new behaviour of global bootmeths.

The documentation of bootmeth rauc in some aspects does not reflect the
real program flow. Specifically the reset of boot tries in case of "no
more slots found" is incorrect (it won't change BOOT_ORDER).
Also the search sequence for boot scripts was mixed and incomplete.
Fix these points in the documentation.
Explain the initial setup of any missing BOOT_ORDER and BOOT_x_LEFT
environment variables, and inform about BOOT_x_LEFT decrementing.

Any 'bootable' flag in a DOS partition causes boostd to only scan
bootable partitions for that media. This can mean that extlinux.conf
files on the root disk are missed.
Put this logic behind a flag and update the documentation.
For now, the flag is enabled, to preserve the existing behaviour of
bootstd which is to ignore non-bootable partitions so long as there is
at least one bootable partition on the disk. Future work may provide a
command (or some other mechanism) to control this.

Add a new 'bootstd images' command, which lists the images which have
been loaded.
Update some existing tests to use it. Provide some documentation about
images in general and this command in particular.
Use a more realistic kernel command-line to make the test easier to
follow.

We have previously added logic to allow a "fallback" option to be
specified in the extlinux configuration. Provide a command that allows
us to set this as the preferred default option when booting.
Combined with the bootcount functionality, this allows the "altbootcmd"
to provide a means of falling back to a previously known good state
after a failed update. For example, if "bootcmd" is set to:
bootflow scan -lb
We would set "altbootcmd" to:
bootmeth set extlinux fallback 1; bootflow scan -lb
Causing the boot process to boot from the fallback option.
