3b58de4d0b Mark DISTRO_DEFAULTS as deprecated
Standard boot has been in place for a while now. Quite a few problems
have been found and fixed. It seems like a good time to mark the
script-based approach as deprecated and encourage people to use standard
boot.

Update the DISTRO_DEFAULTS Kconfig to encourage people to move to
standard boot, which is able to boot Linux distributions automatically.

Add a short migration guide to make this easier.

5986d46f8e bootstd: Adjust the default bootmeth order
The existing distro scripts check extlinux and scripts before EFI. Adjust
the default ordering to do the same, to avoid breaking existing flows.

Add some documentation, mentioning that this order will likely change in
future.

831405f41d bootstd: Support bootmeths which can scan any partition
Some bootmeths support scanning a partition without a filesystem on it.
Add a flag to support this.

This will allow the ChromiumOS bootmeth to find kernel partition, which
are stored in a special format, without a filesystem.

d7d78576bb bootstd: Rename bootdev_setup_sibling_blk()
This name is a little confusing since it suggests that it sets up the
sibling block device. In fact it sets up a bootdev for it. Rename the
function to make this clearer.

79f663515a bootstd: Rename distro and syslinux to extlinux
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.

22353fa6b5 bootstd: Add some default filesystems and commands
We need to support a basic set of filesystems for booting to work in most
cases. Add these in via a new option, letting the board disable them
individually (for space reasons) if desired.

This enables the filesystem commands as well as the actual functionality,
even though bootstd is quite happy to use ext4 without the ext4 command.
Further work would be needed to disintangle this and reduce code size.

Add several other options as well, providing sensible defaults.

We cannot enable this by default, since it expands the size of many
boards quite a lot.

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.
