bootstd: Adjust the default bootmeth order

2023-08-28T19:59:22+00:00

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.

bootstd: Treat DHCP and PXE as bootdev labels

2023-01-23T23:11:41+00:00

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.

bootstd: Support reading a script from network or SPI flash

2023-01-23T23:11:41+00:00

At present this bootmeth only supports a block device and the sandbox
host filesystem. Add support for obtaining the script from a network
device. Also implement the set_bootflow() method so that it is easy
for other bootdevs (such as enabling SPI flash to support scripts).

bootstd: Set the distro_bootpart env var with scripts

2023-01-23T23:11:40+00:00

This environment variable is supposed to be set so that the script knows
which partition holds the script. Set it before invoking the script.

bootstd: Rename bootdev checkers

2023-01-23T23:11:40+00:00

These functions return 0 if the check passes, so the names are somewhat
confusing. Rename them.

bootstd: Allow reading a logo for the OS

Some operating systems provide a logo in bmp format. Read this in if
present so it can be displayed in the menu.

bootstd: Read the Operating System name for distro/scripts

2023-01-16T23:26:50+00:00

Add the concept of an OS name to the bootflow. This typically includes the
OS name, version and kernel version.

Implement this for the distro and script bootmeths so that it works with
Armbian and older version of Fedora.
