From: Sascha Hauer @ 2016-07-22 12:44 UTC (permalink / raw)
To: Barebox List
The code in common/boot.c collects the different boot entries in
lists of type struct blspec, eventhough many of them may not be
bootloader spec entries but for example boot scripts. This is the first
step of separating the data structures from boot entries and bootloader
spec: As struct blspec is merely a container for collecting boot entries
We simply rename struct blspec to struct bootentries. No functional change.

We currently have to special case blspec entries vs. boot scripts
in the common boot code since we want to print different informations
about them. This adds a 'title' and 'description' which can be filled
in with different information by bootscripts and blspec entries and
so we get rid of the special handling.

This completes the separation of the blspec code from the boot
code. With this the boot code only handles generic boot entries
of type struct bootentry which are embedded into the type
(blspec/bootscript) specific structs.

Since blspec_boot is now only used locally we can make it static. Move
it up to avoid a static declaration.

bootentries_alloc() is the place where the struct bootentries container
is allocated, so allocate the menu entry there aswell.

We have a struct bootentries type to collect different boot entries,
so use this to pass around data between functions rather than using
an array of strings. With this we also no longer have to convert a
string to a boot entry multiple times.

Normally code in commands/ shall only do the option parsing whereas the
functionality shall be in common/ to make the code usable from C aswell.
Do this in the boot code aswell, move it to common/boot.c and add the
function prototypes to include/boot.h

From: Sascha Hauer @ 2016-07-22 12:44 UTC (permalink / raw)
To: Barebox List
It's nicer to read when target names have quotes around them, it
makes it clear that this is a string passed in somewhere.

When no targets to boot are found it can happen that the boot command
just returns silently. Explicitly print a message in this case to give
a clue what might went wrong.

Normally one should not be interested that the blspec code scans
a directory. In case blspec is not actively used it might even be
confusing, so lower priority of the message in blspec_scan_directory()
to pr_debug.

When doing a 'boot friesel net' one expects a message when 'friesel'
does not give any bootable results and thus 'net' is booted. This patch
adds this message.
