If of_state_fixup() fails for some reason, boot/bootm will fail, too
However, it is completely unclear where the error has happened, and to
the user it rather seems like the kernel device tree loaded from some
file was broken/corrupt, not that in fact some fixup routine was
failing.
Adding a meaningful error message can help debugging significantly.

There are several use cases where a redundant Linux system is needed. The
barebox,bootstate framework provides the building blocks to model different
use cases without the need to start from the scratch over and over again.

When bootloader spec is used to boot devices it is often desirable
to boot the same image from different media. Since the fs images
need to contain the root= parameters to tell Linux where to boot
from the images can't be identical on different media.
This patch changes this by introducing a 'appendroot' option for
bootloader spec. If set to true, barebox will construct a Linux
commandline option for the device the bootloader spec entry is found
on.

Support for default/once entries was lost earlier. This fixes this
and also looks for default/once entries in the loader directory instead
of the loader parent directory. This keeps the bootloader spec files
together under a common loader directory.

This patch improves the backend property, it can be either a phandle or a
of_path. During probe() of the state driver the backend property is
dereferenced and the resulting of_path is saved in the state context. In a
later patch it will be used to generate a phandle reference to the backend
during DT fixup.

PBL_CONSOLE option is used only for building PBL. See this output:

PBL_CONSOLE looks confusing in PBL-less configuration
so it's better to enable it only if PBL is enabled.

This patch adds a framework to describe, access, store and restore a set of
variables. A state variable set can be fully described in a devicetree node.
This node could be part of the regular devicetree blob or it could be an extra
devicetree solely for the state. The state variable set contains variables of
different types and a place to store the variable set.
For more information see:
