The partition layout is board-specific, so only the barebox partitions
need to be in the fixed location expected by the MLO code.

We need to wait some time between activating the ethernet and
being able to send the first frame. I have not investigated why
that is the case.
Fixes: SYS#488
UBI devices used to show up with a dynamically assigned number
which is bad for scripting. After a 'ubiattach' a script cannot
know the number of the ubi to continue with. Change this to use
the parent mtd name and extend it with ".ubi".

The ubi number is a dynamically assigned number, so once multiple
ubis are attached, scripts cannot know the ubi number they want
to detach anymore. Convert the ubidetach command to take the mtd
device file instead which is the same argument that was previously
passed to ubiattach.

state must be loaded after the nand driver, otherwise it fails because the
backend is missing. For similar reasons bootstate must come after state.
Move them to the late stage until barebox can do deferred probing.

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.

Although there is the define RAW_BACKEND_COPIES, the state_backend_raw_save()

by looping over all copies, but saving the one we're read from at the end.

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.
