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 makes it easier to share the code with linux, on Linux the ease and
write size have to be aligned. Use stride (which is already aligned to erase
block size) during erase, align size_full to writesize and use it while
writing.

Although there is the define RAW_BACKEND_COPIES, the state_backend_raw_save()
function silently assumes exactly two copies. This patch removes that assumtion
by looping over all copies, but saving the one we're read from at the end.

This patch registeres a DT fixup, that copies the statate nodes from the active

[ukl: add call to of_unregister_fixup]
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.

This patch adds the functionality to export the description of the state, but
not the contents of the variables to a DT node. This will be used in a later
patch to "copy" the state description to the kernel device tree during DT
fixup.

This function is needed when a device that already registered a fixup in
the probe routine fails later to probe completely. Without unregistering
the fixup the function might later be called with invalid data.

PBL_CONSOLE option is used only for building PBL. See this output:
barebox$ git grep PBL_CONSOLE
arch/arm/configs/tx28stk5_defconfig:CONFIG_PBL_CONSOLE=y
common/Kconfig:config PBL_CONSOLE
common/Makefile:pbl-$(CONFIG_PBL_CONSOLE) += memory_display.o
include/printk.h: (defined(__PBL__) && defined(CONFIG_PBL_CONSOLE))
include/stdio.h: (defined(__PBL__) && defined(CONFIG_PBL_CONSOLE))
lib/Makefile:pbl-$(CONFIG_PBL_CONSOLE) += vsprintf.o
pbl/Makefile:pbl-$(CONFIG_PBL_CONSOLE) += console.o
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:

barebox binary that can be linked to. Although the whole imd infrastructure
will be removed by the linker later in the build process as soon as it
figures out that nothing inside barebox is using it, we still have to
provide a dummy function to keep the build going.
