Creating static volumes in barebox already works,

Fixes: bc94fb3 bootm: Initialize bootm_data defaults in single place
bootm_data_init_defaults() must be called before filling in the values
from the commandline options, otherwise the values will be overwritten
in bootm_data_init_defaults().

Now that the bootm code can be used without the command, we have to
move the magicvar descriptions from the command code to the common
bootm code aswell.

bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.

nvvar support not only needs globalvar, but also persistent
environment storage. Add a separate default-y option which
depends on ENV_HANDLING for this case. Make the option visible
to let the user decide whether he wants to have this option
and add a help text to make this decision easier.

ENV_HANDLING is usable even without explicit loadenv/saveenv command
support. Instead of selecting this option from loadenv/saveenv, make
this option visible. loadenv/saveenv can then depend on ENV_HANDLING
rather than selecting it. This reduces Kconfig dependencies hassles.

Currently global environment variables are only enabled when the
"global" command is enabled. In fact, they could be used even with
the "global" command disabled, so make the GLOBALVAR option visible.

We have defined stdin, stdout and stderr as integer file descriptors,
but normally they should be FILE *. Also fprintf, fputc and fputs take
file descriptors instead of FILE *. As FILE * are inconvenient in the
barebox environment replace the f* functions with the corresponding d*
functions. dprintf is POSIX conform whereas dputc and dputs are barebox
specific, but do not conflict with any stdc function. fgetc is unused
and can be removed without replacing it.

Our asprintf and vasprintf have different prototypes than the glibc
functions. This causes trouble when we want to share barebox code
with userspace code. Change the prototypes for (v)asprintf to match
the glibc prototypes. Since the current (v)asprintf are convenient
to use change the existing functions to b(v)asprintf.

It becomes a common case that the Kernel is loaded from the filesystem
which later becomes the rootfs. This adds a possibility to let bootm
automatically append the root= option to the kernel command line. This
is done when global.bootm.appendroot is true.

fixes: 81737c1 mtd: Fix erasing of devices >4GiB
Several places erased a complete flash partition passing ~0 as count to
erase(). With the above commit count to erase was changed from an unsigned
type to a signed type, so the (count > f->size - offset) check in
erase() no longer triggers and the ~0 count is no longer adjusted to the whole
device size. Among other things this results in saveenv failures on NOR
flashes.
This patch fixes this by introducing an explicit macro for erasing the
whole device which is tested for in erase(). All other negative values
are rejected.

This patch fixes the wrong range of i2c addresses used by the i2c_probe
command when a stop address is provided. In this case the start address
(startaddr) was taking the value of the stop address and the stop address
(stopaddr) was always set to its default value.

This was an open fixme for some time. ubiformat does not care about used
ubi volumes or attached ubis.
This patch adds functionality that umounts all filesystems that are
mounted from this nand device. After that the ubi is detached. Then the
normal ubiformat code reformats the ubi. If a ubi was detached
previously, the code tries to reattach the ubi. Filesystems are not
remounted.

We want to extend the functionality of the ubi detach function,
but we don't want to change the original detach function to make
UBI updates easier. This adds a barebox specific detach function
which encapsulates the original UBI function. Also this makes the
original ubi detach function internal to ubi.

Some SoCs allow to store multiple boot images on a device in order to
improve robustness. This adds a -r option to barebox_update to indicate
we do not want to make an update but instead repair/refresh an existing
image. Handlers which want to support this feature must set the
BBU_HANDLER_CAN_REFRESH flag during registration.

This adds a command to flip bits in a Nand flash. This is useful for
testing purposes to check if flipped bits are corrected and if the
driver returns the correct number of bitflips.
The command writes a configurable number of bitflips to a single Nand
page. If the -r option is not given the results are reproducible, so
calling the same command twice will revert the bitflips.
The command uses the raw read/write Nand operations which are probably
less tested than the regular read/write operations, so the command may
produce surprising results.
As of writing the command has been tested with the GPMI Nand driver and
the imx-nand driver with fixes posted.
