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.

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.
While at it, add a help text for this option.

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.

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

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

BBU_HANDLER_CAN_REFRESH flag during registration.

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

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.
