fix erasing/protecting flashes with unspecified size ...

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.

i2c_probe: fix wrong start and stop addresses ...

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.

bbu: Allow to refresh/repair images ...

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.

ubiformat: Cleanly umount and detach the ubi before formating ...

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,

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.

commands: Create nand_bitflip command ...

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.

bootm: add initial FIT support ...

This implementation is inspired by U-Boot's FIT support. Instead of
using libfdt (which does not exist in barebox), configuration signatures
are verified by using a simplified DT parser based on barebox's own
code.

Currently, only signed configurations with hashed images are supported,
as the other variants are less useful for verified boot. Compatible FIT
images can be created using U-Boot's mkimage tool.
