2017-06-14ubi-utils: Return error code if command line option is unknownDaniel Wagner
The tools in question will quit with an exit code 0 if the command line option was not recognized. By returning an error code a calling script has the possibility to distinguish between a real success and an invalid invocation. We need to return -1 instead of EXIT_FAILURE to be consistent with the other exit code places.

2014-03-25ubi-utils: Add ubiblock toolEzequiel Garcia
With the addition of block device access to UBI volumes, we now add a simple userspace tool to access the new ioctls. Usage of this tool is as simple as it gets: $ ubiblock --create /dev/ubi0_0 will create a new block device /dev/ubiblock0_0, and $ ubiblock --remove /dev/ubi0_0 will remove the device. Artem: slightly changed the header comment. Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>
