UBI-utils: add compare feature
This is a new feature for pfiflash, called "--compare". It allows the user to simulate a pfiflash session without actually changing the flash content. If the flash content is equal to the data in the pfif file, pfiflash returns zero. A positive value is returned when the flash content differs from the pfi file, which indicates that an update is necessary. This feature is useful when a controller mounts an NFS share during boot and has to determine if a pfi file stored on this share contains a code update. Modified PDD values are also registered by the compare feature. Signed-off-by: Alexander Schmidt <alexs@linux.vnet.ibm.com>
