ubifs filesystem image: line up and improve Config.in options
Triggered by the 'some comment required here', this patch updates the Config.in comments for the ubifs filesystem image options. This includes: - 'erase block' --> 'eraseblock' (following mtd online documentation) - remove 'UBI' prefix to make options uniform. Sometimes the option is not a property of UBI but rather of the flash. Also, line up the name of the option with the help of mkfs.ubifs. - add help text on all options, referring to the mkfs.ubifs/ubinize options Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Acked-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
