I have to run the unlock command manually before mounting jffs2. Something
like "unlock /dev/mtd0". Kernel needs to have the MTD character device
configured and the corresponding chip driver needs to have lock/unlock
functions implemented. Whether sectors are locked after power on depends
on the chip. The reverse works also: "lock /dev/mtd0 0 -1" would lock all
sectors.
