mtd-utils: flash_erase: Add an option for JFFS2 cleanmarker size
JFFS2 supports buffer mode for ECC'd NOR Flash that cleanmarker size is rounded up to mtd->writesize, while the '-j' option in flash_erase utility uses fixed 12 bytes. That makes flash program ops unaligned to mtd->writesize and causes program error or disables ECC. The mkfs.jffs2 utility supports '-c' option that allows users to specify cleanmarker size. This patch implements '-c' option in the flash_erase that can be used along with '-j' option.
