Summary

0001105: Missing mkfs.jffs2 option for NAND Flash

Description

When generating a JFFS2 rootfs for a NAND flash, an option should be added to mkfs.jffs2 otherwise Linux kernel is printing a lot of warning messages (during rootfs mounting) like:
CLEANMARKER node found at 0x00...... has totlen 0xc != normal 0x0

These messages are considerably slowing down system boot.

"-n" option should be added to JFFS2_OPTS variable in target/jffs2/jffs2root.mk Makefile.

Additional Information

I suggest to add a "Put cleanmarkers" option to JFFS2 Config.in and add the "-n" option to JFFS2_OPTS if user want it.
I'm not sure to have fully understood yet if these cleanmarkers are really used on NAND Flash:
