This makes not much sense to me. If what you claim is true, than JFFS2 in U-Boot 
and Linux would be incompatible for all MTD drivers. This would also mean that 
JFFS2 in Linux 3.7 is incompatible with Linux-next (since 3.7 was the last sync 
point between U-Boot and Linux MTD). Is that really the case?

Best regards,
Marek Vasut
