One of the reasons why I didn't even consider jffs2 for IMX6 is that the IMX6 NAND controller with hardware ECC support uses the entire OOB area which was needed by jffs2. Their might be support in jffs2 now for not using OOB data but ubi/ubifs does seem to be the popular choice these days for NAND based filesystems.
