--------------------------------------------------------------------------
I think just simply named mtd 11 (96MB) as ubi should could work.
In boot process , it find mtd nameed ubi and attach as ubi0 and create
block device interface from ubi0_0 as root(rom) path. mount ubi0_1 as
/overlay.
Both just been affected by the mtd name not affeted by mtd num and
offset address
