board=WNDR4300 18.06.x
block info
The total capacity of NAND FLASH is 128M but this partition occupies 96M and is not used. So why is there this reserved partition, and what does its existence do?
The capacity of the partition /dev/ubi0_1 /overlay that the system can really use now is too small and only 14M, so can /dev/mtdblock11 be used to extend /overlay, or can it be merged with the current /overlay partition?
Has the official firmware of OpenWRT-21.02.0 updated the partition so that the 128M partition can now be used?

Will the following configuration take effect after the system restarts?
config mount
option target '/overlay'
option device '/dev/mtdblock11'
option fstype 'jffs2'
option enabled '1'

I also think so, OpenWRT should use the original firmware partition! But this is such a waste of space.

I also saw that the introduction said that the 20.02 version modified the partition, so that the 128M space can be fully used.
