I know this is just a small nitpick, but can you re-submit this
with a subject similar to the other commits:

""mtd: nand: pxa3xx: Add support for 2048 bytes page size devices""

Also, I think you can add some details about the patch in the change
log. Something along these lines might be fine:

""
This commit adds support for devices with 2048B page sizes and
4-bit ECC strength requirements. This is achieved by enabling the BCH
ECC engine, which provides a higher strength: 16-bit over 2048 bytes.

Additionally, add a proper ECC layout to model the controller's view
of the device (where 'U' means unused and 'B' is the bad block marker):

 ----------------------------------------------------
 | 2048B data | B | B | 30B spare | 30B ECC | U | U |
 ----------------------------------------------------
""

With these modifications you can also add:

Thanks a lot for the contribution!
