Hi Artem

OneNAND can support for full block read also in sync burst 
block read mode ,so why u want to limit bulk read only for 4 
pages , with sync burst enable u can read max 64 pages.
so in place of max 4 pages , u can set max to 64 it will be 
improve performance if sync burst mode is upported.

Actually UBIFS reads up to whole eraseblock. So if you have
a file, and it is resided in consecutive NAND pages of an
eraseblock, and UBIFS has decided to do read-ahead, it would
read whole eraseblock. So for OneNAND, indeed UBIFS may read
up to 64 NAND pages at one go.
