mtd-utils: support 4096+64 page sizes
Add support for oobsize 64 and writesize 4096 in nanddump & nandwrite. Artem: some more info from further e-mail exchange: > Are there flashes with the 4096 page / 64 spare combination? Could you > refer to one? May be any URL? I thought 4096 comes with 128. Much to my regret I can't provide a URL because is not public. IGEP v2 board has a Onenand with two dice of 2048/64 spare combination but mtd views 4096/64. The minimal write page is 4K (2K from first dice and 2K from second dice).
