[Yaffs] Yaffs2 and MLC NAND with Block size 256K

Hi,

I'm using a year old snapshot of Yaffs2 cvs tree. I want to know if
there are any assumptions about the block size for 2K page NAND. For
example, Samsung K9F4G08U0A is SLC NAND with 2K page size and 128K
block size. Samsung K9G4G08U0A is MLC NAND with 2K page size and 256K
block size (both have same device id - 0xDC)

So, are there any assumptions about block size for 2K page ? or 256K
block size will work as is..

>From README-linux: "Block - Eraseable unit. 64 Pages. (128K on 2K
NAND, 32K on 512b NAND)"

Thanks
Amol
