Rebased version for this nand chip has one problem in detecting its page size using in nand_base.c. If we set page size 0 in nand_ids.c, we would get the calculation result as page size 2048, while the true page size is 4096.
Is the ID data bad, or is there a bug in nand_get_flash_type(), or is it some new ID format that needs support?
I think it is reasonable to set the 32Gigabit nand as 4k page by default, as all nand been product in this size has more than 4k page.
"more than"? Are there larger page size NANDs out there?
And if so, wouldn't hard-coding the page size at 4096 bytes be a problem?
Is there zero possibility that a 2k page NAND in this size could be made in the future (e.g. for compatibility with controllers that don't support 4k pages)?
