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.
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.
The Samsung K9LBG08UXD parts are 32Gbytes x 8 bits 3.3V parts with the 0xD7 identifier. Add these to the list of known devices IDs.
