From: Sneha Narnakaje <[email protected]> This patch adds support for NAND devices with 4K page size and 128bytes of OOB. In the patch, the macros for max page and oob sizes are updated. The nand_ecclayout data structure is also updated accordingly. Note that The same macros will have to be modified if the support has to be extended up to 8K page size.
