2016-04-19mtd: create an mtd_ooblayout_ops struct to ease ECC layout definitionBoris Brezillon
ECC layout definitions are currently exposed using the nand_ecclayout struct which embeds oobfree and eccpos arrays with predefined size. This approach was acceptable when NAND chips were providing relatively small OOB regions, but MLC and TLC now provide OOB regions of several hundreds of bytes, which implies a non negligible overhead for everybody even those who only need to support legacy NANDs. Create an mtd_ooblayout_ops interface providing the same functionality (expose the ECC and oobfree layout) without the need for this huge structure. The mtd->ecclayout is now deprecated and should be replaced by the equivalent mtd_ooblayout_ops. In the meantime we provide a wrapper around the ->ecclayout field to ease migration to this new model.

2016-04-19mtd: nand: sunxi: move some ECC related operations to their own functionsBoris Brezillon

2016-04-19mtd: nand: sunxi: poll for events instead of using interruptsBoris Brezillon
Some NAND operations are so fast that it doesn't make any sense to use interrupt based waits (the scheduling overhead is not worth it). Rename sunxi_nfc_wait_int() into sunxi_nfc_wait_events() and add a parameter to specify whether polling should be used or not. Note that all sunxi_nfc_wait_int() are moved to the polling approach now, but this should change as soon as we have more information about the approximate time we are about to wait (can be extracted from the NAND timings, and the type of operation).
