[PATCH v1 0/4] mtd: nand: omap: add support for BCH16_ECC

This patch series add support of BCH16_ECC scheme.
As BCH16_ECC scheme generates 26bytes of ECC syndrome per 512B data,
hence this scheme is usable only for NAND devices having 4K or above
page-size, as their OOB/spare area has enough space to accomodate ECC.

This patch series is applicable over an above following series:
[1] [Patch] mtd:nand:omap2: clean-up of supported ECC schemes 
 http://lists.infradead.org/pipermail/linux-mtd/2013-July/047530.html
[2] [Patch] optimize and clean-up of OMAP NAND and ELM driver
 http://lists.infradead.org/pipermail/linux-mtd/2013-July/047538.html

Also this BCH16_ECC patch series is sparsely tested, due to limited
availability of boards with 4K/224NAND, so request the users to test
the mentioned series, and provide Tested-by.
