[PATCH 0/3] mtd: nand: sunxi: fix SLC NAND support

Hello,

Those 3 patches aims a fixing support for SLC NANDs with rather small
NAND pages (<= 4k).

The first patch promote 512 bytes ECC steps to 1k steps, which should
both save a few OOB bytes and provide stronger ECC.
The second patch checks the ECC step value, and rejects any NAND that
requires ECC steps != 512 | 1024.
The last patch implements ecc->write_subpage(), thus fixing a NULL
pointer dereference when the NAND chip supports subpage write.

Best Regards,

Boris
