[RFC PATCH v2 00/14] mtd: nand: add sunxi NAND Flash Controller support

From: Boris BREZILLON
Date: Wed Jan 29 2014 - 09:34:40 EST


Hello,

This series adds support for the sunxi NAND Flash Controller (NFC).
This controller supports up to 8 NAND chip connected.

I'm still in the early stages drivers development and some key features are
missing, but it's usable (I tested it on the cubietruck board).

Here's what's missing:
- DMA support
- HW randomization support
- other improvements ?

This series depends on Emilio's patch series implementing mod0 clks
(http://lists.infradead.org/pipermail/linux-arm-kernel/2013-July/185478.html)
+ an other patch not yet posted
(http://git.elopez.com.ar/linux/commits/5b4eb3ac406b9c98965714d40e8dd6da943d1ab0)


Best Regards,

Boris

Changes since v1:
- add HW ECC support
- rework NAND timings retrieval (use ONFI timing mode instead of raw timings)
- add nand-ecc-level property to specify NAND ECC requirements from DT
