Subject: [RFC PATCH v2 00/14] mtd: nand: add sunxi NAND Flash Controller support
Date: Wed, 29 Jan 2014 15:34:10 +0100 [thread overview]
Message-ID: <1391006064-28890-1-git-send-email-b.brezillon.dev@gmail.com> (raw)
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
