[RFC PATCH 0/9] mtd: nand: add sunxi NAND Flash Controller support

[Boris BREZILLON]

Hello,

This series add the sunxi NFC support with 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:
 - HW ECC support
 - DMA support
 - HW randomization support
 - many more 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
