[PATCH 0/4] mtd: nand: Add support for Evatronix NANDFLASH-CTRL

[Boris Brezillon]

Hi Ricard,

I was not in Cc of this series, so you're either developing an old
kernel version, or you didn't check the MAINTAINERS file (or didn't run
get_maintainer.pl on your series). And please, next time make sure
patches 1 to X are sent in replies to your cover letter.

I'll to review the driver soon.
