[PATCH v3 0/9] ARM: berlin: add nand support

[antoine.tenart@free-electrons.com (Antoine Tenart)]

Hi all,

This series introduces the support for the Marvell Berlin nand
controller. It is based on top of v4.0-rc1 and was tested on the
Marvell Berlin BG2Q DMP board.

The support is added into the existing pxa3xx nand controller. Some
additions were done in order to get this controller working:
- Support for a non mandatory ECC clock has been added.
- The Berlin nand controller needs to poll the status register.
- Sequences of commands are quite different in order to perform write
  operation.

Thanks!

Antoine

        - Ensured commit 4/10 was useless and removed it
        - Fixed typos, cosmetic
