[PATCH v2 0/5] Add device tree support of Atmel NAND driver

[Raphaël Poggi]

Change since v1:
	* Reorder patchs
	* Fix some clean style issue.

This patchset adds the device tree support for the Atmel NAND driver.

The first patch removes the NAND_ATMEL_PMECC config. With this removal
we can manage in a better way the device tree / non device tree probing of the driver, because the plateform data
and device tree share the same structure member and logics.

The second patch adds the has_pmecc on boards which need it.

The third patch retrieves the ecc_mode from the plateform data and remove this code:

        nand_chip->ecc.mode = NAND_ECC_SOFT;

which arbitrary sets the ecc.mode to NAND_ECC_SOFT and changes the value depending of the config and plateform data.
With this, we can use the same logics for device tree and non device tree probing of the driver.

The fourth patch adds the ecc_mode on boards which are missing it (boards which use NAND_ECC_SOFT).

The fifth patch adds the device tree in the atmel_nand driver.

        (1) mtd: nand: remove NAND_ATMEL_PMECC
        (2) board: atmel: initialise the has_pmecc member
        (3) mtd: atmel_nand: retrieve ecc_mode from pdata
        (4) board: atmel: initialise ecc_mode
        (5) mtd: atmel_nand: add support for device tree
