4444d230ac mvebu: axp: Rename MV_DDR_32BIT to CONFIG_DDR_32BIT
This should make it clear that this symbol is meant to be defined by
board headers.

698ffab239 arm: mvebu: Make ECC support configurable on Armada XP
Currently, ECC support is enabled for all Armada XP boards. So the
DDR3 driver tries to configure the controller with ECC support, even
on boards without ECC. This patch makes this ECC optional which now
can be configured on a board-per-board basis.

a3ed9789e7 arm: mvebu: sdram: Enable ECC support on Armada XP
This is tested on the DB-MV784MP-GP eval board. To really enable ECC
support on this board the I2C EEPROM needs to get changed. As it
saves the enabling of ECC support internally. For this the following
commands can be used to enable ECC support on this board:

Its recommended for first save (print) the value(s) in this EEPROM
address:

=> i2c md 4e 0.1 2
0000: 05 00    ..

To enable ECC support you need to set bit 1 in the 2nd byte:

Marvell>> i2c mw 4e 1.1 02
Marvell>> i2c md 4e 0.1 2
0000: 05 02    ..

To disable ECC support again, please use this command:

Marvell>> i2c mw 4e 1.1 00
Marvell>> i2c md 4e 0.1 2
0000: 05 00    ..

On other AXP boards, simply plugging an ECC DIMM should be enough to
enable ECC support.

ff9112df8b arm: mvebu: drivers/ddr: Move Armada XP DDR init code into new directory
With the upcoming addition of the Armada 38x DDR support, which is not
compatible to the Armada XP DDR init code, we need to introduce a new
directory infrastructure. To support multiple Marvell DDR controller.

This will be the new structure:

     drivers/ddr/marvell/axp
     Supporting Armada XP (AXP) devices (and perhaps Armada 370)

     drivers/ddr/marvell/a38x
     Supporting Armada 38x devices (and perhaps Armada 39x)
