Konstantin Porotchkin 1e179c7946 plat/marvell: fix SPD handling in dram port
The DRAM port code issues a dummy write to SPD page-0 i2c address
in order to select this page for the forthcoming read transaction.
If the write buffer length supplied to i2c_write is not zero, this
call is translated to 2 bus transations:

- set the target offset
- write the data to the target

However no actual data should be transferred to SPD page-0 in order
to select it. Actually, the second transation never receives an ACK
from the target device, which caused the following error report:

ERROR:   Status 30 in write transaction

This patch sets the buffer length in page-0 select writes to zero,
leading to bypass the data transfer to the target device.
Issuing the target offset command to SPD page-0 address effectively
selects this page for the read operation.

Moti Buskila 4827068989 plat: marvell: armada: add support for twin-die combined memory device
the twin-die combined memory device should be treated as
X8 device and not as X16 one. This patch is required to
re-enable compilation after BLE (mv-ddr-marvell) firmware upgrade.

Luka Kovacic 70ec0d72b6 plat: marvell: armada: a8k: Add support for iEi Puzzle-M801 board
Add support for the iEi Puzzle-M801 board that is based on
the Marvell Armada 88F8040 SoC.

It supports 1 x 288-pin DIMM, DDR4 2400MHz up to 16 GB (ECC).

The iEi Puzzle-M801 board is using a custom MCU to handle board
power management. The MCU is managing the boards power LEDs, fans
and some other periferals. It's using UART for communication.
