90bcc3d38d driver/ddr: Add support for setting timing in hws_topology_map
The DDR3 training code for Marvell A38X currently computes 1t timing
when given board topology map of the Turris Omnia, but Omnia needs 2t.

This patch adds support for enforcing the 2t timing in struct
hws_topology_map, through a new enum hws_timing, which can assume
following values:
  HWS_TIM_DEFAULT - default behaviour, compute whether to enable 2t
                    from the number of CSs
  HWS_TIM_1T      - enforce 1t
  HWS_TIM_2T      - enforce 2t

This patch also sets all the board topology maps (db-88f6820-amc,
db-88f6820-gp, controlcenterdc and clearfog) to have timing set to
HWS_TIM_DEFAULT.

d08957e6ba arm: mvebu: db-88f6820: Drop obsolete binary.0 placeholder
It has been superseded in kwbimage.cfg in favor of an SPL in commit
9e30b31d20 (arm: mvebu: db-88f6820: Add
SPL support with DDR init code). Found via code review.

b322c83aa4 arm: mvebu: Consolidate board Kconfig options into one file
Merging all the board specific Kconfig options into the main Kconfig file
for mach-mvebu makes things easier to maintain.

6451223a8d arm: mvebu: Add DM and OF_CONTROL support to SPL
This patch adds full DM support to the SPL on MVEBU. Currently
only serial is supported. Other drivers will follow.

This patch also adds the necessary config values for the DEBUG UART
to the MVEBU defconfig files. This came in handy while implementing
this DM support.

Additionally, the mvebu specific SPL linker script is removed and
this common one is used instead:

   arch/arm/cpu/u-boot-spl.lds

This common linker script already handles all special cases. No need
to reinvent the wheel for MVEBU here.

490753ace3 arm: mvebu: a38x: serdes specification cleanup
Instead of allocating space in the driver for the serdes
specification table, just allow the board file to set a pointer
to it.  Also, allow the board to only specify the lanes that are
used instead of including unused lanes.

544acb07ec arm: mvebu: a38x: Remove unsupported topologies
A lot of extra configuration information was left over in the
Marvell serdes and DDR3 initialization code for boards that
U-boot does not support.  Remove this extra config information,
and the concept of fixing up board topologies with information
loaded from an EEPROM.  If this needs to be done, it should be
handled in the board file, not in core code.

2a0b7dc3b6 arm: mvebu: Enable NAND controller on MVEBU SoC's
This patch enables the NAND controller on the Armada XP/38x and provides
a new function that returns the NAND controller input clock. This
function will be used by the MVEBU NAND driver.

As part of this patch, the multiple BIT macro definitions are moved
to a common place in soc.h.

9e30b31d20 arm: mvebu: db-88f6820: Add SPL support with DDR init code
This patch adds SPL support for the Marvell DB-88F6820-GP board.
With this change, the bin_hdr from the original Marvell U-boot
is not needed any more on this board. The sources from bin_hdr
(SERDES/PHY and DDR setup) are now integrated in mainline
U-Boot. And this patch enables them for this board.

2bae75a488 arm: mvebu: Add Armada A38x DB-88F6820-GP board support
This patch adds support for the Marvell DB-88F6820-GP Armada A38x
evaluation board.

Supported peripherals are:
- UART
- Ethernet (mvneta)
- I2C
- SPI (including SPI NOR flash)

Please note that this board support right now only supports the
main U-Boot. Without the bin_hdr integration (DDR training etc). This
will be added in a few days / weeks to complete this board port. But
till then this U-Boot version can be run on the target via the
original Marvell U-Boot via this command:

tftpboot 4000000 db-88f6820-gp/u-boot.bin;go 4000000
