commit 6285efb8a118940877522c4c07bd7c64569b4f5f upstream.
the twin-die combined memory device should be treatened as X8
device and not as X16 one

Reviewed-by: Kostya Porotchkin <kostap@marvell.com>
[ - the default value for twin_die_combined is set to NOT_COMBINED for
all boards, as this was default behaviour prior this change ]

Update from original Marvell U-Boot to mainline U-Boot:
-------------------------------------------------------
Generate the U-Boot image with these commands:
$ make clearfog_defconfig
$ make
The resulting image including the SPL binary with the
full DDR setup is "u-boot-spl.kwb".
Now all you need to do is copy this image on a SD card.
For example with this command:
$ sudo dd if=u-boot-spl.kwb of=/dev/sdX bs=512 seek=1
Please use the correct device node for your setup instead
of "/dev/sdX" here!
Install U-Boot on eMMC:
-----------------------
To make SPL load the main U-Boot image from the eMMC boot partition enable
eMMC boot acknowledgement and boot partition with the following U-Boot
command:
mmc partconf 0 1 1 0
Install U-Boot on eMMC boot partition from Linux running on Clearfog:
echo 0 > /sys/block/mmcblk0boot0/force_ro
dd if=u-boot-spl.kwb of=/dev/mmcblk0boot0
Note that the SD card is not accessible when the Clearfog SOM has eMMC.
Consider initial boot from UART (see below).
Install U-Boot on SATA:
-----------------------
When loading the main U-Boot image from raw SATA sector, set
CONFIG_SPL_SATA_RAW_U_BOOT_SECTOR to 0x141.
Boot selection:
---------------
Before powering up the board, boot selection should be done via the SW1 dip
switch (0: OFF, 1: ON):
- SPI: 00010
- SD/eMMC: 00111
- M.2 SSD: 11100
- UART: 01001 [1]
[1]: According to SolidRun's manual, 11110 should be used for UART booting on
the ClearFog 'Pro' variant.
However, this doesn't work (anymore) at least on Rev. 2.1 (but '01001' as
mentionend for the 'Base' variant does).
Boot from UART:
---------------
Connect the on-board micro-USB (CF Pro: CON11, CF Base: CON5)
to your host.
Set the SW1 DIP switches to UART boot (see above).
Run the following command to initiate U-Boot download:
./tools/kwboot -b u-boot-spl.kwb /dev/ttyUSBX
Use the correct UART device node for /dev/ttyUSBX.
When download finishes start your favorite terminal emulator
on /dev/ttyUSBX.
