Baruch Siach ca1a4c8632 mvebu: select boot device at SoC level
Move the gdsys Controlcenter DC specific build time kwbimage.cfg
generation code into the mach-mvebu/ directory to be shared by all 32bit
mvebu platforms.

Remove board specific kwbimage.cfg files, and use the generated one
instead. These files are all identical, with two exceptions. Clearfog
and Helios4 use the sdio boot device, whereas all others use spi. Update
the defconfigs for the exceptional boards to generate the same
kwbimage.cfg as before.

Update from original Marvell U-Boot to mainline U-Boot:
-------------------------------------------------------

Generate the U-Boot image with these commands:

$ make helios4_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!

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
 - SATA1:   11100
 - UART:    11110

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 -p -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.
