c409bd015c spl: Setup default value for OF_LIST
OF_LIST can't remain empty that's why setup it up to default DTB.

If it is empty u-boot.img is created without FDT partition:
For example:
  ./tools/mkimage -f auto -A arm -T firmware -C none -O u-boot -a
0x8000000 -e 0 -n "U-Boot 2016.05-rc3 ..." -E -b  -d u-boot-nodtb.bin u-boot.img
Can't set 'timestamp' property for '' node (FDT_ERR_NOSPACE)
FIT description: Firmware image with one or more FDT blobs
Created:         Wed May  4 15:02:52 2016
 Image 0 (firmware@1)
  Description:  U-Boot 2016.05-rc3-00080-gff2e12ae22a8-dirty for zynqmp
board
  Created:      Wed May  4 15:02:52 2016
  Type:         Firmware
  Compression:  uncompressed
  Data Size:    unavailable
  Architecture: ARM
  Load Address: 0x08000000
 Default Configuration: 'conf@1'
 Configuration 0 (conf@1)
  Description:  unavailable
  Kernel:       unavailable

And then image like this doesn't contain description and link to FDT and
can't boot.

cdf172461c spl: Add a way to specify a list of device trees to include
When building a FIT, more than one device tree can be included. The board
can select (at run-time) the one that it wants.

Add a Kconfig option to allow the list of devices trees (supported by the
board) to be specified.

When using SPL_LOAD_FIT, build u-boot.img in FIT format instead of the
legacy image format. Include all the listed device tree files in this FIT.

5f3f7b79db dts: keep clock-names and clocks in SPL DTB if SPL_CLK is enabled
These two properties are necessary for SPL to get clocks from DT.

Note:
For now, only clock look-up by index is supported (clk_get_by_index()
function), so "clock-names" is never parsed in U-Boot.  However, we
may want to support something like clk_get_by_name() in the future,
so let's keep "clock-names" as well as "clocks".

3d3f60cb7a dts: Add a comment about CONFIG_OF_EMBED being for local use
This comment from README.fdt-control did not end up in the Kconfig, which
is what most people will see. Add it with a few tweaks.

dffb86e468 of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROL
As we discussed a couple of times, negative CONFIG options make our
life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
and here is another one.

Now, there are three boards enabling OF_CONTROL on SPL:
 - socfpga_arria5_defconfig
 - socfpga_cyclone5_defconfig
 - socfpga_socrates_defconfig

This commit adds CONFIG_SPL_OF_CONTROL for them and deletes
CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
the logic.

fa78e0a371 dm: Reduce SPL device tree size
The SPL device tree size must be minimised to save memory. Only include
properties that are needed by SPL - this is determined by the presence
of the "u-boot,dm-pre-reloc" property. Also remove a predefined list of
unused properties from the nodes that remain.

2860f03b91 fdt: Add an option to disable device tree in SPL
Some boards cannot support device tree due to lack of memory. Add an option
to allow these boards to continue to work (and even use driver model).
This is a 'negative' option since most boards are expected to support device
tree in SPL.

783e6a72b8 kconfig: move CONFIG_OF_* to Kconfig
This commit moves:
  CONFIG_OF_CONTROL
  CONFIG_OF_SEPARATE
  CONFIG_OF_EMBED
  CONFIG_OF_HOSTFILE

Because these options are currently not supported for SPL,
the "Device Tree Control" menu does not appear in the SPL
configuration.

Note:
zynq-common.h should be adjusted so as not to change the
default value of CONFIG_SPL_FAT_LOAD_PAYLOAD_NAME.
