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. Signed-off-by: Simon Glass <>
