u-boot/board/sunxi/board.c
Andre Przywara 54254ba78a sunxi: use SPL header DT name for FIT board matching 
Now that we can store a DT name in the SPL header, use this string (if
available) when finding the right DT blob to load for U-Boot proper.
This allows a generic U-Boot (proper) image to be combined with a bunch
of supported DTs, with just the SPL (possibly only that string) to be
different.
Eventually this string can be written after the build process by some
firmware update tool.
