If SPL_OF_CONTROL is being added, why do you need to manually add the stuff above for the serial port? Checkout the da850-evm-u-boot.dtsi file. I adds the device tree entries for the serial port to appear in the SPL DTB.
See http://git.denx.de/?p=u-boot.git;a=commit;h=f7c1d53605d9ec528abacda9ba1763c6...
I tried to follow the example from this patch but for some reason adding u-boot,dm-spl; to the soc@1c00000 node in da850-lcdk-u-boot.dtsi results in the final image being reported as corrupted by the aisimage tool:
[...] COPY spl/u-boot-spl.dtb CC spl/common/spl/spl.o LD spl/common/spl/built-in.o CC spl/lib/display_options.o LD spl/lib/built-in.o LD spl/u-boot-spl OBJCOPY spl/u-boot-spl-nodtb.bin CAT spl/u-boot-spl-dtb.bin COPY spl/u-boot-spl.bin MKIMAGE spl/u-boot-spl.ais Error: - AIS Image corrupted CAT u-boot.ais CFGCHK u-boot.cfg
The image doen't boot (or at least there's nothing on the console).
I'm not sure what's causing it. Any idea?
