The example FIT image source files do not compile with the latest dtc and mkimage. The following error message is produced:
DTC: dts->dtb on file "kernel.its" Error: kernel.its 7:0 - 1:0 syntax error FATAL ERROR: Unable to parse input tree ./mkimage: Can't read kernel.itb.tmp: Invalid argument
The FIT image source files are missing the "/dts-v1/;" directive at the beginning of the file. Add the directive to the examples.

Note that to make U-Boot's mkimage utility do anything at all, I had to manually apply Remy's patch from Oct. 28 as well. The patch is titled: [PATCH] Building of FIT images does not work.
After applying the above patch, then dtc errored with the message reproduced above in the commit text.
