Look at this piece of code in boot/image-fit.c :

2489                 debug("%s loaded at 0x%08lx len=0x%08lx\n",
2490                                 uname, ovload, ovlen);
2491                 ov = map_sysmem(ovload, ovlen);
2492
2493                 ovcopylen = ALIGN(fdt_totalsize(ov), SZ_4K);
2494                 ovcopy = memalign(8, ovcopylen);
2495                 if (!ovcopy) {
2496                         printf("failed to duplicate DTO before 
application\n");
2497                         fdt_noffset = -ENOMEM;
2498                         goto out;
2499                 }
2500
2501                 err = fdt_open_into(ov, ovcopy, ovcopylen);
2502                 if (err < 0) {
2503                         printf("failed on fdt_open_into for DTO\n");

This is where it fails. Is $ov or $ovcopy 4-byte aligned ? Enable the 
debug() print at the beginning (or #define DEBUG at the beginning of 
this file) to find out.

If $ov is 4-byte aligned, try to generate your fitImage with "mkimage 
... -E -B 8 ..." , does that make any difference ?
