Don't you mean this?

 ./firefly/tools/mkimage -T rkimage -d ./firefly/spl/u-boot-dtb.spl.bin

You need to send U-Boot and its device tree. Perhaps there is a
mistake in my instructions but this is what I see here:

http://patchwork.ozlabs.org/patch/487875/

+To create a suitable image and write it to the board:
+
+   ./firefly-rk3288/tools/mkimage -T rkimage -d
./firefly-rk3288/spl/u-boot-spl-dtb.bin out
+   cat out | openssl rc4 -K 7c4e0304550509072d2c7b38170d1711 | rkflashtool l
+

This needs to be <32KB or it will not boot. It seems to be a Rockchip
boot ROM limitation.

With my toolchain it is. I'll check it again later on. I do have a
patched toolchain which doesn't add a whole load of unused strings.
Maybe that is the difference. Probably I need to cut the size down a
bit.
