The SPL image for the rk3288 boards has to fit into 32 KiB. This includes
4 KiB for the device tree and up to 2 KiB for the file header.
I'm not related to this board (and don't mean to step against this
patch), but I have similar problems on socfpga (though with 64 KiB, not
32 KiB) and trying to solve them, so:
How do you know the DTB is 4 KiB maximum? Is there a check for this?
Aside from that, I don't know how it is for rk3288, but socfpga
allocates initial stack, heap and 'gd' into the same RAM, so available
size check should also substract that from my 64 KiB. How is this
handled here?

Without the patch we missed to see that the TinkerBoard
spl/u-boot-spl-dtb.bin file is too big.
