In fact, the code to do this should still be floating around
git.xilinx.com, although someone would likely have to bring it up to the
current kernel versions.
My intention was to treat it as two independent configuration options:

1) .dtb location is in BRAM
2) .dtb is passed compressed (regardless of location)
