    -Add hcode package to enable compiling hardware
     reference image
    -Modify pnor and sbe makefiles to include a dependency on
     the hcode repository
    -Modify config files so that p9 platfoms use the compiled
     version of the hardware reference image by default
    -Update hostboot-binaries.mk to install the ring images
     to the staging dir
