I think i've made the comment elsewhere but:
1) is there source available for the ROM code?
2) why are we calling it rather than our own SHA512 code?
3) why would we not verify the ROM code result against a local SHA512
   implementation?

Are future processors going to follow this model? If not, then let's
just bring in the SHA512 code now and be done with it rather than carry
both?
