By "this" you mean the CHRP standard? At least in Linux the "CHRP" platform has always been 32-bit only AFAIK. My memory is that JS20/JS21 used the "maple" platform, which was a 64-bit only bare-metal platform, possibly it was actually == CHRP, but we didn't call it that in Linux. But maybe I'm wrong, you were more involved than me back than, and it was a long time ago :) cheers
