If my addled brain is in the right fluids, I seem to recall Broadcom got into a bit of a flap because the patches to deal with the 47xx didn't get pushed right back to GCC. So multiple version(s) of the patches exist. Other than that, I believe the backplane stuff in the SoCs are similar, but NOT identical -- I think the bcm47xx memory controller needs a bit of a kick up the arse to work, whereas the bcm5365 based stuff is generally setup by firmware. I think I posted something to list(s) about this in the last 2-3 years.... later BMS
