this is probably not the issue. the xhci works fine with the 1gb and 2gb
variants. and the issue they had was that they missed flushing the
dcache for the scratchpad memory they hand to the xhci controller.
we do flush the dcache for these regions here:
dmaflush(1, ctlr->sbp, ctlr->nscratch*ctlr->pagesize);
dmaflush(1, ctlr->sba, ctlr->nscratch*8);
