You could reduce indentation by having this be:
if (wlc_hw->sih->boardvendor != PCI_VENDOR_ID_BROADCOM)
return true;

and remove the goodboard variable by having this return false immediately.

You could also drop the else and have this as
if (boardrev <= 0xff)
return true;

then just return true here.
