------------------------------------------------------
Subject: libata-sff: unbreak non DMA capable controllers again
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
Seems nobody else is checking/testing this case as it keeps getting horked.
If we have no BAR4 mapping on an SFF controller this is *NOT* an error, it
just means it isn't doing BMDMA.
