Turn on the ATAPI DMADIR support if word 62 indicates it. Signed-off-by: Albert Lee <albertcc@xxxxxxxxxx> --- (Revised to add mwdma/udma mask of word 62 per Jeff's comments. Need more testing once I get the SiI 3811, etc.) ATAPI DMADIR follow-up patch to turn on the DMADIR support automatically by checking identify device word 62. (Thanks for Jeff and Tejun's pointer.) According to Jonathan's test result, SiI 3611 (the current known bridge that requires the ATAPI DMADIR support) doesn't implement word 62. So, the atapi_dmadir parameter is preserved to enable the DMA DIR support manually as work around. Patch against upstream (c2a6585296009379e0f4eff39cdcb108b457ebf2). For your review, thanks.
I ACK the patch, though like I said, I would like to see this tested first with some compliant devices.
