Sven Schnelle 9e58f17270 fdc/i8257: implement verify transfer mode ... While working on the Tulip driver i tried to write some Teledisk images to a floppy image which didn't work. Turned out that Teledisk checks the written data by issuing a READ command to the FDC but running the DMA controller in VERIFY mode. As we ignored the DMA request in that case, the DMA transfer never finished, and Teledisk reported an error. The i8257 spec says about verify transfers: 3) DMA verify, which does not actually involve the transfer of data. When an 8257 channel is in the DMA verify mode, it will respond the same as described for transfer operations, except that no memory or I/O read/write control signals will be generated. Hervé proposed to remove all the dma_mode_ok stuff from fdc to have a more clear boundary between DMA and FDC, so this patch also does that.
