From ff3d4578840fd96a50558edf02ca0178b9ebb652 Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Sun, 3 Jan 2016 16:05:25 +1100 Subject: ncr5380: Implement NCR5380_dma_xfer_len and remove LIMIT_TRANSFERSIZE macro Follow the example of the atari_NCR5380.c core driver and adopt the NCR5380_dma_xfer_len() hook. Implement NCR5380_dma_xfer_len() for dtc.c and g_NCR5380.c to take care of the limitations of these cards. Keep the default for drivers using PSEUDO_DMA. Eliminate the unused macro LIMIT_TRANSFERSIZE. Signed-off-by: Finn Thain Reviewed-by: Hannes Reinecke Tested-by: Ondrej Zary Tested-by: Michael Schmitz Signed-off-by: Martin K.
