From be3cb3d84bb8dffecb7c5570355866075caa7e95 Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Fri, 21 Mar 2008 22:25:43 +0100 Subject: [SCSI] WD33C93: let platform stub override no_sync/fast/dma_mode SGI machines with WD33C93 allow usage of burst mode DMA, which increases performance noticable. To make this selectable by the sgiwd93 stub, setting the values for no_sync, fast and dma_mode has been moved to the individual platform stubs.
