From 02ca5083f60521d09f13224596564a405108bc4c Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Fri, 19 Mar 2010 04:46:47 +0000 Subject: dmaengine: shdma: Common SH_DMA_SLAVE_NUMBER Move SHDMA_SLAVE_NUMBER from asm/dmaengine.h to shdma.h. Set it to 256 to support a wide range of processors. The amount of memory consumed by this change is limited to 256 bits. While at it, rename to SH_DMA_SLAVE_NUMBER to match with the rest of the file.
