From e24cca19babe33a7d05712df041f5abbeca4f1bf Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sat, 19 May 2012 18:50:09 +0900 Subject: sh: Kill off MAX_DMA_ADDRESS leftovers. We don't support the ISA DMA API, so this is only ever misused. The dma-sh case inadvertently broke the dreamcast case by testing the wrong variable for the total number of channels, so this fixes that up too.
