From 2fb3ec5c9503ba8874e24170de2b40e8f1a58370 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 11 May 2011 16:06:29 +0100 Subject: ARM: Replace platform definition of ISA_DMA_THRESHOLD/MAX_DMA_ADDRESS The values of ISA_DMA_THRESHOLD and MAX_DMA_ADDRESS are related; one is the physical/bus address, the other is the virtual address. Both need to be kept in step, so rather than having platforms define both, allow them to define a single macro which sets both of these macros appropraitely.
