From b9c78022b0e65cdca2541be658f0e74138e92ffe Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 29 Nov 2008 10:50:22 +0000 Subject: [ARM] move MAX_DMA_ADDRESS to mach/memory.h Move the definition of MAX_DMA_ADDRESS from mach/dma.h to mach/memory.h, thereby placing it along side its relative, ISA_DMA_THRESHOLD.
