From 364230b9952143eb2062dc071e919fb751540ae8 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 1 Aug 2013 15:29:29 -0500 Subject: ARM: use phys_addr_t for DMA zone sizes In order to specify a DMA zone size of 4GB on LPAE systems, the sizes need to be 64-bit. So make machine_desc.dma_zone_size and arm_dma_zone_size be phys_addr_t instead of unsigned long.
