From 4fc338e38f08f0a91e35ab386abae48eb033dbb2 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Fri, 23 May 2008 08:34:42 +0200 Subject: [ARM] Orion: DRAM mapping granularity is 64KiB, not 16MiB The DRAM base address and size fields in the CPU's MBUS bridge have 64KiB granularity, instead of the currently used 16MiB. Since all of the currently supported MBUS peripherals support 64KiB granularity as well, this patch changes the Orion address map code to stop rounding base addresses down and sizes up to multiples of 16MiB.
