From 3e9bb0e093a9fcc9c64e4c61fd93f973c0fc1cde Mon Sep 17 00:00:00 2001 From: Phil Edworthy Date: Fri, 4 Feb 2011 10:03:53 +0000 Subject: [PATCH 4/4] sh772x: Register phys memory with UIOMux This is patch significantly improves the performance on sh772x devices. The sh772x gfx code uses an external library (libshbeu) to access the BEU hardware. In order for this library to understand that the virtual addresses passed to it are for contiguous memory, the memory must be registered with another external library (UIOMux).
