Revision 42c4dafe803dcad82980fd8b0831a89032156f93 authored by Catalin Marinas on 01 July 2010, 12:22:48 UTC, committed by Russell King on 02 July 2010, 09:10:20 UTC
RealView boards with certain revisions of the L210/L220 cache controller
may have issues (hardware deadlock) with the mandatory barriers (DSB
followed by an L2 cache sync) when ARM_DMA_MEM_BUFFERABLE is enabled.
The patch disables ARM_DMA_MEM_BUFFERABLE for these boards.
