From 38baa4f6d69f3ba933a2578d111dc04151d9e169 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 29 Jan 2013 16:37:39 +0000 Subject: [PATCH] ARM: rpi_b: disable rpi_b dcache explicitly There appears to be no implementation of flush_dcache_range() for ARM1176, so explicitly disable dcache support to avoid references to that function from the LCD core in the next patch. This was presumably not noticed before simply because no drivers for the rpi_b were attempting DMA.
