From e6b1b38c520d85388ab6538001265cc342e81a70 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 24 Jun 2006 10:46:23 +0100 Subject: [ARM] nommu: Provide a simple flush_dcache_page implementation nommu doesn't require a complex flush_dcache_page implementation like the MMU-ful CPUs do, so provide a simplified version in nommu.c and omit flush.c from the build as appropriate.
