From 899590816a498beb771bc85f96a019cc91bcab3d Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 30 Oct 2012 13:38:53 +0000 Subject: [PATCH] pxa: Disable dcache on palmld, palmtc, zipitz2 These platforms don't include dcache support. Define CONFIG_SYS_DCACHE_OFF so that functions don't try to call non-existent routines like flush_dcache_range().
