From 1b50b0c1ceb5652e5ee985b52761a414ceecbe20 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 10 Dec 2015 14:19:20 +0100 Subject: ARM: davinci: only select WT cache if cache is enabled The DA830 chip only works if the dcache is in writethrough mode, but that produces a harmless Kconfig warning if the cache happens to be disabled: warning: (ARCH_DAVINCI_DA830) selects CPU_DCACHE_WRITETHROUGH which has unmet direct dependencies ((CPU_ARM740T || CPU_ARM920T || CPU_ARM922T || CPU_ARM925T || CPU_ARM926T || CPU_ARM940T || CPU_ARM946E || CPU_ARM1020 || CPU_FA526) && !CPU_DCACHE_DISABLE) This makes the select conditional so we don't have to worry about the warning in randconfig builds any more.
