From fae3798ac9f6de5a4cb1aa1e849d419a2bb8dbbe Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Tue, 22 Jan 2019 19:37:15 +0300 Subject: [PATCH] ARC: cache: define CONFIG_SYS_CACHELINE_SIZE as ARCH_DMA_MINALIGN Even though we don't use CONFIG_SYS_CACHELINE_SIZE in ARC-specific code it is used a lot in different drivers for alignment purposes. So we define it and make much more drivers at least compilable for ARC.
