From bf4ea7ed210f27df35315b8089662e84ba7dfadb Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 18 Jul 2016 12:53:31 +0200 Subject: [PATCH] x86: cache.h: Add default for CONFIG_SYS_CACHELINE_SIZE Don't just define ARCH_DMA_MINALIGN but also CONFIG_SYS_CACHELINE_SIZE if it's undefined. This is needed for the xhci driver to compile.
