From d337a09c30a04d14e2c35b7517105c6b2e3e48dd Mon Sep 17 00:00:00 2001 From: "Wu, Josh" Date: Mon, 19 May 2014 19:51:28 +0800 Subject: [PATCH] ARMv7: at91: enable ICache and DCache. MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit For at91 armv7 SoC (SAMA5D3x), only LCD and macb used DMA. Now as the lcd and macb driver already support dcache. So we can enable dcache now. Also we can enable icache without any problem.
