From 104e49d515022a2b67ee74083773207c3a01fa18 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 21 Sep 2015 13:57:45 +0200 Subject: [PATCH] axi_dmac: Remove unused address bits on AXI-Lite bus The address width for the AXI-Lite configuration bus for the core is only 14 bit. Remove the upper unused bits from the public interface. This allows infrastructure code to know about this and it might be able to perform optimizations of the interconnect based on this.
