From 189d30a8e9670f1a5a1e9d3b257f14b7df7bc172 Mon Sep 17 00:00:00 2001 From: Dirk Behme <dirk.behme@de.bosch.com> Date: Tue, 25 Feb 2020 08:41:06 +0100 Subject: [PATCH] memory: renesas-rpc-if: Don't use burst mode on read Testing shows that enabling the burst mode results in a "2-byte offset" in read data. Dropping the burst mode seems to fix this.
