From 91316cbb3830bb845c42da2d6eab06de56b889b0 Mon Sep 17 00:00:00 2001 From: David Edmondson Date: Tue, 16 Feb 2021 14:27:18 +0000 Subject: hw/block/pflash_cfi: Replace DPRINTF with trace events MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rather than having a device specific debug implementation in pflash_cfi01.c and pflash_cfi02.c, use the standard tracing facility.
