From 709e4407add7acacc593cb6cdac026558c9a8fb6 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 24 Jul 2017 15:33:12 +0100 Subject: [PATCH] target/arm: Correct MPU trace handling of write vs execute Correct off-by-one bug in the PSMAv7 MPU tracing where it would print a write access as "reading", an insn fetch as "writing", and a read access as "execute". Since we have an MMUAccessType enum now, we can make the code clearer in the process by using that rather than the raw 0/1/2 values.
