From 618119c2d39dc015e3bb27b69ab2000a6ae2289a Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 20 Feb 2017 15:35:59 +0000 Subject: armv7m: Make ARMv7M object take memory region link Make the ARMv7M object take a memory region link which it uses to wire up the bitband rather than having them always put themselves in the system address space.
