From b92e062a6f53251feef0969135b539d1fb33f7d6 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Thu, 5 Apr 2012 19:52:54 +0200 Subject: target-lm32: fix debug memory access CPU models which have the LM32_FLAG_IGNORE_MSB flag set will shadow the lower 2GB to the upper 2GB memory space. This will fix the debug memory access used by qemu console and GDB to match this behaviour.
