I'm having an issue while trying to use the lm3s811 board
emulation with qemu 0.12.3 or git. It works fine however with
qemu-0.11.1.
The problem comes from hw/armv7m.c, around line
231, the initial PC and SP are set by reading from physical memory,
however the rom data is not copied in physical memory until the reset
later on in the initialisation (comes from commit 45a50b1668822c23afc I
think). Since the initial PC is invalid, the cpu goes straight into
UsageFault instead of going to the proper reset routine.
I've made a small patch to read from rom instead of physical
memory, that fixes the issue with my test program but I'm not sure if
it's the proper thing to do, or even if it works with other arm boards.
