hw/arm/pxa2xx: Replace hw_error() by qemu_log_mask()
Browse files Browse the repository at this point in the history
hw_error() calls exit(). This a bit overkill when we can log
the accesses as unimplemented or guest error.

When fuzzing the devices, we don't want the whole process to
exit. Replace some hw_error() calls by qemu_log_mask().
