[Qemu-devel] [PATCH] hw/arm_mptimer: Save the timer state

[Peter Maydell]

Add a missing VMSTATE_TIMER() entry to the arm_mptimer vmstate
description; this omission meant that we would probably hang on reload
when the timer failed to fire.

I know load-save does not work for Zynq Linux. This will definately
help get us closer to a working state. Might have another go to see if
it gets any further with this. Thanks.
