Since the or1k shared syncrhonized timer can be updated from each vCPU via helpers we use a mutex to synchronize updates.

This patch adds automatic device tree generation support for the OpenRISC simulator. A device tree is built up based on the state of the configure openrisc simulator. This is then dumped to memory and the load address is passed to the kernel in register r3. Signed-off-by: Stafford Horne <shorne@gmail.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
