Philippe Mathieu-Daudé 498661dd22 hw/arm/musicpal: Don't connect two qemu_irqs directly to the same input 
The MusicPal board code connects both of the IRQ outputs of the UART
to the same INTC qemu_irq. Connecting two qemu_irqs outputs directly
to the same input is not valid as it produces subtly wrong behaviour
(for instance if both the IRQ lines are high, and then one goes
low, the INTC input will see this as a high-to-low transition
even though the second IRQ line should still be holding it high).

This kind of wiring needs an explicitly created OR gate; add one.
