The Xilinx ZynqMP SoC has two main processing systems in it. The ARM processing system (which is already modeled in QEMU) and the MicroBlaze Power Management Unit (PMU). This is the inital work for adding support for the PMU. The PMU susbsystem runs along side the ARM system on hardware, but due to architecture limitations in QEMU the two instances are seperate for the time being. Let's follow the same setup we do with the ARM system, where there is an SoC device and a ZCU102 board. Although the PMU is less board specific we are still going to follow the same split as maybe in future we can connect the PMU device to the ARM ZCU102 board. As the machine will be fairly small let's keep them both together in one file.
