Peter Maydell eb09d533d8 hw/arm/mps2-tz: Add new mps3-an547 board 
Add support for the mps3-an547 board; this is an SSE-300 based
FPGA image that runs on the MPS3.

/* The MPS2 and MPS2+ dev boards are FPGA based (the 2+ has a bigger
* FPGA but is otherwise the same as the 2). Since the CPU itself
* and most of the devices are in the FPGA, the details of the board
* as seen by the guest depend significantly on the FPGA image.
* This source file covers the following FPGA images, for TrustZone cores:
* "mps2-an505" -- Cortex-M33 as documented in ARM Application Note AN505
* "mps2-an521" -- Dual Cortex-M33 as documented in Application Note AN521
* "mps2-an524" -- Dual Cortex-M33 as documented in Application Note AN524
* "mps2-an547" -- Single Cortex-M55 as documented in Application Note AN547
*
* Links to the TRM for the board itself and to the various Application
* Notes which document the FPGA images can be found here:
* https://developer.arm.com/products/system-design/development-boards/fpga-prototyping-boards/mps2
*
* Board TRM:

* Application Note AN547:
* https://developer.arm.com/-/media/Arm%20Developer%20Community/PDF/DAI0547B_SSE300_PLUS_U55_FPGA_for_mps3.pdf
*
* The AN505 defers to the Cortex-M33 processor ARMv8M IoT Kit FVP User Guide
* (ARM ECM0601256) for the details of some of the device layout:
* https://developer.arm.com/documentation/ecm0601256/latest
* Similarly, the AN521 and AN524 use the SSE-200, and the SSE-200 TRM defines
* most of the device layout:
* https://developer.arm.com/documentation/101104/latest/
* and the AN547 uses the SSE-300, whose layout is in the SSE-300 TRM:
* https://developer.arm.com/documentation/101773/latest/
