This patch set adds support for NXP's RT500 MCU [1] and the RT595
EVK[2]. More RT500 device models will be submitted in future patch sets.

The goal of this first patch set is to provide a minimal set that
allows running the NXP MCU SDK hello world example[4] and to get feedback
on a couple of new / non-standard approaches.

First, this patch set introduces a (python) tool that generates C
header files from ARM SVD files[3]. This significantly reduces the
effort to write a new device model by automatically generating:
register definitions and layout (including bit fields), register names
for easier debugging and tracing, reset register values, etc.

It also introduces unit tests for device models. To allow accessing
registers from unit tests a system bus mock is created. The main
advantage of unit tests for device models over QTest is that device
models can be tested in isolation and do not require a full qemu
machine.
