This patchseries implements a new board model in the mps2/mps3 family,
based on Application Note AN524:
https://developer.arm.com/documentation/dai0524/latest/
v1->v2 changes (very minor):
* renamed have-switches to has_switches
* added missing initializations of num_leds and has_switches
for new board model
Patches still needing review: 10 - 18, 20
Like the other MPS models, this board is an FPGA image; the AN524
image is based on the SSE-200, like the mps2-an521, but it is
for the MPS3 board rather than the MPS2+. The major differences
are QSPI flash and USB (which we don't model), and support for
2GB of RAM (which we do). Since the MPS3 is very similar to the
MPS2, I've implemented mps3-an524 as a subclass of TYPE_MPS2TZ_MACHINE,
sharing most of the code with mps2-an505 and mps2-an521.
The motivation for this model is two-fold:
* Linaro's Zephyr team would like it, so they can test their
code targeting the MPS3 on QEMU
* It's a useful stepping-stone towards a future MPS family model
which uses the SSE-300 and Cortex-M55. All the "make various bits
of mps2-tz.c be driven by per-board data structures rather than
hardcoding them" changes will be needed for that future board model.
This way they can be code-reviewed now, rather than making the
future patchseries even bigger (it will be pretty large even so,
because of all the "implement SSE-300 model" patches).
thanks
