[Qemu-devel] [PATCH 0/5] mps2: Implement FPGAIO counters and dual-timer

[Peter Maydell]

This patchset adds some missing timer and counter devices
to the MPS2 boards:

 * the MPS2 "fpgaio" register bank includes some registers
   which provide various kinds of free-running counter
 * the boards have an instance fo the CMSDK "dual timer module"

Together these are sufficient for QEMU's mps2-an505
emulation to pass the "timer test" subsection of the
self-test program which can be found (behind a clickthrough
EULA) in the Cortex-M33_IoT_kit_2_0.zip at:
 
https://developer.arm.com/products/system-design/development-boards/fpga-prototyping-boards/download-fpga-images

The dual-timer patch ended up a bit big; I can try to split
that up if people would prefer that for review.

thanks
