[Qemu-devel] Reset register configuration in embedde device

["mar.krzeminski" <mar.krzeminski@gmail.com>]

Hello,

I am new here, so sorry for dummy question...

The problem:
I have an embedded arm board simulation, I want to add a device 
simulating quite complicated reset cause logic.
This logic is used in boot process. The goal is to have possibility to 
set proper register values before virtual machine start to boot.

My ideas:
a) Create a file that will be read by device, and will be passed by 
command line and device property.
b) Use qemu monitor if possible.

Questions:
a) Is there a framework in qemu that I can use for that?
b) If not is there an idea how should be done so someone else can use 
this functionality?
c) Is it possible to use qemu monitor for this?
d) Maybe there is a device that have similar functionality?

Best regards,
Marcin
