Hi all, 

I'm leading a project that aims to emulates a hardware that uses an Arm Cortex A9 processor. 
I though that talking with you could help me to set our directions to join efforts and with some 
luck we could contribute with something on QEMU. If someone could give some directions on
this I'll appreciate.

So, this hardware we intend to emulate doesn't need to use any specific SoC. The only 
requirement is that it must use an Arm Cortex A9 core. Is the Cortex-A9 core fully implemented 
in QEMU? My first idea was to use the xilinx board (may realview-pbx-a9 or vexpress-a9) 
because it already uses the Arm Cortex A9 processor but Im not sure if they supports graphical
display. Do they?

Then, I thought that we could write an OMAP4 implementation based on the already existing 
OMAP3 SoC as it is better organized, cleaner and has more functionality than the boards I 
mentioned before but I'm afraid that this could be much harder then just adding the graphical
parts to some of the existing ones. May be it would be possible to use OMAP3 just with a few 
tweaks so we could pass a cortex-A9 in spite of the actual cores, is that possible?

I have worked with QEMU before but never have  wrote a board machine from the scratch. In 
the case that we decide to do the OMAP4+panda emulation, what would be some logical steps 
to make the thinks working?
Kind Regards,
Erlon Cruz
