I haven't looked at how qemu supports ARM in depth. As I recall it had two versions last time I looked. As with all VM's, very specific hardware is emulated. In Qemu for ARM I believe it is totally software with some very limited choices to be changed or no choice to change hardware files. If you look at other platforms you might have files to change bios or nic cards.
See the doc's for Qemu and see if the simulated board is close enough for your use. I doubt it would be exact but maybe good enough if this board was used to build qemu for arm.
For most of these target boards, you would normally buy a few boards and get the tools. Some of the OEM's that make these boards also have doc's that tell how to develop. They may have this data already.
A board is not just a processor, associated chipset may affect the ability to test your work.
