Ninad did a nice how to :

   https://lore.kernel.org/qemu-devel/20230331161319.2250334-4-ninadpalsule@us.ibm.com/

If you want to try, the patches are on this branch :

   https://github.com/legoater/qemu/commits/aspeed-8.0

and they should reach the QEMU OpenBMC repo at some point in time.


Joel also provided a simple test case :

   https://lore.kernel.org/qemu-devel/20230328120844.190914-1-joel@jms.id.au/

using the ast2600-evb machine.

Cheers,
