Hi everyone, I'd like to add support for the EPYC-Rome CPU model from qemu.
The following patch adds the model to cpu_map. While this allows to use
the model, I am aware that some tests are required as well.
However I am not certain what exactly is needed. I am happy to provide
CPU flags or any required information from an EPYC 7502 system
