If you need to add an SoC model that uses the Cortex-A55, then
yes, adding a Cortex-A55 CPU model is the right way to go.
You'll need to check whether QEMU supports all the architectural
features the A55 has. If it does then adding the CPU model is
fairly straightforward -- just a function setting the initial
ID register values plus probably something for implementation-specific
system registers.
