What is the status of the PCIE Driver here: https://github.com/polarfire-soc/platform/tree/main/drivers/mss/pf_pcie

[haroldnelson-2021]

How difficult will it be to use this driver in a BareMetal PF SOC system for a Root Port?

Since this PCIE Root Port is not Linux-based, the "PCIE shim" block can be deleted from the fabric, right, i.e. 32-bit addressing is fine?
