I was going through Arm (S)BSA tests run against sbsa-ref. Many of them
check for presence of other cards than "Root Complex Integrated
Endpoint" ones.
The "-device root-pcie-port" etc arguments can be used to add such ones
but I was wondering how to add them directly in C code. Tried to find is
there any example but looks like all systems use flat structure.
So the question is: How to add pcie-root-port and device behind it in C?
Something like those two arguments but in C:
-device pcie-root-port,id=JBHBE,slot=0,chassis=0
-device igb,bus=JBHBE
