The default serial driver is the one that works best on the hardware, but it unfortunately does not work on spike. So to use spike you need to enable the old serial driver.

Does "make sim" work? I think running the kernel directly without an initram won't do much interesting. make sim will create a buildroot initram with an init that the kernel can run.
