Yes, with `INTEL_FSP_MP_INIT` enabled and `USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI` disabled it compiles fine thanks to this patch. It also executes fine but because fsp_params.c discard `USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI` it still uses PPI callback. But that's okay to verify that it compiles and that `init_cpus()` got called and worked.

It does not have any dependency. The following patch "depends" on it though.
