> Sure, will handle in https://review.coreboot.org/c/coreboot/+/81099.

I use a static inline func to wrap the domain path setting,

struct device_path path;
        init_xeon_domain_path(&path, dp.socket, dp.stack, bus_base);

since direct assignment in struct init has some compilation restrictions and I have to use below logics instead, which cannot actually reduce the complexity.

struct device_path path;
        path.type = DEVICE_PATH_DOMAIN;
        ((union xeon_domain_path*)(&path.domain.domain))->socket = dp.socket;
        ((union xeon_domain_path*)(&path.domain.domain))->stack = dp.stack;
        ((union xeon_domain_path*)(&path.domain.domain))->bus = bus_base;
