PS12, Line 559: struct device_operations haswell_cpu_bus_ops = {
              : 	.read_resources   = noop_read_resources,
              : 	.set_resources    = noop_set_resources,
              : 	.init             = mp_cpu_bus_init,
              : 	.acpi_fill_ssdt   = generate_cpu_entries,
              : };
Could we move this struct to `cpu/intel/haswell`? It would avoid having two redundant structs (Haswell and Broadwell use `cpu/intel/haswell` code).

We can do this as a follow-up if you prefer.
