We're using the FDT to pass EFI boot info that is passed in the boot params block on x86. So potentially other architectures could use the same code. How about making it someting like: #ifdef ARCH_NEEDS_EFI_FDT static efi_status_t update_fdt(efi_system_table_t *sys_table, void *orig_fdt, ... #endif so the architecture can decide whether to include it or not. --Mark -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
