Indeed, my serial debug patches are unrelated to this early_serial_init() patch. Mind you I think setting up the serial subsystem dynamically rather than statically has the potential to make things a good deal neater than the current maze of twisty little include files. However there is a problem at the moment, because early_serial_init() won't work if serial.o is compiled as a module. -- David Gibson | For every complex problem there is a david@gibson.dropbear.id.au | solution which is simple, neat and | wrong. -- H.L.
