| H A D | uart_cpu_sparc64.c | diff 146972 Sat Jun 04 19:33:18 MDT 2005 marius Change the semantics of uart_cpu_getdev_keyboard() to only match SCCs/ UARTs used to connect keyboards and not also PS/2 keyboards and only return their package handle in case the keyboard is the preferred one according to the OFW but otherwise still regardless of whether the keyboard is used for stdin or not. This is simply achieved by looking at the 'keyboard' alias and returning the corresponding package handle in case it refers to a SCC/UART. This is change is done in order to give the keyboard which the OFW or the user selected in OFW on boards that support additional types of keyboards besides the RS232 ones also preference in FreeBSD. It will be also used to determine on Sun AXi and Sun AXmp boards whether a PS/2 or a RS232 is to be used as these are sort of mutual exclusive there (see upcoming commit to uart_bus_ebus.c). Note that Tatung AXi boards have the same issue but the former code happened to already give the PS/2 keyboard preference by not identifying the respective UART as keyboard system device there because the PS/2 keyboard node precedes the keyboard UART one in the OFW device tree of these boards (which isn't the case for the Sun AXi).
