serial: implement common uart post test The current arch/driver specific UART posts basically boil down to setting the UART to loop back mode, then reading and writing data. If we ignore the loop back part, the rest can be built upon the existing common serial API. So let's do just that. First add a call back for serial drivers to implement loop back control. Then write a post test that walks all of the serial drivers, puts them into loop back mode, and verifies that reading/writing at all the diff baud rates is OK. If a serial driver doesn't support loop back mode (either it can't or it hasn't done so yet), then skip it. This should allow for people to easily migrate to the new post test with existing serial drivers. I haven't touched the few already existing uart post tests as I don't the hardware or knowledge of converting them over. So I've marked the new test as weak which will allow the existing tests to override the default until they are converted. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

serial: struct serial_device: add uninit() entry for drivers Subsequent patch extends mpc512x serial driver to support multiple PSC ports. The driver will provide an uninit() function to stop the serial controller and to disable the controller's clock. Adding uninit() entry to struct serial_device allows disabling the serial controller after usage of a stdio serial device. This patch adds uninit() entry to the struct serial_device and fixes initialization of this structure in the code accordingly. Signed-off-by: Anatolij Gustschin <agust@denx.de>

mpc512x: add multi serial PSC support Extend mpc512x serial driver to support multiple PSC ports. Subsequent patches for PDM360NG board support make use of this functionality by defining CONFIG_SERIAL_MULTI in the board config file. Additionally the used PSC devices are specified by defining e.g. CONFIG_SYS_PSC1, CONFIG_SYS_PSC4 and CONFIG_SYS_PSC6. Support for PSC devices other than 1, 3, 4 and 6 is not added by this patch because these aren't used currently. In the future it can be easily added using DECLARE_PSC_SERIAL_FUNCTIONS(N) and INIT_PSC_SERIAL_STRUCTURE(N) macros in cpu/mpc512x/serial.c. Additionally you have to add code for registering added devices in serial_initialize() in common/serial.c. Signed-off-by: Anatolij Gustschin <agust@denx.de>

ZOOM2 Add serial support. Zoom2 serial is in general supplied by one of the 4 UARTS on the debug board. The default serial is from the USB connector on left side of the debug board. The USB connector will produce 2 of the 4 UARTS. On your host pick the first enumeration. The details of the setting of the serial gpmc setup are not available. The values were provided by another party. The serial port set up is the same with Zoom1. Baud rate 115200, 8 bit data, no parity, 1 stop bit, no flow. The kernel bootargs are console=ttyS3,115200n8 Signed-off-by: Tom Rix <Tom.Rix@windriver.com>

stdio/device: rework function naming convention So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.
