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>

net/miiphy/serial: drop duplicate "NAMESIZE" define A few subsystems are using the same define "NAMESIZE". This has been working so far because they define it to the same number. However, I want to change the size of eth_device's NAMESIZE, so rather than tweak the define names, simply drop references to it. Almost no one does, and the handful that do can easily be changed to a sizeof(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

serial: Rename .init() and .uninit() in serial_device Rename .init() to .start() and .uninit() to .stop() in struct serial_device. This allows aligning struct serial_device with closer to struct stdio_dev. The real goal here is to allow these two structures to converge together and eventually make one to be a superset of the other.

serial: Implement default_serial_puts() U-Boot contains a lot of duplicit implementations of serial_puts() call which just pipes single characters into the port in loop. Implement function that does this behavior into common code, so others can make easy use of it. This function is called default_serial_puts() and it's sole purpose is to call putc() in loop on the whole string passed to it.

serial: ns16550: Move serial registration from serial_initialize() Move the registration of eserialN_device ports from default serial_initialize() into driver specific function called from serial_initialize(). This slims down the serial_initialize() call to a bare tracker of all possible serial port registration routines in U-Boot. The newly implemented ns16550_serial_initialize() function, which is implemented inside of the ns16550 serial driver allows encapsulation of eserialN_device within the ns16550 serial driver itself. Also, remove the exports of eserialN_device from include/serial.h as they are no longer needed. This is simply because the implementation of default_serial_console() is wrapped into the ns16550 serial driver and the default console is picked by CONFIG_SERIAL<N> macro in config file.

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.
