Move the registration of serial_XXuart 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 pxa_serial_initialize() function, which is
implemented inside of the serial_pxa driver allows encapsulation
of serial_XXuart within the serial_pxa driver itself.
Also, remove the exports of serial_XXuart from include/serial.h
as they are no longer needed. This is simply because the implementation of
default_serial_console() is wrapped into the serial_pxa driver and
the default console is picked by CONFIG_CONS_IDX macro in config file.

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.

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().

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.

The multi serial support has a "ctlr" field which almost no one uses,
but everyone is forced to set to useless strings. So punt it.
Funny enough, the only code that actually reads this field (the mpc8xx
driver) has a typo where it meant to look for the SCC driver. Fix it
while converting the check to use the name field.

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.

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.

Zoom2 needs to use these declarations and the include directory is a

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.

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.

Patch by Martin Krause, 8 Jun 2006
This patch supports two serial consoles on boards with
a MPC5xxx CPU. The console can be switched at runtime
by setting stdin, stdout and stderr to the desired serial
interface (serial0 or serial1). The PSCs to be used as
console port are definded by CONFIG_PSC_CONSOLE
and CONFIG_PSC_CONSOLE2.
See README.serial_multi for details.
