7b826c2f35 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.

6c768ca746 serial: push default_serial_console to drivers
Rather than sticking arch/board/driver specific logic in the common
serial code, push it all out to the respective drivers.  The serial
drivers declare these funcs weak so that boards can still override
things with their own definition.

2e5167ccad Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOC
By now, the majority of architectures have working relocation
support, so the few remaining architectures have become exceptions.
To make this more obvious, we make working relocation now the default
case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

550650ddd0 ppc4xx: Use common NS16550 driver for PPC4xx UART
This patch removes the PPC4xx UART driver. Instead the common NS16550
driver is used, since all PPC4xx SoC's use this peripheral device.

The file 4xx_uart.c now only implements the UART clock calculation
function which also sets the SoC internal UART divisors.

All PPC4xx board config headers are changed to use this common NS16550
driver now.

Tested on these boards:
acadia, canyonlands, katmai, kilauea, sequoia, zeus

e3b28e6732 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.

52cb4d4fb3 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.

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.

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.
