* serial: implement common uart post testMike Frysinger2011-07-26-0/+90
| | | | | | | | | | | | | | | | | | | | | | | 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: drop serial_register return valueMike Frysinger2011-07-26-3/+1
| | | | | | | The serial_register function never fails (always return 0), so change it to a void function to avoid wasting overhead on it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* serial: push default_serial_console to driversMike Frysinger2011-07-26-68/+0
| | | | | | | | | | | | | | | | | 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.

* Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-29-1/+1
| | | | | | | | | | | 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.

* ppc4xx: Remove now unused CONFIG_UART1_CONSOLEStefan Roese2010-09-23-4/+1
| | | | | | | | CONFIG_UART1_CONSOLE was a PPC4xx specific implementation and is now removed since the move from the 4xx UART driver to the common NS16550 UART driver. Let's remove all references to this define now. Signed-off-by: Stefan Roese <sr@denx.de>
* ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-9/+1
| | | | | | | | | | | | | | | | 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 Signed-off-by: Stefan Roese <sr@denx.de>

* mpc512x: add multi serial PSC supportAnatolij Gustschin2010-04-24-0/+23
| | | | | | | | | | | | | | | | | | 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>

* Conditionally perform common relocation fixupsPeter Tyser2009-10-03-0/+2
| | | | | | | | | | | Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code. Note that this patch doesn't add #ifdefs to architecture-specific code which does not support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Add serial support.Tom Rix2009-06-12-0/+2
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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.
