* ns16550: Add WATCHDOG_RESET to putc for short watchdog timeout boardsStefan Roese2010-10-13-0/+9
| | | | | | | | | | | | | | | | | | | | Call watchdog_reset() upon newline. This is done here in putc since the environment code uses a single puts() to print the complete envrironment upon "printenv". So we can't put this watchdog call in puts(). This is needed for boards with a very short watchdog timeout, like the lwmon5 with a 100ms timeout. Without this patch this board resets in the commands with long outputs, like "printenv" or "fdt print". Note that the image size is not increased with this patch when CONFIG_HW_WATCHDOG or CONFIG_WATCHDOG are not defined since the compiler optimizes this additional code away.

* ARMV7: Fixed baudrate setting in pl01x driverMatt Waddel2010-10-13-55/+38
| | | | | | | | | The pl01x serial driver was lacking the code to switch baudrates from the command line. Fixed by simply saving the new baudrate and calling serial_init() again. Also fixed CamelCase variables, I/O accessors and comment style. Signed-off-by: Matt Waddel <matt.waddel@linaro.org>

* | serial: struct serial_device: add uninit() entry for driversAnatolij Gustschin2010-04-24-0/+6
|/ | | | | | | | | | | | | | | 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>

* Clean-up of s3c24x0 drivers excluding nand driverkevin.morfitt@fearnside-systems.co.uk2009-10-13-69/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch re-formats the arm920t s3c24x0 driver files, excluding the nand driver, in preparation for changes to add support for the Embest SBC2440-II Board. The changes are as follows: - re-indent the code using Lindent - make sure register layouts are defined using a C struct - replace the upper-case typedef'ed C struct names with lower case non-typedef'ed ones - make sure registers are accessed using the proper accessor functions - run checkpatch.pl and fix any error reports It assumes the following patch has been applied first: - [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009 - patches 1/4 and 2/4 of this series Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have any s3c2400 or s3c2410 boards but need this patch applying before I can submit patches for the SBC2440-II Board. Also, temporarily modified sbc2410x, smdk2400, smdk2410 and trab configs to use the mtd nand driver (which isn't used by any board at the moment), ran MAKEALL for all ARM9 targets and no new warnings or errors were found.

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
