* Convert CONFIG_SYS_STDIO_DEREGISTER to KconfigSimon Glass2016-10-23-3/+3
| | | | | | | | | | | | This converts the following to Kconfig: CONFIG_SYS_STDIO_DEREGISTER This option should never be enabled in SPL, so use CONFIG_IS_ENABLED(SYS_STDIO_DEREGISTER) when checking the option.

* dm: stdio: Allow lazy probing of video devicesSimon Glass2016-10-11-4/+83
| | | | | | | | | | | | At present all video devices are probed on start-up. It would be better to probe a device only when it is needed. This can happen if it is referenced in the stdout environment variable, for example. Add support for this by searching for a suitable device when needed, probing it, and finding the stdio device it creates.

* dm: stdio: video: Plumb the video uclass into stdioSimon Glass2016-01-20-4/+15
| | | | | | | | | Register video drivers with stdio so that they can be used for text output. This needs to be done explicitly for now. At some point we should be able to convert stdio itself to driver model and avoid this step. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
* dm: stdio: Plumb in the new keyboard uclassSimon Glass2015-11-19-1/+30
| | | | | | | | | | | When driver model is used for keyboards we must scan the available keyboards and register them with stdio. Add code to do this. At some point (once LCD/video is converted) we should be able to convert stdio to driver model and avoid these dual data structures.

* dm: Make driver model available before board_init()Simon Glass2014-09-10-2/+16
| | | | | | | | | | | For some boards board_init() will change GPIOs, so we need to have driver model available before then. Adjust the board init to arrange this, but enable it for driver model only, just to be safe. This does create additional #ifdef logic, but it is safer than trying to make a pervasive change which may cause some boards to break. Signed-off-by: Simon Glass <sjg@chromium.org>
* stdio: Provide functions to add/remove devices using stdio_devSimon Glass2014-07-23-8/+24
| | | | | | | | | The current functions for adding and removing devices require a device name. This is not convenient for driver model, which wants to store a pointer to the relevant device. Add new functions which provide this feature and adjust the old ones to call these. Signed-off-by: Simon Glass <sjg@chromium.org>
* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-7/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>

* x86: Add CBMEM console driver for corebootVadim Bendebury2012-11-30-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch builds upon the recently introduced CBMEM console feature of coreboot. CBMEM console uses a memry area allocated by coreboot to store the console output. The memory area has a certain structure, which allows to determine where the buffer is, the buffer size and the location of the pointer in the buffer. This allows different phases of the firmware (rom based coreboot, ram based coreboot, u-boot after relocation with this change) to keep adding text to the same buffer. Note that this patch introduces a new console driver and adds the driver to the list of drivers to be used for console output, i.e. it engages only after u-boot relocates. Usiong CBMEM console for capturing the pre-relocation console output will be done under a separate change. >From Linux, run the cbmem.py utility (which is a part of the coreboot package) to see the output, e.g.: vvvvvvvvvvvvvvvvv SCSI: AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode flags: 64bit ilck stag led pmp pio ... Magic signature found Kernel command line: "cros_secure quiet loglevel=1 console=tty2... ^^^^^^^^^^^^^^^^^ Note that the entire u-boot output fits into the buffer only if the coreboot log level is reduced from the most verbose. Ether the buffer size will have to be increased, or the coreboot verbosity permanently reduced. Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* arm/microblaze/nios/nios2/sh: Remove relocation fixupsPeter Tyser2009-10-03-2/+2
| | | | | | | | | | | | | | | | | These architectures don't need relocation fixups, so reduce their codesize a bit by defining CONFIG_RELOC_FIXUP_WORKS. Also remove the reloc_off field from their global data structures as it is no longer needed. Note that the location of the standalone application jump table pointer in the global data structure is affected by this change, breaking execution of standalone applications compiled for previous versions of U-Boot. We will therefore increment XF_VERSION in the next commit, which also touches this area. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>

| | | | | | | | | | | Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code.

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-0/+251
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.
