2023-10-09stdio: fix stdio_deregister_dev()Heinrich Schuchardt
When copying the name of a stdio device we must ensure that it is NUL terminated before passing it to strcmp() to avoid a buffer overrun. Truncating the name field leads to failure to deregister a stdio device. When copying we must ensure that the name field sizes match.

There is a complaint in the code that iterates keyboards that we don't have the _check variant of class iterator but we in fact do, use it. In the code that iterates video devices there is an attempt to print errors but the simple iterator does not return a device when there is an error. Use the _check variant of the iterator as well.

2022-01-26usb: gadget: Add CDC ACM functionLoic Poulain
Add support for CDC ACM using the new UDC and gadget API. This protocol can be used for serial over USB data transfer and is widely supported by various OS (GNU/Linux, MS-Windows, OSX...). The usual purpose of such link is to access device debug console and can be useful for products not exposing regular UART to the user. A default stdio device named 'usbacm' is created, and can be used to redirect console to USB link over CDC ACM: > setenv stdin usbacm; setenv stdout usbacm Signed-off-by: Loic Poulain <loic.poulain@linaro.org>

2021-08-30Convert CONFIG_SYS_I2C_LEGACY to Kconfig and add CONFIG_[ST]PL_SYS_I2C_LEGACYTom Rini
First, we convert CONFIG_SYS_I2C_LEGACY to Kconfig. Next, as you cannot have SYS_I2C_LEGACY and DM_I2C at the same time, introduce CONFIG_SPL_SYS_I2C_LEGACY so that we can enable the legacy option only in SPL. Finally, for some PowerPC cases we also need CONFIG_TPL_SYS_I2C_LEGACY support. Convert all of the existing users to one or more symbols. Signed-off-by: Tom Rini <trini@konsulko.com>

It is quite confusing that CONFIG_SYS_I2C selects the legacy I2C and CONFIG_DM_I2C selects the current I2C. The deadline to migrate I2C is less than a year away. Also we want to have a CONFIG_I2C for U-Boot proper just like we have CONFIG_SPL_I2C for SPL, so we can simplify the Makefile rules. Rename this symbol so it is clear it is going away.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

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.

2014-09-10dm: Make driver model available before board_init()Simon Glass
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.

2014-07-23stdio: Provide functions to add/remove devices using stdio_devSimon Glass
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.

2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
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>
