2024-06-07Merge patch series "'eeprom' command improvements"Tom Rini
Marek Behún <[email protected]> says: This series contains improvements for the 'eeprom' command: - refactors - fixes - improvements - ability to use driver model EEPROMs (uclass UCLASS_I2C_EEPROM) - more flexible EEPROM layout support It should not cause any behavior change for any existing board. This series is a dependency for some DDR issue fixes for Turris Omnia. I will be sending that one separately. github PR link (with CI): https://github.com/u-boot/u-boot/pull/540 - there is a failure for test.py for sandbox sandbox_clang but it seems unrelated to these changes
2024-06-07cmd: eeprom: Extend to EEPROMs probed via driver modelMarek Behún
Extend the 'eeprom' command to allow accessing EEPROMs probed via driver model, uclass UCLASS_I2C_EEPROM. When the CONFIG_I2C_EEPROM config option is enabled (and so the i2c-eeprom driver is built), the 'eeprom' command now accepts driver model device name as EEPROM specifier for the 'eeprom' command, in addition to the legacy [[bus] devaddr] specifier. Moreover if no device specifier is given, then the first UCLASS_I2C_EEPROM device is used, if found. Signed-off-by: Marek Behún <[email protected]>

2024-06-07cmd: eeprom: Refactor eeprom device specifier parsingMarek Behún
In preparation for allowing to access eeprom by driver-model device name, refactor the eeprom device specifier parsing. Instead of filling two parameters (i2c_bus, i2c_addr), the parsing function now fills one parameter of type struct eeprom_dev_spec. Signed-off-by: Marek Behún <[email protected]>

Add a new Kconfig option EEPROM_LAYOUT_VERSIONS, and hide eeprom layout versionsing code behind it. Only print the relevant help in 'eeprom' command usage if this option is enabled. Enable this new option for cm_fx6_defconfig and cm_t43_defconfig. These are the only boards using EEPROM layout versioning. Signed-off-by: Marek Behún <[email protected]>

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 <[email protected]>

2021-07-28i2c: Rename CONFIG_SYS_I2C to CONFIG_SYS_I2C_LEGACYSimon Glass
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.

2021-02-21dm: i2c: use CONFIG_IS_ENABLED macro for DM_I2C/DM_I2C_GPIOIgor Opaniuk
Use CONFIG_IS_ENABLED() macro, which provides more convenient way to check $(SPL)DM_I2C/$(SPL)DM_I2C_GPIO configs for both SPL and U-Boot proper. CONFIG_IS_ENABLED(DM_I2C) expands to: - 1 if CONFIG_SPL_BUILD is undefined and CONFIG_DM_I2C is set to 'y', - 1 if CONFIG_SPL_BUILD is defined and CONFIG_SPL_DM_I2C is set to 'y', - 0 otherwise.

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 <[email protected]>

2016-05-20cmd: eeprom: add support for layout aware commandsNikita Kiryanov
Introduce the (optional) eeprom print and eeprom update commands. These commands are eeprom layout aware: * The eeprom print command prints the contents of the eeprom in a human readable way (eeprom layout fields, and data formatted to be fit for human consumption). * The eeprom update command allows user to update eeprom fields by specifying the field name, and providing the new data in a human readable format (same format as displayed by the eeprom print command). * Both commands can either auto detect the layout, or be told which layout to use. New CONFIG options: CONFIG_CMD_EEPROM_LAYOUT - enables commands. CONFIG_EEPROM_LAYOUT_HELP_STRING - tells user what layout names are supported Feature API: __weak int parse_layout_version(char *str) - override to provide your own layout name parsing __weak void __eeprom_layout_assign(struct eeprom_layout *layout, int layout_version); - override to setup the layout metadata based on the version __weak int eeprom_layout_detect(unsigned char *data) - override to provide your own algorithm for detecting layout version eeprom_field.c - contains various printing and updating functions for common types of eeprom fields. Can be used for defining custom layouts.
