5 daysenv: Make more use of the ENV_SAVE_PTR macroTom Rini
With commit 82b2f4135719 ("env_internal.h: add alternative ENV_SAVE_PTR macro") we introduced the ENV_SAVE_PTR macro but as explained in the commit message, left full conversion for a later time. This commit makes more progress on that front by doing the remaining easy conversions to the new macro. Signed-off-by: Tom Rini <[email protected]> Changes in v2: - Reduce the number of conversions, some didn't work as expected once CMD_SAVEENV was actually disabled. - Finish converting UBI Cc Rasmus Villemoes <[email protected]>

2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

This functionality is currently unused, and has not been migrated to using DM_I2C, even. Drop this. Signed-off-by: Tom Rini <[email protected]>
2021-10-21env: Drop env_get_char_spec() and old, unused .get_char() implementationsMarek BehĂșn
Commit b2cdef4861be ("env: restore old env_get_char() behaviour") dropped the .get_char() method from struct env_driver, but left the two existing implementations (eeprom and nvram) in case someone would use them by overwriting weak function env_get_char_spec(). Since this was never done in the 3.5 years, let's drop these methods and simplify the code. Signed-off-by: Marek BehĂșn <[email protected]> Reviewed-by: Simon Glass <[email protected]>
2021-08-30Convert CONFIG_SYS_I2C_EEPROM_ADDR et al to KconfigTom Rini
- Rename usages of CONFIG_SYS_DEF_EEPROM_ADDR to CONFIG_SYS_I2C_EEPROM_ADDR based on current usage. - Convert CONFIG_SYS_I2C_EEPROM_ADDR, CONFIG_SYS_I2C_EEPROM_ADDR_LEN, CONFIG_SYS_I2C_EEPROM_BUS, CONFIG_CONFIG_SYS_EEPROM_SIZE CONFIG_SYS_EEPROM_PAGE_WRITE_BITS and CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS to Kconfig. We move these symbols around a bit and add appropriate dependencies to them. In some cases, we now add a correct default value as well. Signed-off-by: Tom Rini <[email protected]>
2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2019-12-02crc32: Use the crc.h header for crc functionsSimon Glass
Drop inclusion of crc.h in common.h and use the correct header directly instead. With this we can drop the conflicting definition in fw_env.h and rely on the crc.h header, which is already included. Signed-off-by: Simon Glass <[email protected]> Reviewed-by: Tom Rini <[email protected]>
2019-08-11env: Rename environment.h to env_internal.hSimon Glass

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]>
2018-02-16env: restore old env_get_char() behaviourGoldschmidt Simon
With multiple environments, the 'get_char' callback for env drivers does not really make sense any more because it is only supported by two drivers (eeprom and nvram). To restore single character loading for these drivers, override 'env_get_char_spec'. Signed-off-by: Simon Goldschmidt <[email protected]> Acked-by: Maxime Ripard <[email protected]>
2018-02-01env: make env drivers propagate env_import return valueSimon Goldschmidt
For multiple env drivers to correctly implement fallback when one environment fails to load (e.g. crc error), the return value of env_import has to be propagated by all env driver's load function. Without this change, the first driver that succeeds to load an environment with an invalid CRC return 0 (success) and no other drivers are checked.

2017-08-16env: Adjust the load() method to return an errorSimon Glass
The load() methods have inconsistent behaviour on error. Some of them load an empty default environment. Some load an environment containing an error message. Others do nothing. As a step in the right direction, have the method return an error code. Then the caller could handle this itself in a consistent way. Signed-off-by: Simon Glass <[email protected]>
2017-08-16env: Adjust the get_char() method to return an intSimon Glass
In principle this can fail, e.g. if the index is out of range. Adjust the driver signature to allow returning an error code. Signed-off-by: Simon Glass <[email protected]> Reviewed-by: Tom Rini <[email protected]>
2017-08-15env: Drop unused env_ptr variablesSimon Glass
This variable is declared as a global in most environment location drivers. But it is not used outside the drivers and most of the declarations are unnecessary. Also some drivers call free() on env_ptr which seems wrong since it is not in the heap. Drop the variable where possible, and all calls to free().

2017-08-15env: Create a location driver for each locationSimon Glass
Set up a location driver for each supported environment location. At present this just points to the global functions and is not used. A later patch will switch this over to use private functions in each driver. There are several special cases here in various drivers to handle peculiarities of certain boards: 1. Some boards define CONFIG_ENV_IS_IN_FAT and CONFIG_SPL_ENV_SUPPORT but do not actually load the environment in SPL. The env load code was optimised out before but with the driver, it is not. Therefore a special case is added to env/fat.c. The correct fix (depending on board testing might be to disable CONFIG_SPL_ENV_SUPPORT. 2. A similar situations happens with CONFIG_ENV_IS_IN_FLASH. Some boards do not actually load the environment in SPL, so to reduce code size we need to drop that code. A similar fix may be possible with these boards, or it may be possible to adjust the environment CONFIG settings. Added to the above is that the CONFIG_SPL_ENV_SUPPORT option does not apply when the environment is in flash. Obviously the above has been discovered through painful and time-consuming trial and error. Hopefully board maintainers can take a look and figure out what is actually needed.
