[U-Boot] [PATCH v3 00/12] i2c: Remove old I2C support
We have about 6600 CONFIG options to convert to Kconfig at the time of writing and our target is to complete work by the end of the year. We have no hope of doing this unless we adopt a somewhat more agressive approach to dropping old boards and options.
There are a very large number of deprecated or very old options. It does not make sense to convert these to Kconfig just to carry the debt for another few years. We should remove these options.
Rather than completely dropping boards, one idea is to remove the parts of their support which have not been migrated. This was done with some Samsung boards recently, and it provided the maintainers with enough time to come in and make the changes.
CONFIG_I2C_SOFT and CONFIG_I2C_HARD are very old. This series removes them. Boards which rely on these options for I2C support lose some of their functionality. To regain it they would need to be migrated to driver model.
Changes in v3: - Update commit message so that it is unique in the series - Fix up #ifdef in cmd/eeprom.c - Drop changes to include/config headers - Rebase to master
Changes in v2: - Add new patch to adjust omap boards to not need CONFIG_I2C_HARD - Drop changes to omap board.c files - Rebase to master

This option is pretty old. It predates CONFIG_SYS_I2C which is itself deprecated in favour of driver model. Disable it for all boards.
Also drop I2C options which depend on this.

Hello Simon,
Am 13.05.2017 um 05:09 schrieb Simon Glass:
This option is pretty old. It predates CONFIG_SYS_I2C which is itself deprecated in favour of driver model. Disable it for all boards.
Also drop I2C options which depend on this.

These enable legacy I2C serial bus commands. DefiningCONFIG_HARD_I2C will include the appropriate I2C driverfor the selected CPU.This will allow you to use i2c commands at the u-bootcommand line (as long as you set CONFIG_CMD_I2C inCONFIG_COMMANDS) and communicate with i2c based realtimeclock chips.

If you do not have i2c muxes on your board, omit this define.-----under removal:
-- Legacy I2C Support: CONFIG_SOFT_I2C
NOTE: It is intended to move drivers to CONFIG_SYS_I2C whichprovides the following compelling advantages:- more than one i2c adapter is usable- approved multibus support- better i2c mux support** CONFIG_SOFT_I2C is now being removed **With CONFIG_SOFT_I2C you will need to defineCONFIG_SYS_I2C_SPEED to be the frequency (in Hz) at which youwish your i2c bus to run and CONFIG_SYS_I2C_SLAVE to be theaddress of this node (ie the CPU's i2c node address).Now, the u-boot i2c code for the mpc8xx(arch/powerpc/cpu/mpc8xx/i2c.c) sets the CPU up as a master nodeand so its address should therefore be cleared to 0 (See,eg, MPC823e User's Manual p.16-473). So, setCONFIG_SYS_I2C_SLAVE to 0.When a board is reset during an i2c bus transferchips might think that the current transfer is stillin progress. Reset the slave devices by sending startcommands until the slave device responds.That's all that's required for CONFIG_HARD_I2C.+- Legacy I2C Support: If you use the software i2c interface (CONFIG_SYS_I2C_SOFT) then the following macros need to be defined (examples are from include/configs/lwmon.h):
