In case SYS_I2C or DM_I2C are defined, then the "i2c " prefix of the "i2c crc32" command is missing. This patch addresses this, so that users can't get confused by the "crc32" command.
Without the patch we get
=> i2c help i2c - I2C sub-system
Usage: i2c bus [muxtype:muxaddr:muxchannel] - show I2C bus info crc32 chip address[.0, .1, .2] count - compute CRC32 checksum i2c dev [dev] - show or set current I2C bus [...]
