According to include/i2c.h:
"/*
* Many boards/controllers/drivers don't support an I2C slave interface so
* provide a default slave address for them for use in common code. A real
* value for CONFIG_SYS_I2C_SLAVE should be defined for any board which does
* support a slave interface.
*/
#ifndef CONFIG_SYS_I2C_SLAVE
#define CONFIG_SYS_I2C_SLAVE 0xfe
#endif
"
As the mxc_i2c driver does not support slave mode, there is no need
to define CONFIG_SYS_I2C_SLAVE in i.MX board file.
