custom i2c_init_board() routine in boards/xxx/board.c
is run early in the boot sequence.
CONFIG_SYS_I2C_BOARD_LATE_INIT
An alternative to CONFIG_SYS_I2C_INIT_BOARD. If this option is
defined a custom i2c_board_late_init() routine in
boards/xxx/board.c is run AFTER the operations in i2c_init()
is completed. This callpoint can be used to unreset i2c bus
using CPU i2c controller register accesses for CPUs whose i2c
controller provide such a method. It is called at the end of
i2c_init() to allow i2c_init operations to setup the i2c bus
controller on the CPU (e.g. setting bus speed & slave address).
CONFIG_I2CFAST (PPC405GP|PPC405EP only)
This option enables configuration of bi_iic_fast[] flags
