You should define these to the GPIO value as given directly to
the generic GPIO functions.
- CONFIG_SYS_I2C_INIT_BOARD

- When a board is reset during an i2c bus transfer
- chips might think that the current transfer is still
- in progress. On some boards it is possible to access
- the i2c SCLK line directly, either by using the
- processor pin as a GPIO or by having a second pin
- connected to the bus. If this option is defined a

- is run early in the boot sequence.

CONFIG_I2C_MULTI_BUS
This option allows the use of multiple I2C buses, each of which
