Thanks for reply.
Requirement : I am working for Intel Apollo Lake SOC. I need to enable a power chip which sits on I2c bus and reset the chip via gpio pin .So i need to write a slave driver to access the chip.
Static Analysis by me : Before that , i2c master should be there . I feel lpss_i2c.c can help the same. I called the lpss_i2c_init function from external/coreboot/payloads/libpayload/arch/x86/main.c and compiling with libpayload.a . let me know if i am right upto this ?. if it is then following questions are :
- how to access GPIO register to ser one or zero
- how to do i2c slave write for that chip ? any api for that ?

Welcome!
I am able to clone the coreboot and able to compile for x86 arch. I am not able to select any drivers in the menuconfig. I want compile
some
coreboot/src/drivers/i2c drivers.
I assume these are dependent on the board. Please elaborate on your goal, that means what I2C driver do you need, and what board do you work on, and give all the necessary details, like what commit hash you use.
Thanks,
Paul
