I am currently trying to send POST codes from Coreboot (downloaded approximately a month ago) to a Beagle I2C/SPI reader, specifically via i2c. I don't know the register needed for i2c_writeb() so I figured I would use i2c_raw_write(). In general since I have been unable to locate anything explaining the difference between the two functions I would really appriciate it if someone could explain it or direct me to where I can find documentation. I am hoping that the explaination/resource will either tell me where / or direct me to how I can figure out where the i2c_raw_write will write to (if it will just write directly to the Beagle or somewhere else)? Or would it be better to send it to a register with i2c_writeb()? I am running Coreboot on an ASROCK Mainboard, model IMB-A180.
