Yes, this would be best. But if you can map the I2C pins via pin multiplexing to some GPIO pins, you could use the existing soft_i2c driver. > Shall i used the same i2c driver from u-boot by modifying the register or > write my own driver for it? I have no idea, since I don't have any infos about your I2C controller. I don't know if it is similar to any of the supported controllers. So you need to check this yourself. > i found the ppc4xx_i2c structure, but can i get the information about the > each parameter or register used in that structure. >From the PPC4xx user manuals. For example the PPC440EPx. You can download those manual from the AppliedMicro (AMCC) web site.
