I tried to look from old messages, but I couldn't find the answer.

I have IXP425 - based board that is using U-Boot to startup. Now I need 
I2C-support to U-Boot to be able to access eeprom. I looked through code 
and noticed that IXP does not have hardware I2C-support in U-Boot. Has 
some one made the hardware support? 

I also checked the soft_i2c, but then I would need to implement gpio for 
IXP, because U-Boot doesn't seem to have them. So, if some one has 
already made the support for harware I2C, I think it's easier to 
integrate that to the my version of U-Boot than trying to get the 
soft_i2c working.

Or, if nobody has made the I2C-support, have someone made the 
gpio-support? I haven't check how much I have to modify the code if I 
try to use the gpio-code from the kernel.
