I2C real time clock (RTC) again.

That is good news. I am still having problems though. I am trying to use a PCF8563 RTC and an opencores I2C insterface instead of the 1307 and the GPIO i2C. This is still proving problematic. I looked at the latest distribution and the 1307 driver has changed significantly. I don't know if these changes are related to Hippo's patch or not. I will need to look at the actual changes in detail to see what is going on. Maybe

that will be a hint for the 8563. I am also going to try and wire in a 1307 on our opencores bus. It looks like the config.c was modified by Hippo to support either configuration. If I can get the 1307 to work, I should be able to get the 8563 to work. Thanks for the update... Alex
