- rewrite of the S3C24X0 register definitions stuff
- "driver" for the built-in S3C24X0 RTC
* Patches by Yuli Barcohen, 12 Jun 2003:
- Add MII support and Ethernet PHY initialization for MPC8260ADS board
- Fix incorrect SIUMCR initialisation caused by wrong Hard Reset
configuration word supplied by FPGA on some MPC8260ADS boards
* Patch by Pantelis Antoniou, 10 Jun 2003:
