* Patches by David Müller, 12 Jun 2003:
- 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: Unify status LED interface
