* 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:
