* Patch by Christian Hohnstaedt, 23 Apr 2004:

  JFFS2 speed enhancements:
  - repair header CRC calculation in jffs2_1pass.c
  - add eraseblock size to the partition information to skip empty
    eraseblocks if we find more then 4k of free space.
  - The JFFS2 scanner is now fast enough to remove the spinning wheel
    so #ifdef-ed out.
  - add watchdog calls in long running loops

* Patch by Philippe Robin, 22 Apr 2004:
  Fix ethernet configuration for "versatile" board

* Patch by Kshitij Gupta, 21 Apr 2004:
  Remove busy loop and use MPU timer fr usleep() on OMAP1510/1610 boards

* Patch by Steven Scholz, 24 Feb 2004:
  Fix a bug in AT91RM9200 ethernet driver:
  The MII interface is now initialized before accessing the PHY.

* Cleanup PCI ID's
