* 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
