* 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
