* Patch by Pierre Aubert, 12 Nov 2002:
  Add support for DOS filesystem and booting from DOS floppy disk

  Increase number of network RX buffers (PKTBUFSRX in
  "include/net.h") for EEPRO100 based boards (especially SP8240)
  which showed "Receiver is not ready" errors when U-Boot was
  processing the receive buffers slower than the network controller
  was filling them.

* Get rid of obsolete include/mpc74xx.h

  Change behaviour of NetLoop(): return -1 for errors, filesize
  otherwise; return code 0 is valid an means no file loaded - in this
  case the environment still gets updated!

    handlering
