* Patch by Jim Sandoz, 07 Nov 2002:

  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
