Subject: * Patch by Andreas Oberritter, 09 Nov 2002:   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!

* Patches by Jon Diekema, 9 Nov 2002:
  - improve ADC/DAC clocking on the SACSng board to align
    the failing edges of LRCLK and SCLK
  - sbc8260 configuration tweaks
  - add status LED support for 82xx systems
  - wire sspi/sspo commands into command handler; improved error
    handlering
  - add timestamp support and alternate memory test to the
    SACSng configuration
