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
