[ECOS] RedBoot: automatic load/execute of bootp file -- patch attached

[Grant Edwards]

I've added code to net_io.c to load/execute the file specified
by the bootp server.  It might be a good idea to add CDL code
to enable/disable this feature, but I haven't done that (I want
it enabled all the time).

IIRC, two of the routines (do_go and load_srec_image) may have
be static in the CVS sources -- so they have to be made global
for this patch to work.

Here it is if anybody wants it...
