You should not have to make these changes at all.  Simply set
  CYGPKG_REDBOOT_ANY_CONSOLE to 0/false 
so RedBoot will only use a single console device.   Then set   
  CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL to 1
for your desired channel.

That's the whole idea behind the configuration system - source code
changes should not be required to make simple choices like this.

BTW - where did you get this port?  It's not part of the public CVS.

Finally, this question really belongs on the eCos discussion list which
is for discussing questions and issues about using eCos.  The eCos
development list is really for discussing changes to the eCos sources.
