Why have a resident config scheme at all?
Use a host pc to download. It has to be there occasionally to get the
config into the programming device.
Go straight in to the fpga using jtag.
It is a shock to discover the config device is comparable in cost to
the fpga.
if there is a cpu with flash elsewhere in the project,
using that makes sense. As long as the fpga is not essential to the
cpu boot.
A cpld and a standard flash can sometimes also be cost effective.
