unless some new silicon solution becomes available:

1) Lattice LFXP3(or 6)
2) documented standard pinout(s) for several packages
3) specialized IP cores to support different boot media
4) pre-compiled bit streams for common scenarios

so basically you look up the 'standard' connection for the config interface
and boot media and then design in an Flash FPGA. Later you can either use or
precombiled solution or modify it for your application.

At the first step its just agreeing on 'standard' pin mapping for the Flash
FPGA that is used as the config engine. As the configurator itself is
upgradeable there is nothing that can go wrong. There is some work todo to
support different NV media and some JTAG specific stuff, but thats not so
complicated actually. Sure for booting from file system the config chip will
have some small specialued microcontroller as well.
