The FPGA tools write two kinds of SVF/JAM/STAPL files, one is ment to be replayed the to FPGA itself (what I was talking about), and one is ment to be replayed to the vendor's family of configuration PROMS (aka funky serial FLASH)
Programming the PROM in-ciruit/in-field via JTAG is normal, while programming the FPGA via JTAG is uncommon. This proposed FPGA susbsytem is about programming SRAM FPGAs, not FLASH ...
Fortunately these PROMs are on their way out, modern FPGAs can be directly connected to normal NOR FLASH and you can program the NOR via drivers/mtd :)
