microcontroller for programming FPGA over JTAG

Thanks for the replies!

I want to use a microcontroller in my design to program my fpga at power on time, by reading the configuration bitstream from a nand or nor flash, then programming the fpga via passive serial connected to the microcontroller.

I need the micro to do other things in my system.

Also, I am limited in the number of pins I can break out from my PCB.

My PCB space is limited. So it would be an attractive option to use the micro's onboard USB port to allow for programming and debugging my FPGA via JTAG. Adding an additional PHY chip such as FT2232 and supporting EEPROM might be doable, but would be more elegant solution to just use the micro, since I have to have it in my design anyways...
