Loading programs into FPGA ram/flash

I'm currently using the evaluation version of the Cortex-M1 and my program size has exceeded the 64kB allowed for the evaluation version. Therefore, I want to load my FPGA config file with a bootloader that executes instructions starting at external SRAM or Flash. Unfortunately, I'm very new to this and there happens to be almost no example information on the Cortex-M1 besides what is provided with the evaluation trial. Basically, I want to set up my design so that I never have to recompile my FPGA design. All I want to do is update my program and then re-flash it to the board and have the processor start running that new code on a reset signal.

Basically I'm more or less looking for the approach I need to make in order to get this work and also if there are any examples I can look at.
