how much room is left on your epcs?

After compression of my hardware image it's allways fit exactly to my EPCS1 - 128KB = 1MBit.

So I can't put any software (even a little boot-loader) on the EPCS.

I could write the low-level code to access the SPI Flash myself, but I'll be glad to get ready code, if someone already write that.

2nd option. I saw SPI Flash core in OpenCores.com - it is possible to tell the SOPC Builder to reset from SPI memory with this core? - normally the SOPC Builder doesn't recognize SPI interfaced as memory.

How can I add this core to SOPC builder?
