Boot 2 CPUs from EPCS4

I have a Cyclone2 with a external Memory an a serial Flash(EPCS4)

I have 2 CPUs(cpu0 and cpu1). Is it possible to boot cpu0 and cpu1 from EPCS4??

If yes: how do I have to programm my 2 *.elf to the EPCS?

If not:

1. Can I copy the firmware_cpu1 after cpu0 has boot to ram and start it in a easy way?

2. I have space on my boar for a 2nd EPCS4. How can I put my 2nd EPCS4 in my SPOC and put the reset address to my 2nd EPCS?

3. or...has somebody an other idee for boot my cpu1? (I can`t add a parallel Flash! ....no space on my board.)

...thanks
