Do both CPUs share the same RAM?

You could add a small onchip memory with reset code (embedded in the FPGA configuration) for CPU1 where it waits after reset in an endless loop until CPU0 has copied all code from EPCS to RAM for both CPUs and then changed some value in the onchip memory (or used a mutex or mailbox for signalling). But you probably have to modify the scripts for preparing the EPCS contents and bootloader code.
