Cortex-M0 DesignStart Eval


I have download the Cortex-M0 DesignStart Eval file (AT510-MN-80001-r2p0-00rel0),
and read the ARM FPGA board (MPS2+) datasheet.

The MPS2+ have many peripheral devices but we don't need it,
so we want made a platform for our use.

The user guide (arm_cortex_m0_designstart_eval_fpga_user_guide) described "Decryption key" section,
did this section means DesignStart Eval code just only fit to MPS2+ ?
Or, the decryption key has another function ?

Could the DesignStart Eval be porting to another FPGA board ?
