3. Put the slave's ucode and ENV into it's own memory space.

5. Configure PCIE system if needed.

2. Boot location should be set to one PCIE interface by RCW.
3. RCW should configure the SerDes, PCIE interfaces correctly.
4. Must set all the cores in holdoff by RCW.
5. Must be powered on before master's boot.
