BCM53101E RvMII mode

Hi experts,


I'm using BCM53101E in my board, it is connected with CPU by RvMII mode, and the other 4 PHY ports are connected with other targets.


1) I want the CPU can talk with all targets (I'm using 4 of 5), and targets won't need to talk with each other. There are so many registers, can you tell me how to set it, or is there any tool I can use?


 2) The uboot in my CPU is up, I found one topic about BCM53101P, so I made the same setting by Pseudo-PHY MDC/MDIO interface. So the connection will be like: 

            CPU (UBOOT) - (RvMII) - BCM53101E - (RJ45) - network (A switch in my lab)

 If I ran DHCP command in UBOOT, can I get IP address assigned? I found I could get IP address.

  1. set Reg(0x00: 0x08)=0x1C
  2. set Reg(0x00: 0x0B)=0x02
  3. set Reg(0x00: 0x0E)=0x87   (also tried 0x83)
  4. set Reg(0x02: 0x00)=0x02
