[U-Boot] MPC8541 - Ethernet on FCC

[Alemao]

Hi all,

My MPC8541 board has 4 ethernet ports, 2 TSEC's e 2 FCC's. Each one is
connected to a PHY, and all PHY's are connected to the MDIO bus.

For TSEC's, PHY address is defined with:

#define TSEC1_PHY_ADDR		4
#define TSEC1_PHY_ADDR		2

But I didn't find where to set FCC PHY address. Is it not needed?

In almost all boards thats use ethernet FCC, I saw the flag FCC_PSMR_LPB seted:

#define CONFIG_SYS_FCC_PSMR		(FCC_PSMR_FDE | FCC_PSMR_LPB)

Why loopback is seted by default?

Cheers,
