At $(U_BOOT)/drivers/net/bcm570x.c files header, it says 

 * Broadcom BCM570x Ethernet Driver for U-Boot.
 * Support 5701, 5702, 5703, and 5704. Single instance driver. 

--> Single Instance Driver. Does this mean it doesn't handle Interrupt. 
Sorry I cannot say more as I don't have any knowledge abt this

Also,

CONFIG_BCM570x is used in $(U_BOOT)/include/configs/BMW.h which is a MPC based Board. 

May be MPC uses interrupts for its operation inside U-Boot.
