In u-boot you can change the emac address base definition (EMAC_BASE_ADDR and EMAC_WRAPPER_BASE_ADDR) in arch/arm/include/asm/arch/emac_defs.h to point to second EMAC.
In kernel by default Second EMAC will be brought up by default.

Thanks Mugunthan!

        Sorry not to express my idea clearly, I mean I want to use both emac at same time, one for capture video and another to display video. And this can be supported? What should i add,Thanks!

Both the interface has to be in different domain to utilize both the EMAC as by default both Linux Network stack will be in bridge mode and use only one interface if both the interface are in same domain.

Hello

In U-boot you cannot use both the EMACs simultaneously, you change the interface by changing the base address.
In kernel both the interface is brought up as two individual interface which can be connected to separate network and can be used.

Thanks Mugunthan!

          You mean it is not necessary to modify uboot, just kernel and app? Ok, I'll try to do first, and then ask your help if necessary. Thanks!
