No. EPCS contains a default boot copier which I said earlier.

Please take a look at this,

Though the default EPCS boot copier works, it is not easy to update 
u-boot(-dtb).bin image with u-boot sf command. So I used a modified 
version, which copies the u-boot image from a fixed location on EPCS/sf 
to the end of DRAM.

Best regards,
