From: Ilya Yanok ilya.yanok@cogentembedded.com
This adds necessary config options and a new build target, am335x_evm_usbspl, to enable usb booting and fixes board_eth_init() function to take into account that we may have USB ether support in SPL now. This uses the same MAC for both cpsw and USB, in order to match ROM behavior.
The usbspl build target does not contain UART SPL, CPSW SPL or extra environment settings, so that we may fit within our binary size constraint.
-- v2: Set usb eth MAC to E-Fuse first MAC to match ROM, add am335x_evm_usbspl build target. - trini
