USB1 is not used on AM57xx GP EVM in device mode. Enabling DWC3 USB support for AM57xx EVM gives the following warnings:
CC board/ti/am57xx/board.o ../board/ti/am57xx/board.c:448:27: warning: 'usb_otg_ss1' defined but not used [-Wunused-variable] static struct dwc3_device usb_otg_ss1 = { ^ ../board/ti/am57xx/board.c:455:32: warning: 'usb_otg_ss1_glue' defined but not used [-Wunused-variable] static struct dwc3_omap_device usb_otg_ss1_glue = { ^ ../board/ti/am57xx/board.c:461:33: warning: 'usb_phy1_device' defined but not used [-Wunused-variable] static struct ti_usb_phy_device usb_phy1_device = {
Fix it by getting rid of USB1 related structures from board.c. They can be added back if there is a need for them.
