MLK-19869-1 imx6: Checking serial download booting We introduce a new arch-specific flag GD_FLG_ARCH_IMX_USB_BOOT to indicate if it is USB boot. We check the USB PHY PWD bit at early of boot stage then set that flag in global variable. So any following calling of is_boot_from_usb will return correct value.
