This breaks all the supported peripheral boot modes. Have you tested UART/ethernet boot with this patch? I specifically wanted a separate defconfig for usb_host as it is a special case and rest of the boot modes can be supported using a single defconfig. If you don't like this approach, please create separate defconfigs for peripheral and memory boot modes.
