	Repurpose the SD card slot for getting access to the UART0 serial
	console. Primarily useful only for low level u-boot debugging on
	tablets, where normal UART0 is difficult to access and requires

	---help---
	Say Y here if you've a board which uses opendrain drivers for the vga
	hsync and vsync signals. Opendrain drivers cannot generate steep enough
	positive edges for a stable video output, so on boards with opendrain
	drivers the sync signals must always be active high.

	---help---
	Say y here to enable support for the sunxi OTG / DRC USB controller
	used on almost all sunxi boards. Note currently u-boot can only have
	one usb host controller enabled at a time, so enabling this on boards
	which also use the ehci host controller will result in build errors.

config USB_KEYBOARD
	boolean "Enable USB keyboard support"
