The meaning of CONFIG_USB in U-Boot is different from that in Linux. As you see in drivers/usb/Kconfig of Linux, CONFIG_USB enables the USB host controller support, while CONFIG_USB_SUPPORT is used to enable the whole of the USB sub-system.
When I added CONFIG_USB into Kconfig by commit 6e7e9294d321 ("usb: add basic USB configs in Kconfig"), I planned to follow the Linux's convention, i.e. CONFIG_USB to enable/disable the USB host support. Then, commit 68f7c5db2d1e ("usb: Generic USB Kconfig option, that fits both host and gadget and comments") changed the logic of the CONFIG_USB to point to the whole of the USB sub-system. As a result, currently we do not have an option for USB host. This commit adds CONFIG_USB_HOST, which will be useful to compile in the USB host support code. CONFIG_USB_HOST is not referenced at all, but strangely some boards define it in board headers. I removed them because USB_HOST will be selected in Kconfig going forward.
