In prevision of adding MUSB host and gadget to Kconfig, this move the title and help message of the USB Kconfig option to a more generic forma Adding comments to the usb Kconfig allows for a better separation and more readability in generated configs and in menuconfig. Signed-off-by: Paul Kocialkowski <[email protected]> In Linux, CONFIG_USB enables the host mode of USB. So, "depends on (USB || USB_GADGET)" makes sense. In U-Boot, since the commit above, CONFIG_USB enables the whole of USB frame-work, including host, gadget. USB_DWC3 already resides inside of if USB ... endif so, depends on (USB || USB_GADGET) does not make sense. -- Best Regards Masahiro Yamada _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
