I would prefer to keep those CONFIG options as they are now (and are in sync with other gadgets). The problem here is that the gadget infrastructure is a bit "problematic" from the device model point of view. It has his own "structure" borrowed from Linux kernel. I've poked around and it seems like adding it to DM requires calling "g_dnl_register()" with embedded name of the gadget (like "usb_dnl_dfu"). And such call is required for each different gadget (like mass storage, dfu, fastboot). Or maybe we should add "stub" DM support to only indicate supported gadgets (like dfu, ums, etc) and leave as much code untouched as possible? > > > > Please help to remove any options you can from the headers. > > > >>> > >>>> > >>>> diff --git a/include/configs/rk3288_common.h > >>>> b/include/configs/rk3288_common.h index b5606d4..b19a34d 100644 > >>>> --- a/include/configs/rk3288_common.h > >>>> +++ b/include/configs/rk3288_common.h > >>>> @@ -74,6 +74,10 @@ > >>>> #define CONFIG_FASTBOOT_BUF_ADDR CONFIG_SYS_LOAD_ADDR > >>>> #define CONFIG_FASTBOOT_BUF_SIZE 0x08000000 > >>>> > >>>> +/* rockusb */ > >>>> +#define CONFIG_CMD_ROCKUSB > >>>> +#define CONFIG_USB_FUNCTION_ROCKUSB > >>>> + > >>>> /* usb mass storage */ > >>>> #define CONFIG_USB_FUNCTION_MASS_STORAGE > >>>> #define CONFIG_CMD_USB_MASS_STORAGE > >>>> -- > >>>> 2.7.4 > > > > Regards, > > Simon Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
