It looks to me that there are at least two problems:

* Size of the produced u-boot with additional features could be too large
* Porting RX51 to DM_USB seemingly also requires porting RX51 to
device-tree (since OF_CONTROL is required), adding additional complications.

When you ask for patches, are you asking for patches that just enable
DM_USB and stub functions to make the linking succeed (although it
clearly won't result in a functional u-boot), or are you asking for
patches that enable DM_USB and OF_CONTROL, and also port the device to
device tree? To me it seems like you meant the former, but I'd like to
confirm.

Also, I believe Ivaylo and Pali are wondering if porting to DTS is a
hard requirement for porting to DM_USB (since OF_CONTROL would be required)?
