Hi Pantelis,

USB initialization shouldn't happen for all the boards.

The board_usb_init() follows u-boot policy, that SoC IPs (USB) are enabled and configured just before their usage.

Going back to this old thread as I dig at things again. How much of s3c_udc_probe is actually enabling hardware as opposed to registering that such hardware exists and can be enabled when we call usb_gadget_register_driver ? It looks like all of the clocking (and pin muxing?) is already being done.

I will check if s3c_udc_probe can be removed totally and replaced by usb_gadget_register_driver (since some time has passed from original UDC driver posting).
