Enable DM USB, DM PHY and USB gadget support in imx8mm-mx8menlo SPL to let the board continue SDP loading of second stage after the first stage was loaded by BootROM SDP implementation. It is not possible to jump back into BootROM v1 and let the BootROM implementation continue the SDP loading, all this has to be performed by the U-Boot CI HDRC controller driver and SDP protocol implementation, both of which fit into the SPL just barely.
With this patch, it is possible to start both U-Boot SPL and U-Boot using e.g. uuu on this board as follows:
$ uuu -brun spl flash.bin

This is great, I was able to test SPL SDP on an imx8mm-evk after applying these same changes to imx8mm-evk and reducing the SPL size.
Fabio,
Can you tell me what you did to reduce the SPL size?
CONFIG_LTO from the other patch
