USB patch for rpi4

[Stuart Yoder]

Hi Sylwester,

I am trying to test v4 of your patch series for USB support on rpi4:
https://patchwork.ozlabs.org/project/uboot/list/?series=179078

I am building u-boot 64-bit.  Testing on a rpi4 B 1.2 board.  But, USB is
not working for me and wanted to see if you had any ideas.  Are there
other dependencies other than just applying your patch series?

I've pasted the u-boot console output below.

>From what I can tell this board does not need the VL805 firmware
loading patch.  But, I did try those patches and it did not make any
difference.

Thanks,
Stuart
