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

So, in inserting some printfs I can see that the pcie_brcmstb PCI driver is not getting probed at all. So, thinking it must have something to do with the device tree U-boot is consuming and not finding that device. I'm not that familiar with the u-boot driver model yet so any hints or tips appreciated.
Thanks, Stuart
