[U-Boot] U-Boot Minnowboard Max USB3.0 port not powering up
Hello Bin,
I am using the latest U-Boot version : u-boot-2016.07-rc1
I am seeing that after the bootup the USB port 3.0 -- the bottom one in the board is not powering up.
I compared the dmesg logs with UEFI and with u-boot. I understood that with u-boot EHCI driver is being used and with UEFI XHCI driver is used
00:1d.0 USB controller: Intel Corporation Atom Processor Z36xxx/Z37xxx Series USB EHCI (rev 11)
In the U-boot , minnowmax.dts in the fsp section I include the 'fsp,enable-xhci;' and now I am seeing that the XHCI driver is being used but still the USB port is not powered up. So I am assuming it to be other issue might be wrong pad up or it's not getting probed.
Can you please look into the issue.

You can also search the recent thread 'U-Boot on Minnowboard Max' where the solution for this is discussed - the patch needs work.
