[U-Boot] U-Boot Minnowboard Max USB3.0 port not powering up

[vinoth eswaran]

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.

Mit Freundlichen Grüßen
