[U-Boot] EHCI hub not powering on port

[Florian Fainelli]

Hi all,

I am trying to make u-boot work with my EHCI controler and everything goes well up to when it comes to powering on the port:

According to the USB 2.0 specification paragraph 11.11, this is the correct behavior since both HUB_STATUS_LOCAL_POWER in wHubStatus and 
HUB_CHANGE_LOCAL_POWER in wHubChange are set. Issuing a port power feature to the port would have no effect.

Has anyone already met similar problems with EHCI hubs integrated to EHCI controllers ?

Thank you very much in advance.

Forgot to mention that the hardware works fine with Linux and does not require 
any specific quirk.

[U-Boot] EHCI hub not powering on port

Hi again,

Enabling CONFIG_EHCI_IS_TDI in my board configuration file made it work.
