[U-Boot] [PATCH] ehci-omap: fix for enabling the correct usb port

This is just a patch for the problem reported here: http://lists.denx.de/pipermail/u-boot/2012-February/117580.html originally reported by Igor.
"Looks like this is copy paste error from my side,(for port2/3 it should have been bypass for port2/3 rather its port1 set in bypass mode)"
I only submit the patch since it is missing in 2012.04-rc3 while the twister board depends on it. Maybe it is already somewhere in the reposistory, but I cannot find it.
note: the twister boards still needs an additional `usb reset`, don't know why.

I don't see any difference between the first usb start and the following resets, should there have been? Clearly, there's a problem, but lets see if we can fix all of it in time.. Thanks!

Sorry, it was incomplete. The resets are just to indicate it is never working, below is the complete listing. With the patch at least the usb works, it needs an additional reset though (hence the resets without the patch as well).

The issue was raised during the review of Govindraj's patch, it seems the wrong version was picked up.

Can you apply it for the release (this is clearly a fix) ?
Best regards, Stefano Babic

Wolfgang, can you pick this up out of patchwork? I've assigned it to you. Thanks!

Yes it was a typo and Looks like the corrected patch was not picked up as in here: http://permalink.gmane.org/gmane.comp.boot-loaders.u-boot/124620
