Tearing down an unitialized rx channel causes a pending address hole event to be queued. When booting linux it will report this pending as something like "Address Hole seen by USB_OTG at address 57fff584", since u-boot did not handled this interrupt. Prevent that by not tearing down the rx channel, when not receiving.

To replicate this:

• ROMcode must not use the emac
• U-Boot must use the emac
• only on cold start

I don't know the hardware, but it sounds like a reasonable explanation. Look good to you, Tony?

Sure.
