u-boot: EHCI timed out on TD

[Geoff Levand]

When using tftp to load a file from the network these errors are seen:

 Waiting for Ethernet connection... done.
 Using asx0 device
 TFTP from server 192.168.10.10; our IP address is 192.168.10.60
 Filename 'arndale/boot/uImage'.
 Load address: 0x40007000
 Loading: EHCI timed out on TD - token=0x8008d80
 EHCI timed out on TD - token=0x8008d80
 EHCI timed out on TD - token=0x8008d80
 EHCI timed out on TD - token=0x8008d80
 ...

The errors continue endlessly. On some attempts it will be start the load after a few of these same error messages.

If I do a 'usb start' after boot then try the tftp load I get this:

Waiting for Ethernet connection... done.

I now use this bootcmd successfully, but it takes a long time to do the usb restart and the USB timeouts:

bootcmd=echo === arndale boot ===; usb start; sleep 1; tftp 0x40007000 arndale/boot/uImage; tftp 0x41f00000 arndale/boot/dtb; bootm 0x40007000 - 0x41f00000

Tried another arndale board and get the same results.
Connected the board directly to the host with an Ethernet cross cable and get the same results.
Tried this source mod and get the same results:

 -#define USB_TIMEOUT_MS(pipe) (usb_pipebulk(pipe) ? 5000 : 1000)
 +#define USB_TIMEOUT_MS(pipe) (usb_pipebulk(pipe) ? 10000 : 1000)

I changed the switch between the host and the arndale board and the problem went away.

From a Linksys EG008W ver 3 gigabit switch to a Linksys BEFSR81 ver 2 100baseTX switch.
