1.7.9.5

Some Atmel SoC support USB EHCI, add the EHCI driver to support it.

To enable the USB EHCI, add the following configuration options into board relative configuration file and remove USB OHCI options.

    #define CONFIG_USB_EHCI
    #define CONFIG_USB_EHCI_ATMEL
    #define CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS     2

---
Change since v2:
Add timeout

Change since v1:
Add WATCHDOG_RESET to avoid infinite loop.

Dear Bo Shen,

I've already acked the v2. Will pick this one ASAP and push to u-boot-atmel.

Hi Andreas,

OK!
Thanks.

OK.
Thanks

I resend the EHCI driver separately to Marex.

Dear Bo Shen,
