[U-Boot] omap3 usb boot

[Michael Trimarchi]

Hi Tom

I have managed to boot dm3730 on usb (first stage), but looking at the code
I have some comment

in arch/arm/cpu/armv7/omap3/clock.c

#ifdef CONFIG_SYS_NS16550
        /* Enable UART1 clocks */
        sr32(&prcm_base->fclken1_core, 13, 1, 0x1);
        sr32(&prcm_base->iclken1_core, 13, 1, 0x1);

        /* UART 3 Clocks */
        sr32(&prcm_base->fclken_per, 11, 1, 0x1);
        sr32(&prcm_base->iclken_per, 11, 1, 0x1);

You enable clock for two uarts without take in account the real console uart
of the device. Then some lines after

sr32(&prcm_base->fclken_per, 0, 32, FCK_PER_ON);
sr32(&prcm_base->iclken_per, 0, 32, ICK_PER_ON);

That just reset all the clock using the PER_ON mask so what is done before
doesn't make sense anymore.
