[U-Boot] USB support on beagleboard xM

[Christian Spielberger]

We added the following initialization of the ULPI at the bottom of 
ehci_hcd_init with no result.


	reg = ( 1 << 5 ) /* ULPI_FUNC_CTRL_RESET */
		/* FUNCTION_CTRL_SET register */
		| ( 0x05 << 16 )
		/* Write */
		| ( 2 << 22 )
		/* PORTn */
		| ((1 + 1) << 24 )
		/* start ULPI access*/
		| (1 << 31);

	ehci_writel(0x480648A4UL, reg);


The HSB2HS_CLK still is not active as we saw on the oscilloscope. Does 
anybody know how to activate the clock signal on this pin?

Help would be great.

regards,
chris.
