[U-Boot] [PATCH 3/3] omap3_beagle: enable EHCI and USB storage.

[Alexander Holler]

The reset sequence/configuration for ehci is highly board specific,
so this will be done in the source for the board, instead of
introducing several CONFIG_* which would be needed to make those
few lines in beagle.c usable across different OMAP boards.

[U-Boot] [PATCH 3/3] omap3_beagle: enable EHCI and USB storage.

[Paulraj, Sandeep]

Thanks

Pushed to u-boot-ti.
