OMAP_TAGS should vanish soon since they're not generic arm tags. Most of them can be converted to a platform_data or parsed from a command line like e.g. serial tag. For OMAP_TAG_USB we just let boards call omap_usb_init() passing a pointer to omap_usb_config. Patch updated by Tony for mainline, basically make n770 and h4 compile. Also folded in a fix for OSK by David Brownell <dbrownell@users.sourceforge.net>. Signed-off-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
