Ok, then the dependency should be ARCH_OMAP1, not ARCH_OMAP.

TWL4030_USB is inside drivers/usb/Kconfig and drivers/usb/otg/Kconfig,
which means in order to achieve the same on the board config you would
have to do:

default y if USB_SUPPORT && (USB || USB_GADGET) && ARCH_OMAP3

Seems to be more convoluted to me.

Besides, I think TWL4030_USB and the full description of it doesn't
give any hints to the people reading drivers/usb/otg/Kconfig what is
it used for. 'default y if ARCH_OMAP3' achieves that.

Plus, there is no big change:

config USB_MUSB_HDRC
-	select TWL4030_USB if MACH_OMAP_3430SDP

config TWL4030_USB
+	default y if ARCH_OMAP3
