[PATCH 2/6] ARM: ux500: Add board autoselection

[mathieu.poirier at linaro.org]

From: Arnd Bergmann <arnd at arndb.de>

At least one platform needs to be selected, so pick the u8500
development board if nothing else is selected. The first
menu to choose the actual platform is meaningless and can be
made invisible.
