ARM: ux500: Initial Device Tree support for Snowball
This provides very basic Device Tree support for ST-Ericsson's low-cost development platform, Snowball. If Device Tree for ux500 is enabled and the correct board is configured within the Device Tree blob, the correct *_init_machine() will be called. This patch is based on some original work completed by: Niklas Hernaeus <niklas.hernaeus@linaro.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Niklas Hernaeus <niklas.hernaeus@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
