ARM: ux500: Move all Device Tree booting into cpu-db8500
To aid the kernel in its effort to move to DT only booting, we're transplanting all Device Tree related code to cpu-db8500 which will remain persistent throughout the transition. This change paths the way for complete removal of board-mop500, which will be done once the all DMA settings are moved into the respective DT source files. Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
