This patch adds full DM support to the SPL on MVEBU. Currently only serial is supported. Other drivers will follow. This patch also adds the necessary config values for the DEBUG UART to the MVEBU defconfig files. This came in handy while implementing this DM support. Additionally, the mvebu specific SPL linker script is removed and this common one is used instead: arch/arm/cpu/u-boot-spl.lds This common linker script already handles all special cases. No need to reinvent the wheel for MVEBU here.
