Until now, the SoC selection for the ARCH_MVEBU platforms has been done in the config header. Using CONFIG_ARMADA_XP in a non-clear way. As it needed to get selected for AXP and A38x based boards. This patch now changes this to move the SoC selection to Kconfig. And also uses CONFIG_ARCH_MVEBU as a common define for both AXP and A38x. This makes things a bit clearer - especially for new board additions. Additionally the defines CONFIG_SYS_MVEBU_DDR_AXP and CONFIG_SYS_MVEBU_DDR_A38X are replaced with the already available CONFIG_ARMADA_38X and CONFIG_ARMADA_XP. And CONFIG_DDR3 is removed, as its not referenced anywhere. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>
