This option is required for mvebu SoC and is not user (de)-selectable.
So please do not define it in each individual mvebu board. It would make
it harder to introduce a new mvebu board into U-Boot. Instead enable it
for mvebu SoCs like it was before this change. It can be done e.g. by
"select" Kconfig keyword in mvebu Kconfig file.
