In order to keep the consistency with other SoC families, maybe we can
split the 370 and XP options in two separate MACH_ARMADA_370 and
MACH_ARMADA_XP. So, in the ideal world, once all Marvell EBU SoCs are
converted to DT+mach-mvebu, we should have:

 *) arch/arm/Kconfig defines MACH_MVEBU

 *) arch/arm/mach-mvebu/Kconfig defines MACH_KIRKWOOD, MACH_DOVE,
    MACH_MX78X00, MACH_ARMADA_370, MACH_ARMADA_XP, MACH_ORION5X

Then, an user is free to build a single kernel image that supports all,
or a selection of the supported Marvell EBU SoCs.

Would that be ok with you?

If that's fine with you, then I would prefer if we keep the single
MACH_ARMADA_370_XP symbol for now, so that your pinctrl set of patches
does not depend on something else. We would do the small Kconfig option
refactoring as a follow-up set of patches. Thoughts?

Best regards,

Thomas
