This became commit ad8a221e1f49 ("ARM: mediatek: Add config options for
mediatek SoCs.") in today's linux-next (ie, next-20150127). I noticed
because a script I use to check linux-next spotted a problem with it.

None of these four new MACH_MT* Kconfig symbols are currently used in
linux-next. I assume that patches that actually use them (either as a
Kconfig symbol or as a CONFIG_* macro) are still pending. Is that
correct?
