The individual SoC dependency in Kconfig hardly scales anymore.
Instead of having such a fine grained dependency just depend
on ARCH_MXC and risk that the uninformed user has to look in
the help text to figure out which driver is the correct one.

[...]

?config MX3_IPU
? ? ? ?bool "MX3x Image Processing Unit support"
- ? ? ? depends on ARCH_MX3
+ ? ? ? depends on ARCH_MXC
? ? ? ?select DMA_ENGINE
? ? ? ?default y
? ? ? ?help

You could instead make it depend on HAVE_MX3_IPU and select this
symbol from relevant model config. Leaving it for the users is making
every one of them redo the work you already did.
