On MIPS, the SoC selection is a Kconfig "choice", so you can only
support one SoC family, unfortunately. I'm the one to blame for using
"depends on MIPS || COMPILE_TEST" on ingenic drivers, maybe it should
depend on MACH_INGENIC indeed, but then it should be made possible to
support more than one SoC family.

That's something that should be pointed out to the MIPS mailing list, I
believe.

Btw: Does that mean you are the new maintainer for drivers/memory/?

Cheers,
