Choose this option to build a kernel for release 2 or later of the
MIPS32 architecture including features from the 3.5 release such as
support for Enhanced Virtual Addressing (EVA).

help
Choose this option if you want to enable the Enhanced Virtual
Addressing (EVA) on your MIPS32 core (such as proAptiv).
One of its primary benefits is an increase in the maximum size
of lowmem (up to 3GB). If unsure, say 'N' here.
