*(No prompt -- not directly user assignable.)*

Type: ``bool``

Help
====

This option signifies the use of an ARMv7-R processor
implementation.

From https://developer.arm.com/products/architecture/cpu-architecture/r-profile:
The Armv7-R architecture implements a traditional Arm architecture with
multiple modes and supports a Protected Memory System Architecture
(PMSA) based on a Memory Protection Unit (MPU). It supports the Arm (32)
and Thumb (T32) instruction sets.
