[Qemu-devel] [PULL 09/62] target-arm/helper.c: Allow cp15.c15 dummy override

[Peter Maydell]

From: Peter Crosthwaite <address@hidden>

The cp15.c15 space is implementation defined. Currently there is a
dummy placeholder register RAZing it. Allow overriding of this RAZ
so implementations of specific registers can take precedence.
