[Qemu-devel] [PULL 4/8] target-arm/helper.c: OMAP/StrongARM cp15 crn=0 cleanup

[Peter Maydell]

From: Peter Crosthwaite <address@hidden>

The if block detecting OMAP/StrongARM modifies the id_cp_reginfo
.access fields in place. So there is no need to replicate the call
to define_arm_cp_reg(). Dropped, and let the OMAP case fall through
to the normal behaviour after the in-place modification.
