This will trip the assert in register_cp_regs_for_features():
if (arm_feature(env, ARM_FEATURE_MPU)) {
/* These are the MPU registers prior to PMSAv6. Any new
* PMSA core later than the ARM946 will require that we
* implement the PMSAv6 or PMSAv7 registers, which are
* completely different.
*/
assert(!arm_feature(env, ARM_FEATURE_V6));
...indicating that R4 support is more work than is contained
in this patch :-)
