| 1212 | This option enables the workaround for the 430973 Cortex-A8 |
| 1213 | (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb |
| 1214 | interworking branch is replaced with another code sequence at the |
| 1215 | same virtual address, whether due to self-modifying code or virtual |
| 1216 | to physical address re-mapping, Cortex-A8 does not recover from the |
| 1217 | stale interworking branch prediction. This results in Cortex-A8 |
| 1218 | executing the new code sequence in the incorrect ARM or Thumb state. |
| 1219 | The workaround enables the BTB/BTAC operations by setting ACTLR.IBE |
| 1220 | and also flushes the branch target cache at every context switch. |
