| 852 | help |
| 853 | This option enables the workaround for the 430973 Cortex-A8 |
| 854 | (r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb |
| 855 | interworking branch is replaced with another code sequence at the |
| 856 | same virtual address, whether due to self-modifying code or virtual |
| 857 | to physical address re-mapping, Cortex-A8 does not recover from the |
| 858 | stale interworking branch prediction. This results in Cortex-A8 |
| 859 | executing the new code sequence in the incorrect ARM or Thumb state. |
| 860 | The workaround enables the BTB/BTAC operations by setting ACTLR.IBE |
| 861 | and also flushes the branch target cache at every context switch. |
| 862 | Note that setting specific bits in the ACTLR register may not be |

| 1274 | help |
| 1275 | Execute-In-Place allows the kernel to run from non-volatile storage |
| 1276 | directly addressable by the CPU, such as NOR flash. This saves RAM |
| 1277 | space since the text section of the kernel is not loaded from flash |
| 1278 | to RAM. Read-write sections, such as the data section and stack, |
| 1279 | are still copied to RAM. The XIP kernel is not compressed since |
| 1280 | it has to run directly from flash, so it will take more space to |
| 1281 | store it. The flash address used to link the kernel object files, |
| 1282 | and for storing it, is configuration dependent. Therefore, if you |
| 1283 | say Y here, you must know the proper physical address where to |
| 1284 | store the kernel image depending on your own flash memory usage. |
| 1285 | |
| 1286 | Also note that the make target becomes "make xipImage" rather than |
| 1287 | "make zImage" or "make Image". The final kernel binary to put in |
