| 1146 | executing the new code sequence in the incorrect ARM or Thumb state. |

| 2029 | Execute-In-Place allows the kernel to run from non-volatile storage |
| 2030 | directly addressable by the CPU, such as NOR flash. This saves RAM |
| 2031 | space since the text section of the kernel is not loaded from flash |
| 2032 | to RAM. Read-write sections, such as the data section and stack, |
| 2033 | are still copied to RAM. The XIP kernel is not compressed since |
| 2034 | it has to run directly from flash, so it will take more space to |
| 2035 | store it. The flash address used to link the kernel object files, |
| 2036 | and for storing it, is configuration dependent. Therefore, if you |
| 2037 | say Y here, you must know the proper physical address where to |
| 2038 | store the kernel image depending on your own flash memory usage. |

| 2041 | "make zImage" or "make Image". The final kernel binary to put in |
