| 1452 | Execute-In-Place allows the kernel to run from non-volatile storage |
| 1453 | directly addressable by the CPU, such as NOR flash. This saves RAM |
| 1454 | space since the text section of the kernel is not loaded from flash |
| 1455 | to RAM. Read-write sections, such as the data section and stack, |
| 1456 | are still copied to RAM. The XIP kernel is not compressed since |
| 1457 | it has to run directly from flash, so it will take more space to |
| 1458 | store it. The flash address used to link the kernel object files, |
| 1459 | and for storing it, is configuration dependent. Therefore, if you |
| 1460 | say Y here, you must know the proper physical address where to |
| 1461 | store the kernel image depending on your own flash memory usage. |
| 1462 | |
| 1463 | Also note that the make target becomes "make xipImage" rather than |
| 1464 | "make zImage" or "make Image". The final kernel binary to put in |
| 1465 | ROM memory will be arch/arm/boot/xipImage. |
