| help |
| For ELF files, uncompressed and properly aligned data blocks |
| will be automatically be mapped directly into user space |
| whenever possible providing eXecute-In-Place (XIP) from ROM |
| of read-only segments. Data segments mapped read-write |
| (hence they have to be copied to RAM) may still be |
| compressed in the cramfs image in the same file along with |
| non compressed read-only segments. Both MMU and no-MMU |
| systems are supported. This is particularly handy for tiny |
| embedded systems with very tight memory constraints. |
| |
| The CRAMFS_MTD Kconfig option must also be enabled in a |
| 4.15+ kernel. |
