- 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.
