  10. For ELF files, uncompressed and properly aligned data blocks
  11. will be automatically be mapped directly into user space
  12. whenever possible providing eXecute-In-Place (XIP) from ROM
  13. of read-only segments. Data segments mapped read-write
  14. (hence they have to be copied to RAM) may still be
  15. compressed in the cramfs image in the same file along with
  16. non compressed read-only segments. Both MMU and no-MMU
  17. systems are supported. This is particularly handy for tiny
  18. embedded systems with very tight memory constraints.
  19. The CRAMFS_MTD Kconfig option must also be enabled in a
  20. 4.15+ kernel.
