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.
