About FIT (Flattened Image Trees)
FIT is a "new", extensible, flexible U-boot Image format for representing multi-component kernel images. FIT images can represent one or more components in an image in the form of a Tree using the DT architecture. Some of the components include:
- kernel images - ramdisks - device trees - cryptographic signatures.
The FIT architecture is capable of selecting different components (a kernel X, a DTB y, a ramdisk Z) from a single Image, and dynamically booting them. The presentation material attached below provides more details, examples and usecases of FIT.
