368 Normally with the SPL framework a legacy image is generated as part
369 of the build. This contains U-Boot along with information as to
370 where it should be loaded. This option instead enables generation
371 of a FIT (Flat Image Tree) which provides more flexibility. In
372 particular it can handle selecting from multiple device tree

391 from the U-Boot FIT image like stripping off headers or modifying the
392 size of the blob, verification, authentication, decryption etc. in a
393 platform or board specific way. In order to use this feature a platform
394 or board-specific implementation of board_fit_image_post_process() must
395 be provided. Also, anything done during this post-processing step would
396 need to be comprehended in how the images were prepared before being
397 injected into the FIT creation (i.e. the blobs would have been pre-
398 processed before being added to the FIT image).
