424 | Allows doing any sort of manipulation to blobs after they got extracted | |
425 | from the U-Boot FIT image like stripping off headers or modifying the | |
426 | size of the blob, verification, authentication, decryption etc. in a | |
427 | platform or board specific way. In order to use this feature a platform | |
428 | or board-specific implementation of board_fit_image_post_process() must | |
429 | be provided. Also, anything done during this post-processing step would | |
430 | need to be comprehended in how the images were prepared before being | |
431 | injected into the FIT creation (i.e. the blobs would have been pre- | |
432 | processed before being added to the FIT image). | |
