| Enables support for Flattened Image Tree (FIT). |
| |
| This option allows to boot the new uImage structure, |
| Flattened Image Tree. FIT is formally a FDT, which can include |
| images of various types (kernel, FDT blob, ramdisk, etc.) |
| in a single blob. To boot this new uImage structure, |
| pass the address of the blob to the "bootm" command. |

| Enables support for FIT Signature Verification. |
| |
| Flat Image Trees (FIT) supports hashing of images so that |
| these hashes can be checked on loading. This protects |
| against corruption of the image. However it does not prevent |
| the substitution of one image for another. |
| |
| The signature feature allows the hash to be signed with a |
| private key such that it can be verified using a public key |
| later. Provided that the private key is kept secret and the |
| public key is stored in a non-volatile place, any image can |
| be verified in this way. |
| |
| Enabling this option pulls in a dependency on libssl and |
| libcrypto, and possibly GPL/OpenSSL licensing |
| incompatibility issues. |
