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.
