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.

This option can be useful to build enviornment configurations

defconfigs with different boot environments.

Some platforms define in their U-Boot configuration that the
|
U-Boot environment should be duplicated in two locations (for
|
extra safety). Check your U-Boot configuration for the
|
CONFIG_ENV_ADDR_REDUND and CONFIG_ENV_SIZE_REDUND settings to
|
see if this is the case for your platform.
|
|
If it is the case, then you should enable this option to
|
ensure that the U-Boot environment image generated by
|
Buildroot is compatible with the "redundant environment"
|
mechanism of U-Boot.
