This commit add to u-boot the support to decrypt fit image encrypted with aes. The FIT image contains the key name and the IV name. Then u-boot look for the key and IV in his device tree and decrypt images before moving to the next stage. Signed-off-by: Philippe Reynes <philippe.reynes@softathome.com>

*
|
|
* fit_conf_find_compat() attempts to find the configuration whose fdt is the
|
|
* most compatible with the passed in device tree.
|
|
*
|
|
* Example:
|
|
*
|
|
* / o image-tree
|
|
* |-o images
|
|
* | |-o fdt-1
|
|
* | |-o fdt-2
|
|
* |
|
|
* |-o configurations
|
|
* |-o config-1
|
|
* | |-fdt = fdt-1
|
|
* |
|
|
* |-o config-2
|
|
* |-fdt = fdt-2
|
|
*
|
|
* / o U-Boot fdt
|
|
* |-compatible = "foo,bar", "bim,bam"
|
|
*
|
|
* / o kernel fdt1
|
|
* |-compatible = "foo,bar",
|
|
*
|
|
* / o kernel fdt2
|
|
* |-compatible = "bim,bam", "baz,biz"
|
|
*
|
|
* Configuration 1 would be picked because the first string in U-Boot's
|
|
* compatible list, "foo,bar", matches a compatible string in the root of fdt1.
|
|
* "bim,bam" in fdt2 matches the second string which isn't as good as fdt1.
|
|
*
|
|
* As an optimization, the compatible property from the FDT's root node can be
|
|
* copied into the configuration node in the FIT image. This is required to
|
|
* match configurations with compressed FDTs.
|
|
*
|
|
* returns:
|
|
* offset to the configuration to use if one was found
|
|
* -1 otherwise
