This allows a board to configure verified boot within the SPL using a FIT or FIT with external data. It also allows the SPL to perform signature verification without needing relocation. The board configuration will need to add the following feature defines: CONFIG_SPL_CRYPTO_SUPPORT CONFIG_SPL_HASH_SUPPORT CONFIG_SPL_SHA256 In this example, SHA256 is the only selected hashing algorithm. And the following booleans: CONFIG_SPL=y CONFIG_SPL_DM=y CONFIG_SPL_LOAD_FIT=y CONFIG_SPL_FIT=y CONFIG_SPL_OF_CONTROL=y CONFIG_SPL_OF_LIBFDT=y CONFIG_SPL_FIT_SIGNATURE=y Signed-off-by: Teddy Reed <teddy.reed@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Andreas Dannenberg <dannenberg@ti.com> Acked-by: Sumit Garg <sumit.garg@nxp.com>

The Modular Exponentiation algorithm in RSA is implemented using
|
|
driver model. So CONFIG_DM needs to be enabled by default for this
|
|
library to function.
|
|
The signing part is build into mkimage regardless of this
|
|
option. The software based modular exponentiation is built into
|
|
mkimage irrespective of this option.
