I have a question. Is it possible to use the CAAM hardware cryptographic functions in a bare-metal application. Are there any drivers provided? I only know, that there exist drivers for linux.


Especially I like to know of it is possible, to calculate the SHA256 value for any input data in a bare-metal application.

HAB is not providing the simple calculation of a HASH value, isn't it? There are only some abstract functions to authentificate complete image.


If there exist a possibility or a driver for the hash calculation is there as well a possibility to stream the input data for the hash calculation? In the best case I like to call a function several times to stream some input data to the CAAM hash module.
