More information about the initial submission can be seen in the link below: https://lists.denx.de/pipermail/u-boot/2016-February/245273.html i.MX7D has an a protection feature for Manufacturing process. This feature uses asymmetric encryption to sign and verify authenticated software handled between parties. This command enables the use of such feature. The private key is unique and generated once per device. And it is stored in secure memory and only accessible by CAAM. Therefore, the public key generation and signature functions are the only functions available for the user. The manufacturing-protection authentication process can be used to authenticate the chip to the OEM's server. Command usage: Print the public key for the device. - mfgprot pubk Generates Signature over given data. - mfgprot sign <data_address> <data_size> Signed-off-by: Raul Ulises Cardenas <raul.casas@nxp.com> Signed-off-by: Breno Lima <breno.lima@nxp.com> Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Reviewed-by: Ye Li <ye.li@nxp.com> (cherry picked from commit db2dbf622d3c711b2fbd85e6814992e023479dad)
