-About
-=====
-
-Firmware binary signing is for audio DSP is mandatory on Intel products from
-Skylake onwards. i.e. no code signing on Baytrail, Cherrytrail, Braswell,
-Haswell and Broadwell but mandatory on Skylake, Kabylake, Apollolake and
-Cannonlake.
-
-rimage can now sign firmware binaries for Apollolake and Cannonlake targets.
-This is done automatically as part of the "make bin" part of the build.
-
-
-Key Pairs
-=========
-
-The key included here is the Intel OTC (Opensource Technology Center) community
-development key. It can be freely used by anyone and is intended for reference
-board makers and firmware developers.
-
-** This key is NOT intended for locking down firmware on end user production
-devices since the "private" key has been published here. A new key pair must
-be genrated for securing firmware ! **
-
-RSA Private and Public keys are generated as follows :-
-
-openssl genpkey -algorithm RSA -out private_key.pem -pkeyopt rsa_keygen_bits:2048
-openssl rsa -pubout -in private_key.pem -out public_key.pem
-
-The public key needs to be programmed into the OEM Key manifest (cavsManifest0)
-within the BIOS in order to verify code signed with the private key. 
-Intel supplies tools to board makers to stitch the public key into the BIOS.
-
-The private key is used by rimage to sign the SOF binary. It should be kept
-secret and secure for production signing.
