[Sound-open-firmware] [PATCH] rimage: Add support for multiple modules with code signing
Liam Girdwood
liam.r.girdwood at linux.intel.com
Tue Jan 23 22:32:11 CET 2018
Add support so that rimage can take as it's input multiple ELF modules
and merge them into a single signed manifest and firmware binary.
Remove all hard coded module descriptions. Module metadata is now read
from the ELF "module" section.
Remove duplicated and unused code for creating simple firmware images as
used on Baytrail and Haswell.

+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.
