Change in coreboot[master]: util/cbfstool/ibpmtool: Add a new tool to assemble Boot Guard manifests
by Michał Żygowski (Code Review) 07 Aug '23

07 Aug '23

Hello Krystian Hebel, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/43403 to review the following change. Change subject: util/cbfstool/ibpmtool: Add a new tool to assemble Boot Guard manifests ...................................................................... util/cbfstool/ibpmtool: Add a new tool to assemble Boot Guard manifests OpenSSL functions tested on coreboot-sdk 1.52. The tool can create Boot Guard Manifests during build time. Takes the FIT entries as input to create IBB hash and IBB segments in the manifests. Later the entries are removed when manifests are ready.
