The branch main has been updated by kd: URL: https://cgit.FreeBSD.org/src/commit/?id=66c73af7ea59382ce5ca7cfb2eedb0491790276c commit 66c73af7ea59382ce5ca7cfb2eedb0491790276c Author: Kornel Dulęba <kd@FreeBSD.org> AuthorDate: 2022-09-02 11:08:32 +0000 Commit: Kornel Dulęba <kd@FreeBSD.org> CommitDate: 2022-09-02 11:10:32 +0000 stand: Parse BIOS revision from SMBIOS Add a smbios.bios.revision kenv, which contains the system BIOS revision as defined in SMBIOS specification, section 3.3.1. Since the revision is stored in two separate byte fields, the smbios_setenv helper can't be used. Read and construct the kenv manually instead.
