With this commit, I assume that only SMBIOS 3.0 is supported in an EFI enabled system. # Sorry but I don't fully follow the recent SMBIOS discussion in U-Boot ML. commit aa8499680c14afa80ed731b4cfcd6934b4f93712 "efi: smbios: Drop support for SMBIOS2 tables" If QEMU provides the SMBIOS 2.1 tables, do we need to revert the above patch?
