Understood.

I wasn't aware this was pending on me (skimmed src/csm.c). I'll see what
I can do in OvmfPkg/SmbiosPlatformDxe. Doesn't seem particularly easy,
given that qemu may optionally pass smbios structures over fw_cfg (see
the -smbios option, in which case OVMF should not build, just install
them), plus there's a big number of mandatory smbios structures for
which almost a full system configuration must be collected, seemingly. I
hope edk2 will at least provide the data types.

Thanks
