QEMU provides SMBIOS tables with detailed information. We should not try to replicate them in U-Boot.
If we want to inform about U-Boot, we can add a Firmware Inventory Information (type 45) table in future.

booldefault y if ARM64default y if RISCV && 64BITWould you add QEMU x86 support as well?
On x86_64 reading the QEMU SMBIOS firmware tables does not work for me. x86 uses the qfw_pio driver instead of qfw_mmio.
x86 overwrites gd->arch.smbios_start in write_tables(). Copying SMBIOS tables from QEMU would only make sense after some refactoring by the x86 maintainers.
