For RISC-V and ARM we have

* pass-through for QEMU ACPI tables
* pass-through for QEMU SMBIOS tables
* generation of SMBIOS tables

Generation of ACPI tables in U-Boot has up now only been implemented for 
x86 but would be feasible for RISC-V boards too.

Cf. https://docs.u-boot.org/en/latest/board/emulation/acpi.html
