Possibly :)

So, we have discussed in the past having the ability to get at
configuration tables when UEFI is not available. Say, for example,
that we wanted SMBIOS support on a platform with U-Boot firmware.
Since all that is needed then is a UEFI System Table with a pointer to
a configuration table array, this should be fairly straightforward to
implement statically. The other parameters would not be necessary.
It would however require minor changes to the arm64 kernel UEFI support.
