Should we have a function efi_get_configuration_table(efi_guid_t *guid) that we can use to retrieve different configuration tables?
This would allow us to read the device-tree on non-x86 tables.
We may at some point also be interested in reading the EFI_RT_PROPERTIES_TABLE to find out which runtime services we are allowed to call.
Or would you prefer to all of this into scan_tables()?
Best regards
