hi, The logic in efi_install_fdt() is such that with the EFI_FDT_USE_INTERNAL passed as a parameter to the function, the EFI configuration table is first checked to see if a device-tree(DT) has already been installed as the configuration table, and in case a table is found, the function returns without any other changes. However, there might be scenarios where the earlier installed configuration table might not be up-to-date, and in need of modification. One such scenario is that of adding a pmem node to the DT that is to be passed on to the OS. There could thus be a scenario where a DT that is installed as a configuration table does not have the pmem node, or it might have the wrong/stale values for the pmem node. Should there be some logic to indicate that the configuration table needs to be re-installed afresh so that these scenarios can be handled. Thoughts?
