+This property(currently used by powerpc, arm64) holds the memory range,
+the address and the size, of the IMA measurement logs that are being carried
+over to the kexec session.

+This porperty does not represent real hardware, but the memory allocated for
+carrying the IMA measurement logs. The address and the suze are expressed in
+#address-cells and #size-cells, respectively of the root node.
