 As documented in the :doc:`v1.4 release notes <v_1_4>`, support for building
 flashrom with make has been removed; all Makefiles have been deleted. Meson is
-now the only supported tool for building flashrom from source.

+now the only supported tool for building flashrom from source.
+
+New Feature
+===========
+Libpci 3.13.0 and onwards support ECAM to access pci registers. Flashrom will
+be moved to ECAM from IO port 0xcf8/0xcfc if the libpci version is >= 3.13.0.
+The ECAM has been supported for a very long time, most platforms should support
+it. For those platforms don't support ECAM, libpci will terminate the process by
+exit.
