the coreboot code that are should go into the notes between now and

+Upcoming release - coreboot 4.19
+========================================================================

+Plans for Code Deprecation
+--------------------------
+
+
+### Intel Icelake SoC & Icelake RVP mainboard
+
+Intel Icelake is unmaintained. Also, the only user of this platform ever
+was the Intel CRB (Customer Reference Board). From the looks of it the
+code was never ready for production as only engineering sample CPUIDs
+are supported. This reduces the maintanence overhead for the coreboot
+project.
+
+Intel Icelake code will be removed with release 4.19 and any maintenence
+will be done on the 4.19 branch. This consists of the Intel Icelake SoC
+and Intel Icelake RVP mainboard.
+
+
+### Intel Quark SoC & Galileo mainboard
+
+The SoC Intel Quark is unmaintained and different efforts to revive it
+failed.  Also, the only user of this platform ever was the Galileo
+board.
+
+Thus, to reduce the maintanence overhead for the community, support for
+the following components will be removed from the master branch and will
+be maintained on the release 4.20 branch.
+
+  * Intel Quark SoC
+  * Intel Galileo mainboard
