+	  This is the congatec Qseven 2.0 evaluation carrier board
+	  (conga-QEVAL) equipped with the conga-QA3/E3845-4G SoM.
+	  It contains an Atom E3845 with Ethernet, micro-SD, USB 2,
+	  USB 3, SATA, serial console and HDMI 1.3 video out.
+	  It requires some binary blobs - see README.x86 for details.
+
+	  Note that PCIE_ECAM_BASE is set up by the FSP so the value used
+	  by U-Boot matches that value.
