+Subject: [PATCH 1/6] lenovo/x230: introduce FHD variant
+
+There is a modification for the x230 which uses the 2nd DP from the dock
+as the integrated panel's connection, which allows using a custom eDP
+panel instead of the stock LVDS display.
+
+There are several adapter boards present on the market and all of them
+uses the same method of enabling the custom eDP panel.
+
+To make this work with coreboot, the internal LVDS connector should be
+disabled in libgfxinit. The VBT has been modified as well, which allows
+brightness controls to work out of the box.
+
+The modifications done to the VBT are:
+- Remove the LVDS port entry.
+- Move the DP-3 (which is the 2nd DP on the dock) entry to the first
+  position on the list.
+- Set the DP-3 as internally connected.
+
+This has been reported to work with the following panels:
+- LP125WF2-SPB4 (1920*1080, 12.5")
+- LQ125T1JW02 (2560*1440, 12.5")
+- LQ133M1JW21 (1920*1080, 13.3")
+- LTN133HL10-201 (1920*1080, 13.3")
+- B133HAN04.6 (1920*1080, 13.3")
+- B133QAN02.0 (2560*1600, 13.3")
+
+Other eDP panels not on this list should work as well.
