+	  Generally, video drivers request the amount of memory they need for
+	  the frame buffer when they are bound, by setting the size field in
+	  struct video_uc_platdata. That memory is then reserved for use after
+	  relocation. But PCI drivers cannot be bound before relocation unless
+	  they are mentioned in the devicetree.
+
+	  With this value set appropriately, it is possible for PCI video
+	  devices to have a framebuffer allocated by U-Boot.
+
+	  Note: the framebuffer needs to be large enough to store all pixels at
+	  maximum resolution. For example, at 1920 x 1200 with 32 bits per
+	  pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed.
