+		Sometimes, for example if the display is mounted in portrait
+		mode or even if it's mounted landscape but rotated by 180degree,
+		we need to rotate our content of the display relative to the
+		framebuffer, so that user can read the messages which are
+		printed out.
+		Once CONFIG_LCD_ROTATION is defined, the lcd_console will be
+		initialized with a given rotation from "vl_rot" out of
+		"vidinfo_t" which is provided by the board specific code.
+		The value for vl_rot is coded as following (matching to
+		fbcon=rotate:<n> linux-kernel commandline):
+		0 = no rotation respectively 0 degree
+		1 = 90 degree rotation
+		2 = 180 degree rotation
+		3 = 270 degree rotation
+
+		If CONFIG_LCD_ROTATION is not defined, the console will be

-		operation will not execute. The only way to exit this
-		hardware-protected mode is to drive W#/VPP HIGH.
