is slow.
+ CONFIG_LCD_ROTATION
+
+ 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
+ initialized with 0degree rotation.
+
