zImage with FB console rotation patch applied (zi)
you may use the following kernel parameter in the Haret startup.txt:

fbcon=rotate:<n>

value 'n' accepts the following:

0 - normal orientation (0 degree)
1 - clockwise orientation (90 degrees)
2 - upside down orientation (180 degrees)
3 - counterclockwise orientation (270 degrees)

for Universal in landscape mode use fbcon=rotate:1

The angle can be changed anytime afterwards by 'echoing' the same numbers to any one of the 2 attributes found in /sys/class/graphics/fb{x}

con_rotate - rotate the display of the active console
con_rotate_all - rotate the display of all consoles

echo 0 > /sys/class/graphics/fb0/con_rotate - rotates the current console to portrait mode
echo 1 > /sys/class/graphics/fb0/con_rotate_all - rotates all active consoles to landscape mode
