Bug Description
SRU:
BUG:
due to a clash between upstream hdmi detection handling and the TI BSP, hdmi video out was broken.
IMPACT:
we din't have any canonical video output, and people were thought the board was stuck
FIX:
in Ubuntu-
---------
The latest ubuntu-desktop image (20120323) fails to show video out. This report was generated from the ubuntu-server daily image so that login was possible via serial console.
