The function display_board_info() displays the silicon revision as 2 - based on the return value from get_cpu_rev().
This is incorrect as the current Si version is 3.1
This patch displays the correct version; but does not change get_cpu_rev() to minimize the code impact.

why 8? you only have 5 chars so static char omap_revision[6] = ""; will be enough
