I went through the board files and found that several boards set the
bi_arch_number in board_early_init_f() and checkboard() functions.
This means, that by adding the above, you will break them (override the
setting).
IMO, you should move this up just before the init_sequence[] array is executed.
And a small nitpick: there is a trailing white space...
