So you should call it as "set_board_rev(BOARD_REV2)" , where:
#define BOARD_REV2 0x1
I don't think we have boards older than rev2 anymore.
Looking at the FSL kernel, there are are some tests for "if
(board_is_rev(BOARD_REV_2))"
and they should return true from what I can see from the schematics.
841 if (board_is_rev(BOARD_REV_2))
842 /* BB2.5 */
843 ret = gpio_get_value(BABBAGE_SD2_CD_2_5);
844 else
845 /* BB2.0 */
846 ret = gpio_get_value(BABBAGE_SD2_CD_2_0);
847 return ret;
With the original patch from Benoit "board_is_rev(BOARD_REV_2)" would
return falsem which would then assign the wrong SD2 card detect pin,
for example.

Fabio Estevam
