SPL boot outputs a 'timed out in wait_for_bb: IC2_STAT' message on beagle

U-Boot SPL 2012.04-00020-gb8310b9-dirty (Apr 25 2012 - 18:49:57)
Texas Instruments Revision detection unimplemented
OMAP SD/MMC: 0
timed out in wait_for_bb: I2C_STAT=1000
reading u-boot.img

the reason for above message is that when booting from MMC, I2C needs (?) to be
initialized as well

when SPL initializes MMC (which is done in omap_hsmmc.c, mmc_board_init()) the following
is called:

        twl4030_power_mmc_init();

in order to communicate with the twl4030, I2C is necessary, but I2C has not been initialized yet in SPL

the problem can be easily fixed by #defining CONFIG_SPL_BOARD_INIT in include/configs/omap3_beagle.h

tested on beagle-xm (rev. C)
