[U-Boot] non SPL boot on beagleboard-xm

Hello,

I can boot u-boot built from git commit b609009801b8a00644926f49b7d0d0cc0d3d8797 successfully, but it fails with git commit ee08a8260a3a7f6ef2001cfa3e7b6137b485f40a:

Texas Instruments X-Loader 1.5.1 (Jan 24 2012 - 14:51:45) Beagle xM Reading boot sector Loading u-boot.bin from mmc

for commit ee08a8260a3a7f6ef2001cfa3e7b6137b485f40a I am disabling (or so I hope) SPL by setting #define CONFIG_SPL -> #undef CONFIG_SPL in include/configs/omap3_beagle.h

is SPL mandatory? CONFIG_SPL does not work for me to disable it

note: using MLO/SPL with current u-boot works fine

thanks, p.
