using omap2plus defconfig with my little changes i need to boot my 
system i get the error above, also if i remove CONFIG_ARCH_OMAP2. but if 
i remove CONFIG_ARCH_OMAP3 too i get the error i reported originally 
(the kernel begins to boot, but crashes) (diff between omap2plus 
defconfig without CONFIG_ARCH_OMAP2 and omap2plus defconfig without 
CONFIG_ARCH_OMAP2, CONFIG_ARCH_OMAP3: http://paste.pocoo.org/show/352960/)

thanks
