Sorry for delayed response, I went out of station, supposed to come back on 
Monday itself but due to some known reason couldn't make it. I have just 
resumed my work today. Sorry for inconvenience...

Coming back to your question,

Omap2plus_defconfig should work for you, you should get linux prompt with 
ramdisk image (which I use). Just to be more clear, and for your reference I am pasting steps which I use for testing, 

Build Steps:
 - make ARCH=arm CROSS_COMPILE=<toolchain> distclean
 - make ARCH=arm CROSS_COMPILE=<toolchain> omap2plus_defconfig
 - make ARCH=arm CROSS_COMPILE=<toolchain> uImage-dtb.am335x-evm
   (Since I am not using DT aware u-boot)

Use the ramdisk image to boot kernel, since we do not have support for any 
storage devices in the mainline.

U-Boot commands to boot:
setenv bootcmd 'mmc rescan 0; fatload mmc 0 81000000 uImage; fatload mmc 0 82000000 ramdisk-pm.gz; bootm 81000000'
setenv bootargs 'console=ttyO0,115200n8 mem=128M root=/dev/ram rw initrd=0x82000000,16MB ramdisk_size=65536 earlyprintk=serial'

Hope this will help you to boot the kernel on BeagleBone.
