Sorry for delayed response, I was really got pulled into other things, now I 
am back.

I looked at your boot-log, didn't understand how it was booting earlier for 
you -

mainline U-Boot boot log

This is important, since u-boot relocated DTB file.

Where is your DTB? Is it appended to Kernel image?
Can you try below sequence/commands from u-boot?


mmc rescan 0
fatload mmc 0 80000000 am335x-bone.dtb
fatload mmc 0 81000000 uImage
setenv bootargs console=ttyO0,115200n8 mem=256M root=/dev/mmcblk0p2 rw noinitrd rootfstype=ext3 rootwait earlyprink=serial
sendln 'bootm 81000000 - 80000000'



To build DTB files, use "make dtbs" command on your kernel home directory.
