On my way to integrate Leopard imaging camera drivers into the beagle board
image, I successfully built a minimal image with necessary camera drivers
in the image, this is all after I integrated meta-ti layer with yocto.
I finally put the files in the card and powered up the beagle board.
This is what i'm getting..

Sounds like it is booting OK but the console is wrong.
Check into why you are getting this message also
** Unable to read "uEnv.txt" from mmc 0:1 **
as the kernel args ought to get read from there:
If they are not loaded then the defaults in the kernel will get used. You might want to check these also.
Not sure about your board/setup however try using /dev/ttyO0. You can test this from U-Boot also by altering the env vars

A handy trick I found useful if you have a way to warm-reset the board [ie. RAM content is unaffected]:
In the kernel source directory, type:
grep printk_buf System.map
Then warm-reset your board after it stops outputting, and in u-boot dump the memory at whatever the address is that was reported as printk_buf symbol.
In my situation, integrating Linux onto a mach-davinci derived custom board, I found a printk message indicating it was hung waiting for something that was on the devkit but not on our board.

Back in the 2.6.32 days, the "omap" serial driver did not exist.. So
if your still setting up console as /dev/ttyO2 change it to
/dev/ttyS2..

I tried ttyO0 and ttyS2.. for some reason both did not work.. I am getting
the same output, i.e. it freezes after "...... done booting the kernel"
I made these changes through the file uEnv.txt, and therefore the error **
Unable to read "uEnv.txt" from mmc 0:1 ** doesn't come anymore..!
I was also reading
http://processors.wiki.ti.com/index.php/Kernel_-_Common_Problems_Booting_Linuxand
also enabled "
CONFIG_DEBUG_LL" in the config file using the bitbake -c menuconfig
virtual/kernel command, but that did not take much affect.

It's still likely that the console is not right. Personally I'd try a few other device nodes. As Robert mentioned, it's probably not using the /dev/ttyO? nodes because of the kernel version, so ttyS0 onwards would be what I would be looking at first.
Another possibility is to network boot Linux (i.e. TFTP the kernel then use NFS for the rootfs) then try to figure it out from that end. At least you may be able to see the serial port device nodes and work backwards.
Worse case try cross reference the serial port addresses on your hardware against what is being setup by UBoot & the kernel.

Will

How can I proceed..?
Meanwhile i will try the dumping the uboot memory as printed by the grep printk_buf System.map as told by the Christopher Pow.
Thanks so much for looking into this..!!! :) :)
