I copied a good information about U-Boot from mailing list thread.

======================

Hello,

For those who do not already know there is now a u-boot-ti repository
in the U-Boot GIT.
I have added leopard board support and got it approved  as well. I
have booted up a 2.6.32 kernel using this U-Boot

http://git.denx.de/?p=u-boot/u-boot-ti.git;a=summary

This will be part of my next pull request to u-boot-arm.
To be merged in Wolfgang's tree Tom Rix will have to send a pull
request to Wolfgang.

Please feel free to add more support.

Thanks,
Sandeep
