The term "BSP" (Board Support Package) is not used much in linux-land. 
By BSP you are probably referring to a boot program (bootrom) and a 
linux configuration (kernel/drivers).

For a bootrom, I recommend u-boot.  There are several 8260 boards in the 
standard u-boot repository that you can start from and customize for 
your board.

If you go this route, you will want to subscribe to the u-boot-users list
https://lists.sourceforge.net/lists/listinfo/u-boot-users

> 2. where can I start to develop linux BSP.

Right from the comfort of your own linux computer!  (Developing under 
Windows/cygwin/colinux is possible, but everything is between five times 
more difficult and infinitely more difficult.  NOT recommended!)

> 3. what are tools available in market to develop linux BSP.

I would recommend downloading and installing ELDK from Denx.  It is a 
reliable and painless cross compiler (THANKS, Wolfgang & Co.!)
ftp://ftp.denx.de/pub/eldk/4.2/ppc-linux-x86/
in particular:
