Ok, Exactly i was looking for any changes are there w.r.t BSP in linux-mainline kernel and android kernel but you made me clear with like there will be no changes in linux kernel source code including drivers,dtsi right ?? Yes i do agree i am paying for BSP to the board vendors but i was trying to get the things which needs to changes as my vendor doesnt provide support for android and i want to make android up with my device which have support for linux only.

It all depends on who you got this "BSP" from. You are paying for support from the vendor whose chip you bought, why not consult their documentation and ask them for help? > Scenario is, i want to port linux BSP to the android BSP and for that > i am trying to gather the information about the BSP, what exectly it > is, where i should change all kind of stuff At the kernel level, there is no difference between "linux bsp" and "android bsp", it's all just Linux down there. And again, ask your vendor for this help, you are paying for it already. > Hope i made you clear with what i am looking for Not really, sorry. Please be specific as to what you have tried and what did not work. thanks, greg k-h [EXT]
