Porting Linux Kernel 3.8 on OMAP4 device

Recently I need to port Android 4.3+ on our OMAP4 device.

However, I found that the latest official support for OMAP4 is Android 4.1, which requires Linux Kernel 3.0.x

As far as I know, TI has working on Android 4.3 for months, but all modification are made in source code related to other devices such as DRA7xxx EVM instead of OMAP4 (I saw the latest released is 6AJ.1.1, with kernel 3.8)

I want to port kernel 3.8 on my OMAP4 device based on this BSP, but I would like to know something in advance: is there any principle for making my own BSP based on particular kernel?

I mean, how do I know I didn't make too much modification that the kernel can still be claimed as 3.8?( for example, don't modify the kernel/kernel/ folder? or can I just copy/paste the latest supported BSP of OMAP4 to the path kernel/arch/arm/mach-omap2/...)

Thanks a lot!
