This fork adds support for CTI BSP for L4T 28.2

Merging CTI sources

This fixlayout.sh script fetches the CTI BSP sources and place them into the same folder layout than the original linux-tegra one.

Usage

git clone https://github.com/lfdmn/linux-tegra.git
cd linux-tegra
git checkout patches-l4t-r28.2
git checkout -b patches-l4t-r28.2-cti
fixlayout.sh ${PWD}

Then verify the merge and push the changes.
