 Tegra SoCs - Overview
 =====================
 
+-  .. rubric:: T186
+      :name: t186
+
+The NVIDIA® Parker (T186) series system-on-chip (SoC) delivers a heterogeneous
+multi-processing (HMP) solution designed to optimize performance and
+efficiency.
+
+T186 has Dual NVIDIA Denver 2 ARM® CPU cores, plus Quad ARM Cortex®-A57 cores,
+in a coherent multiprocessor configuration. The Denver 2 and Cortex-A57 cores
+support ARMv8, executing both 64-bit Aarch64 code, and 32-bit Aarch32 code
+including legacy ARMv7 applications. The Denver 2 processors each have 128 KB
+Instruction and 64 KB Data Level 1 caches; and have a 2MB shared Level 2
+unified cache. The Cortex-A57 processors each have 48 KB Instruction and 32 KB
+Data Level 1 caches; and also have a 2 MB shared Level 2 unified cache. A
+high speed coherency fabric connects these two processor complexes and allows
+heterogeneous multi-processing with all six cores if required.

 Trusted OS dispatcher
 =====================
 
-Tegra supports multiple Trusted OS', Trusted Little Kernel (TLK) being one of
-them. In order to include the 'tlkd' dispatcher in the image, pass 'SPD=tlkd'
-on the command line while preparing a bl31 image. This allows other Trusted OS
-vendors to use the upstream code and include their dispatchers in the image
-without changing any makefiles.
