Tegra186 has an on-die, 320KB, "System RAM" memory. Out of the total size, 256KB are allocated for the CPU TrustZone binaries - EL3 monitor and Trusted OS. This patch changes the base address for bl31.bin to the SysRAM base address. The carveout is too small for the Trusted OS, so we relocate only the monitor binary.

This patch add code to power on/off the secondary CPUs on the Tegra186 chip. The MCE block is the actual hardware that takes care of the power on/off sequence. We pass the constructed CPU #, depending on the MIDR_IMPL field, to the MCE CPU handlers. This patch also programs the reset vector addresses to allow the CPUs to power on through the monitor and then jump to the linux world.

This patch adds the new SiP SMC calls to allow the NS world to interact with the MCE hardware block on Tegra186 chips. Change-Id: I79c6b9f76d68a87abd57a940613ec070562d2eac Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

The CPU Complex (CCPLEX) Power Manager (Denver MCE, or DMCE) is an offload engine for BPMP to do voltage related sequencing and for hardware requests to be handled in a better latency than BPMP-firmware. There are two interfaces to the MCEs - Abstract Request Interface (ARI) and the traditional NVGINDEX/NVGDATA interface. MCE supports various commands which can be used by CPUs - ARM as well as Denver, for power management and reset functionality. Since the linux kernel is the master for all these scenarios, each MCE command can be issued by a corresponding SMC. These SMCs have been moved to SiP SMC space as they are specific to the Tegra186 SoC.

Tegra186 is the newest SoC in the Tegra family which consists of two CPU clusters - Denver and A57. The Denver cluster hosts two next gen Denver15 CPUs while the A57 cluster hosts four ARM Cortex-A57 CPUs. Unlike previous Tegra generations, all the six cores on this SoC would be available to the system at the same time and individual clusters can be powered down to conserve power.
