The Tegra simulation environment has limited capabilities. This patch checks the chip's major and minor versions to decide the features to enable/disable - MCE firmware version checking is disabled and limited Memory Controller settings are enabled Change-Id: I258a807cc3b83cdff14a9975b4ab4f9d1a9d7dcf Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch checks that the system is running with the supported MCE firmware during boot. In case the firmware version does not match the interface header version, then the system halts. Change-Id: Ib82013fd1c1668efd6f0e4f36cd3662d339ac076 Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>

This patch adds a new interface to allow for making an ARI call that will enable LATIC for the chip verification software harness. LATIC allows some MINI ISMs to be read in the CCPLEX. The ISMs are used for various measurements relevant ot particular locations in Silicon. They are small counters which can be polled to determine how fast a particular location in the Silicon is.

This patch adds the chip level support for System Suspend entry and exit. As part of the entry sequence we first query the MCE firmware to check if it is safe to enter system suspend. Once we get a green light, we save hardware block settings and enter the power state. As expected, all the hardware settings are restored once we exit the power state.

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.
