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

This patch enables overrides for APE domains to allow the chip verification
software harness (MODS) to execute its test cases.

This patch reprograms MSS to make ROC deal with ordering of
MC traffic after boot and system suspend exit. This is needed
as device boots with MSS having all control but POR wants ROC
to deal with the ordering. Performance is expected to improve
with ROC but since no one has really tested the performance,
keep the option configurable for now by introducing a platform
level makefile variable.

The memory controller loses its settings when the device enters system
suspend state.
This patch adds a handler to restore the Video Memory settings in the
memory controller, which would be called after exiting the system suspend
state.

For all APE clients (APER, APEW, APEDMAR, APEDMAW) set NO_OVERRIDE
for MC_SID_CFG as ACAST/ADAST will be setup with the required SIDs
ie. 0x7F & 0x1E.

This patch sets the Memory Controller's TXN_OVERRIDE registers
for most write clients to CGID_ADR. This ensures ordering is maintained.
In some cases WAW ordering problems could occur. There are different
settings for Tegra version A01 v A02.

The GPU is the real consumer of the video protected memory region
and it needs to be in reset to pick up the new region.
This patch checks if the GPU is in reset before we program the new
video protected memory region settings.

This patch programs the Memory controller's control registers
to disable non-secure accesses to the TZRAM. In case these
registers are already programmed by the BL2/BL30, then the
driver just bails out.

This patch adds driver for the Memory Controller (v2) in the newer
Tegra SoCs. The newer hardware uses ARM's SMMU hardware instead of
the proprietary block in the past.
