This patch empowers the platforms to provide the settings (e.g. stream ID,
security setting, transaction overrides) required by the Memory Controller
driver. This allows the platforms to program the Memory Controller as per
their needs and makes the driver scalable.

This patch moves the TSA block's macros from memctrl_v2.h to
tegra_def.h in the Tegra186 tree.

This patch moves the chip specific memory controller driver defines to
the appropriate tegra_def.h files, for future compatibility.

This patch enables the configuration settings for the TZRAM
aperture by programming the base/size of the aperture and
restricting access to it. We allow only the CPU to read/write
by programming the access configuration registers to 0.

This patch adds support to save the BL31 state to the TZDRAM
before entering system suspend. The TZRAM loses state during
system suspend and so we need to copy the entire BL31 code to
TZDRAM before entering the state.

In order to restore the state on exiting system suspend, a new
CPU reset handler is implemented which gets copied to TZDRAM
during boot. TO keep things simple we use this same reset handler
for booting secondary CPUs too.

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.

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.

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.
