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 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.

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.

This patch registers all the FIQ interrupt sources during platform
setup. Currently we support AON and TOP watchdog timer interrupts.

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 adds support for the C6 and C7 CPU_SUSPEND states. C6 is
an idle state while C7 is a powerdown state.

The MCE block takes care of the entry/exit to/from these core power
states and hence we call the corresponding MCE handler to process
these requests. The NS driver passes the tentative time that the
core is expected to stay in this state as part of the power_state
parameter, which we store in a per-cpu array and pass it to the
MCE block.

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 support for the newer platform handler functions. Commit
I6db74b020b141048b6b8c03e1bef7ed8f72fd75b merges the upstream code which
has already moved all the upstream supported platforms over to these
handler functions.

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.
