Varun Wadekar 9c2a3d8ab7 Tegra186: implement plat_get_syscnt_freq2()
Commit f3d3b316f8 replaced
plat_get_syscnt_freq by plat_get_syscnt_freq2 on all the
upstream platforms. This patch modifies the Tegra186 code
which is not present usptream, yet.

Varun Wadekar 48afb167b3 Tegra186: handlers to get BL31 arguments from previous bootloader
This patch overrides the default handlers to get BL31 arguments from the
previous bootloader. The previous bootloader stores the pointer to the
arguments in PMC secure scratch register #53.

BL31 is the first component running on the CPU, as there isn't a previous
bootloader. We set the RESET_TO_BL31 flag to enable the path which assumes
that there are no input parameters passed by the previous bootloader.

Varun Wadekar 512da21af1 Tegra186: modify the return type for `plat_get_syscnt_freq()`
Commit c073fda1c6 upstream changed the
return type for `plat_get_syscnt_freq()` from uint64_t to unsigned
long long.

This patch modifies the return type for the Tegra186 platform.

Varun Wadekar 5cb89c5637 Tegra186: check MCE firmware version during boot
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.

Varun Wadekar e64ce3abb3 Tegra186: re-configure MSS' client settings
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.

Varun Wadekar 50402b17b8 Tegra186: implement support for System Suspend
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.

Varun Wadekar 67bc721b2b Tegra: memctrl_v2: check GPU state before VPR programming
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 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.

Varun Wadekar 3cf3183fc2 Tegra186: platform support for Tegra "T186" 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.
