Anthony Zhou 50e91633ee Tegra: fix trivial misra issues
Not having U or ULL as a suffix for these enums causes
a lot of unnecessary MISRA issues. This patch adds U or
ULL suffix to these common enums to reduce number of
MISRA issues.

Pritesh Raithatha c459206d21 Tegra: smmu: support for multiple devices
This patch adds flexibility to the code to initialise multiple SMMU
devices. The base address macro name has been changed to make it
explicit that we support multiple SMMUs.

Pritesh Raithatha 986e333dc3 Tegra: smmu: platform handler for SMMU settings
This patch empowers the platforms to provide an array with the
registers that must be saved/restored across System Suspend.

Pritesh Raithatha 06803cfd02 Tegra: memctrl_v2: platform handler for MC settings
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 disables TCU prefetch for all the contexts in order
to improve SMMU performance.

Varun Wadekar 68c7de6fa9 Tegra186: save/restore BL31 context to/from TZDRAM
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.

Varun Wadekar 4122151f6d Tegra186: smmu: driver for the smmu hardware block
This patch adds a device driver for the SMMU hardware block on
Tegra186 SoCs. We use the generic ARM SMMU-500 IP block on
Tegra186. The driver only supports saving the SMMU settings
before entering system suspend. The MC driver and the NS world
clients take care of programming their own settings.
