This patch converts Tegra platforms to support native
GICv2 drivers. This involves removes Tegra's GIC driver
port platforms to use interrupt_props

This patch adds the Tegra micro-seconds controller to the
memory map. This allows us to use the delay_timer functionality.

The NVidia Tegra 210 SoC contains Cortex-A53 CPUs which are affected by
erratum 855873.
Enable the workaround that TF provides to fix this erratum.

allocated by the bootloader.

This patch implements a handler for common SiP calls. A weak
implementation for the SoC-specific handler has been provided
which can be overridden by SoCs to implement any custom SiP
calls.

The BL2 fills in the UART controller ID to be used as the normal as
well as the crash console on Tegra platforms. The controller ID to
UART controller base address mapping is handled by each Tegra SoC
the base addresses might change across Tegra chips.
This patch adds the handler to parse the platform params to get the
UART ID for the per-soc handlers.

This patch renames the current Memory Controller driver files to
"_v1". This is done to add a driver for the new Memory Controller
hardware (v2).

This patch enables the processor retention and L2/CPUECTLR read/write
access from the NS world only for Cortex-A57 CPUs on the Tegra SoCs.

This patch moves these address translation helper macros to individual
Tegra SoC makefiles to provide more control.

This patch converts the common SiP handler to SoC specific SiP
handler. T210 and T132 have different SiP SMCs and so it makes
sense to move the SiP handler to soc/t132 and soc/t210 folders.

The Flow Controller hardware block is not present across all Tegra
SoCs, hence include the driver files from SoC specific makefiles.
T132/T210 are the SoCs which include this hardware block while future
SoCs have removed it.

This patch programs the CPUECTLR_EL1 and L2ECTLR_EL1 registers,
so that the core waits for 512 generic timer CNTVALUEB ticks before
entering retention state, after executing a WFI instruction.
This functionality is configurable and can be enabled for platforms
by setting the newly defined 'ENABLE_L2_DYNAMIC_RETENTION' and
'ENABLE_CPU_DYNAMIC_RETENTION' flag.

This patch moves the inclusion of CPU code (A53, A57) to T210's
makefile. This way we can reduce code size for Tegra platforms by
including only the required CPU files.

A new config, ENABLE_NS_L2_CPUECTRL_RW_ACCESS, allows Tegra platforms to
enable read/write access to the L2 and CPUECTRL registers. T210 is the
only platform that needs to enable this config for now.

T210 is the latest chip in the Tegra family of SoCs from NVIDIA. It is an
ARM v8 dual-cluster (A57/A53) SoC, with any one of the clusters being active
at a given point in time.
This patch adds support to boot the Trusted Firmware on T210 SoCs. The patch
also adds support to boot secondary CPUs, enter/exit core power states for
all CPUs in the slow/fast clusters. The support to switch between clusters
is still not available in this patch and would be available later.
