plat: imx: imx8qm: apply clk/pinmux configuration for DEBUG_CONSOLE ...

Having DEBUG_CONSOLE enabled without enabling DEBUG_CONSOLE_A53
doesn't make sense (since UART pinmux/clock configuration is applied
for UART only when DEBUG_CONSOLE_A53 is enabled).

Enable DEBUG_CONSOLE_A53 if DEBUG_CONSOLE is enabled.

plat: imx: imx8qm: provide debug uart num as build param ...

This removes hardcoded iomux/clk/addr configuration for debug uart,
provides possibility (as a workaround, till that information isn't
provided via DT) to set this configuration during compile time via
IMX_DEBUG_UART build flag.

Usage:
$ make PLAT=imx8qm IMX_DEBUG_UART=1 bl31

plat/arm/fvp: populate pwr domain descriptor dynamically ...

The motivation behind this patch and following patches is to extract
information about the platform in runtime rather than depending on
compile time macros such as FVP_CLUSTER_COUNT. This partially enables
us to use a single binary for a family of platforms which all have
similar hardware capabilities but differ in configurations.

we populate the data structure describing the power domain hierarchy
of the platform dynamically by querying the number of clusters and cpus
using fconf getter APIs. Compile time macro such as FVP_CLUSTER_COUNT
is still needed as it determines the size of related data structures.

Note that the cpu-map node in HW_CONFIG dts represents a logical
hierarchy of power domains of CPU. However, in reality, the power
domains may not have been physically built in such hierarchy.

Tegra: smmu: remove context save sequence ...

SMMU and MC registers are saved as part of the System Suspend sequence.
The register list includes some NS world SMMU registers that need to be
saved by NS world software instead. All that remains as a result are
the MC registers.

This patch moves code to MC file as a result and renames all the
variables and defines to use the MC prefix instead of SMMU. The
Tegra186 and Tegra194 platform ports are updated to provide the MC
context register list to the parent driver. The memory required for
context save is reduced due to removal of the SMMU registers.

Tegra194: add SE support to generate SHA256 of TZRAM ...

The BL3-1 firmware code is stored in TZSRAM on Tegra194 platforms. This
memory loses power when we enter System Suspend and so its contents are
stored to TZDRAM, before entry. This opens up an attack vector where the
TZDRAM contents might be tampered with when we are in the System Suspend
mode. To mitigate this attack the SE engine calculates the hash of entire
TZSRAM and stores it in PMC scratch, before we copy data to TZDRAM. The
WB0 code will validate the TZDRAM and match the hash with the one in PMC
scratch.

This patch adds driver for the SE engine, with APIs to calculate the hash
and store to PMC scratch registers.

fconf: Extract topology node properties from HW_CONFIG dtb ...

Create, register( and implicitly invoke) fconf_populate_topology()
function which extracts the topology related properties from dtb into
the newly created fconf based configuration structure 'soc_topology'.
Appropriate libfdt APIs are added to jmptbl.i file for use with USE_ROMLIB
build feature.

A new property which describes the power domain levels is added to the
HW_CONFIG device tree source files.

This patch also fixes a minor bug in the common device tree file
fvp-base-gicv3-psci-dynamiq-common.dtsi
As this file includes fvp-base-gicv3-psci-common.dtsi, it is necessary
to delete all previous cluster node definitons because DynamIQ based
models have upto 8 CPUs in each cluster. If not deleted, the final dts
would have an inaccurate description of SoC topology, i.e., cluster0
with 8 or more core nodes and cluster1 with 4 core nodes.

   related to GIC(interrupt-controller node)

fconf: enhancements to firmware configuration framework ...

A populate() function essentially captures the value of a property,
defined by a platform, into a fconf related c structure. Such a
callback is usually platform specific and is associated to a specific
configuration source.
For example, a populate() function which captures the hardware topology
of the platform can only parse HW_CONFIG DTB. Hence each populator
function must be registered with a specific 'config_type' identifier.
It broadly represents a logical grouping of configuration properties
which is usually a device tree source file.

Example:
> TB_FW: properties related to trusted firmware such as IO policies,
	 base address of other DTBs, mbedtls heap info etc.
> HW_CONFIG: properties related to hardware configuration of the SoC
	 such as topology, GIC controller, PSCI hooks, CPU ID etc.

This patch modifies FCONF_REGISTER_POPULATOR macro and fconf_populate()
to register and invoke the appropriate callbacks selectively based on
configuration type.
