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.

Necessary infrastructure added to integrate fconf framework in BL31 & SP_MIN.
Created few populator() functions which parse HW_CONFIG device tree
and registered them with fconf framework. Many of the changes are
only applicable for fvp platform.
This patch:
1. Adds necessary symbols and sections in BL31, SP_MIN linker script
2. Adds necessary memory map entry for translation in BL31, SP_MIN
3. Creates an abstraction layer for hardware configuration based on
fconf framework
4. Adds necessary changes to build flow (makefiles)
5. Minimal callback to read hw_config dtb for capturing properties
related to GIC(interrupt-controller node)
6. updates the fconf documentation

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.

The BL3-1 firmware code is stored in TZSRAM on Tegra186 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 SE SHA256 hash-result to PMC scratch registers.

As bpmp-fw is running at the same time as ATF, and
the mss client reconfiguration sequence involves performing
a hot flush resets on bpmp, there is a chance that bpmp-fw is
trying to perform accesses while the hot flush is active.
Therefore, the mss client reconfigure has been moved to
System Suspend resume fw and bootloader, and it can be
removed from here.

Currently, the ROM region is needlessly too large.

requirement: R060_TBBR_FUNCTION). So add an IO abstaction layer to
support firmware decryption that can be stacked above any underlying IO/
packaging layer like FIP etc. It aims to provide a framework to load any
encrypted IO payload.
Also, add plat_get_enc_key_info() to be implemented in a platform

Since commit ac71344e9e we have the UART base address in the generic
console_t structure. For most platforms the platform-specific struct
console is gone, so we *must* use the embedded base address, since there
is no storage behind the generic console_t anymore.
Replace the usage of CONSOLE_T_DRVDATA with CONSOLE_T_BASE to fix this.

Commit ac71344e9e moved the base address
for the MMIO aperture of the console inside the console_t struct. As
a result, the driver should now save the MMIO base address to console_t
at offset marked by the CONSOLE_T_BASE macro.
This patch updates the SPE console driver to use the CONSOLE_T_BASE macro
to save/access the MMIO base address.

This patch implements loading of Secure Partition packages using
existing framework of loading other bl images.
The current framework uses a statically defined array to store all the
possible image types and at run time generates a link list and traverse
through it to load different images.
To load SPs, a new array of fixed size is introduced which will be
dynamically populated based on number of SPs available in the system
and it will be appended to the loadable images list.

The revision register address will be changed in the next SoC.
The LSI revision is needed in order to know where the revision
register is located, but you need to read out the revision
register for that. This is impossible.
We need to know the revision register address by other means.
Use BL_CODE_BASE, where the base address of the TF image that is
currently running. If it is bigger than 0x80000000 (i.e. the DRAM
base is 0x80000000), we assume it is a legacy SoC.
