Using the fconf framework, the Group 0 and Group 1 secure interrupt
descriptors are moved to device tree and retrieved in runtime. This
feature is enabled by the build flag SEC_INT_DESC_IN_FCONF.

GICv3: GIC-600: Detect GIC-600 at runtime
...
The only difference between GIC-500 and GIC-600 relevant to TF-A is the
differing power management sequence.
A certain GIC implementation is detectable at runtime, for instance by
checking the IIDR register. Let's add that test before initiating the
GIC-600 specific sequence, so the code can be used on both GIC-600 and
GIC-500 chips alike, without deciding on a GIC chip at compile time.
This means that the GIC-500 "driver" is now redundant. To allow minimal
platform support, add a switch to disable GIC-600 support.

dualroot: add chain of trust for secure partitions
...
A new certificate "sip-sp-cert" has been added for Silicon Provider(SiP)
owned Secure Partitions(SP). A similar support for Platform owned SP can
be added in future. The certificate is also protected against anti-
rollback using the trusted Non-Volatile counter.
To avoid deviating from TBBR spec, support for SP CoT is only provided
in dualroot.
Secure Partition content certificate is assigned image ID 31 and SP
images follows after it.
The CoT for secure partition look like below.

plat/arm: do not include export header directly

As per "include/export/README", TF-A code should never include export
headers directly. Instead, it should include a wrapper header that
ensures the export header is included in the right manner.
"tbbr_img_def_exp.h" is directly included in TF-A code, this patch
replaces it with its wrapper header "tbbr_img_def.h".

This patch adds support for Total Compute (TC0) platform. It is an
initial port and additional features are expected to be added later.
TC0 has a SCP which brings the primary Cortex-A out of reset
which starts executing BL1. TF-A optionally authenticates the SCP
ram-fw available in FIP and makes it available for SCP to copy.
Some of the major features included and tested in this platform
port include TBBR, PSCI, MHUv2 and DVFS.

arm_fpga: Read UART address from DT
...
The arm_fpga port requires a DTB, to launch a BL33 payload.
To make this port more flexible, we can also use the information in the
DT to configure the console driver.
For a start, find the DT node pointed to by the stdout-path property, and
read the base address from there.
This assumes for now that the stdout-path points to a PL011 UART.
This allows to remove platform specific addresses from the image. We
keep the original base address for the crash console.

arm_fpga: Read GICD and GICR base addresses from DT

Since we use a DTB with all platform information to pass this on to a
kernel loaded as BL33, we can as well make use of it for our own
purposes.
Every DT would contain a node for the GIC(v3) interrupt controller, so
we can read the base address for the distributor and redistributors from
there.
This avoids hard coding this information in the code and allows for a more
flexible binary.

fdt/wrappers: Introduce code to find UART DT node
...
The stdout-path property in the /chosen node of a DTB points to a device
node, which is used for boot console output.
On most (if not all) ARM based platforms this is the debug UART.
The ST platform code contains a function to parse this property and
chase down eventual aliases to learn the node offset of this UART node.
Introduce a slightly more generalised version of this ST platform function
in the generic fdt_wrappers code. This will be useful for other platforms
as well.

arm_fpga: Read generic timer counter frequency from DT
...
The ARM Generic Timer DT binding describes an (optional) property to
declare the counter frequency. Its usage is normally discouraged, as the
value should be read from the CNTFRQ_EL0 system register.
However in our case we can use it to program this register in the first
place, which avoids us to hard code a counter frequency into the code.
We keep some default value in, if the DT lacks that property for
whatever reason.

fdt_get_reg_props_by_index() function, and move it to fdt_wrapper.c.
This is removes the assumption that #address-cells and #size-cells are
always one.

arm: fconf: Fix GICv3 dynamic configuration
...
At the moment the fconf_populate_gicv3_config() implementation is
somewhat incomplete: First it actually fails to store the retrieved
information (the local addr[] array is going nowhere), but also it makes
quite some assumptions about the device tree passed to it: it needs to
use two address-cells and two size-cells, and also requires all five
register regions to be specified, where actually only the first two
are mandatory according to the binding (and needed by our code).
Fix this by introducing a proper generic function to retrieve "reg"
property information from a DT node:
We retrieve the #address-cells and #size-cells properties from the
parent node, then use those to extract the right values from the "reg"
property. The function takes an index to select one region of a reg
property.
This is loosely based on the STM32 implementation using "reg-names",
which we will subsume in a follow-up patch.

fdt/wrappers: Replace fdtw_read_cells() implementation
...
Our fdtw_read_cells() implementation goes to great lengths to
sanity-check every parameter and result, but leaves a big hole open:
The size of the storage the value pointer points at needs to match the
number of cells given. This can't be easily checked at compile time,
since we lose the size information by using a void pointer.
Regardless the current usage of this function is somewhat wrong anyways,
since we use it on single-element, fixed-length properties only, for
which the DT binding specifies the size.
Typically we use those functions dealing with a number of cells in DT
context to deal with *dynamically* sized properties, which depend on
other properties (#size-cells, #clock-cells, ...), to specify the number
of cells needed.
Another problem with the current implementation is the use of
ambiguously sized types (uintptr_t, size_t) together with a certain
expectation about their size. In general there is no relation between
the length of a DT property and the bitness of the code that parses the
DTB: AArch64 code could encounter 32-bit addresses (where the physical
address space is limited to 4GB [1]), while AArch32 code could read
64-bit sized properties (/memory nodes on LPAE systems, [2]).
To make this more clear, fix the potential issues and also align more
with other DT users (Linux and U-Boot), introduce functions to explicitly
read uint32 and uint64 properties. As the other DT consumers, we do this
based on the generic "read array" function.
Convert all users to use either of those two new functions, and make
sure we never use a pointer to anything other than uint32_t or uint64_t
variables directly.
This reveals (and fixes) a bug in plat_spmd_manifest.c, where we write
4 bytes into a uint16_t variable (passed via a void pointer).
Also we change the implementation of the function to better align with
other libfdt users, by using the right types (fdt32_t) and common
variable names (*prop, prop_names).

fdt/wrappers: Generalise fdtw_read_array()
...
Currently our fdtw_read_array() implementation requires the length of
the property to exactly match the requested size, which makes it less
flexible for parsing generic device trees.
Also the name is slightly misleading, since we treat the cells of the
array as 32 bit unsigned integers, performing the endianess conversion.
To fix those issues and align the code more with other DT users (Linux
kernel or U-Boot), rename the function to "fdt_read_uint32_array", and
relax the length check to only check if the property covers at least the
number of cells we request.
This also changes the variable names to be more in-line with other DT
users, and switches to the proper data types.
This makes this function more useful in later patches.
