tbbr/dualroot: rename SP package certificate file
...
Currently only single signing domain is supported for SP packages but
there is plan to support dual signing domains if CoT is dualroot.
SP_CONTENT_CERT_ID is the certificate file which is currently generated
and signed with trusted world key which in-turn is derived from Silicon
provider RoT key.
To allow dual signing domain for SP packages, other certificate file
will be derived from Platform owned RoT key.
This patch renames "SP_CONTENT_CERT_ID" to "SIP_SP_CONTENT_CERT_ID" and
does other related changes.

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/fvp: Support performing SDEI platform setup in runtime
...
This patch introduces dynamic configuration for SDEI setup and is supported
when the new build flag SDEI_IN_FCONF is enabled. Instead of using C arrays
and processing the configuration at compile time, the config is moved to
dts files. It will be retrieved at runtime during SDEI init, using the fconf
layer.

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.

fconf: Clean Arm IO
...
Merge the previously introduced arm_fconf_io_storage into arm_io_storage. This
removes the duplicate io_policies and functions definition.
This patch:
- replace arm_io_storage.c with the content of arm_fconf_io_storage.c
- rename the USE_FCONF_BASED_IO option into ARM_IO_IN_DTB.
- use the ARM_IO_IN_DTB option to compile out io_policies moved in dtb.
- propagate DEFINES when parsing dts.
- use ARM_IO_IN_DTB to include or not uuid nodes in fw_config dtb.
- set the ARM_IO_IN_DTB to 0 by default for fvp. This ensure that the behavior
of fvp stays the same as it was before the introduction of fconf.

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.

SPMD: loading Secure Partition payloads
...
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.

This patch introduces a SP populator function which gets UUID and load
address from firmware config device tree and updates its C data
structure.
