On Cortex-A7 an L2 set/way cache maintenance operation can overtake
an L1 set/way cache maintenance operation. The mitigation for this is
to use a `DSB` instruction before changing cache. The cache cleaning
code happens to already be doing this, so only a comment was added.

The spm_sp_get_by_uuid() function is used to look up the secure
partition that provides a given service.

Within this function, memcmp() is used to compare the service
UUIDs but it uses the size of the rdsvc->uuid pointer instead of
the size of its content (missing dereference). This means that only
a partial comparison is performed as UUIDs are 128 bits in length and
rdsvc->uuid is a uint32_t typed pointer.

Instead, use the size of the array pointed to by the svc_uuid parameter,
which will be the full 128 bits, for the comparison.

The data structures in the auth-framework were changed by the previous
patch, and need to be updated.

This changes the auth_img_desc_t struct to have pointers to struct
arrays instead of struct arrays. This saves memory as many of these
were never used, and can be NULL pointers. Note the memory savings are
only when these arrays are not initialised, as it is assumed these
arrays are fixed length. A possible future optimisation could allow for
variable length.

When Trusted Board Boot is enabled, we need to specify the Chain of
Trust (CoT) of the BL1 and BL2 images. A CoT consists of an array
of image descriptors. The authentication module assumes that each
image descriptor in this array is indexed by its unique image
identifier. For example, the Trusted Boot Firmware Certificate has to
be at index [TRUSTED_BOOT_FW_CERT_ID].

Unique image identifiers may not necessarily be consecutive. Also,
a given BL image might not use all image descriptors. For example, BL1
does not need any of the descriptors related to BL31. As a result, the
CoT array might contain holes, which unnecessarily takes up space in
the BL binary.

Using pointers to auth_img_desc_t structs (rather than structs
themselves) means these unused elements only use 1 pointer worth of
space, rather than one struct worth of space. This patch also changes
the code which accesses this array to reflect the change to pointers.

Image descriptors not needed in BL1 or BL2 respectively are also
ifdef'd out in this patch. For example, verifying the BL31 image is
the responsibility of BL2 so BL1 does not need any of the data
structures describing BL31.

ARMv7 and Cortex-A32(ARMv8/aarch32) uses "arm-linux-gnueabi" toolchain which
has both soft-float and hard-float variants and so there could be scenarios
where soft-float toolchain is used.Even though TF-A documentation recommends
to use hard-float toolchain for aarch32 but there are external projects where
we cannot mandate the selection of toolchain and for those projects at least
the build should not fail.

Current TF-A source fails to build with soft-float toolchain because assembler
does not recognizes "vmsr" instruction which is required to enable floating
point unit.

To avoid this piece of code being compiled with soft-float toolchain add
predefined macro guard " __SOFTFP__" exposed by soft-float toolchain.

The change-log.rst file does not use the same symbols
as the other documents when organising its headings,
sub-headings and so on. In order to compile these
documents together with Sphinx, forming a top-level
index and a consistent structure, it is necessary to
normalise these.

rcar_gen3: plat: Add R-Car V3M support

SPM: Some improvements to xlat handling code

doc: Update contribution guidelines

Add support for Amlogic s905x (GXL)

Rather than using a fixed virtual address space size, read all regions
in the resource description of each partition and restrict the virtual
address space size to the one the partition actually needs.

This also allows SPM to take advantage of the extension ARMv8.4-TTST if
the virtual address space size is small enough.

Right now the virtual address space is fixed to
PLAT_VIRT_ADDR_SPACE_SIZE, so all base translation tables are the same
size and need the same alignment. The current code allocates the exact
space needed by this initial table.

However, a following patch is going to allow each partition to choose
the size of its address space based on the memory regions defined in
their resource description, so it isn't possible to determine this at
build time. As this optimization no longer applies, it has to be
removed.

This gives each Secure Partition complete freedom on its address space.
Previously, the memory used by the exception vectors was reserved and
couldn't be used. Also, it always had to be mapped, forcing SPM to
generate translation tables that included the exception vectors as well
as the Partition memory regions. With this change, partitions can reduce
their address space size easily.

On Amlogic gxl (s905x) SOC, in order to use SCP, bl31 has to send bl30
and bl301 firmware along with their SHA256 hash over scpi.
Signed-off-by: Remi Pommarel <repk@triplefau.lt>

In order to configure and boot SCP, BL31 has to compute and send
the SHA-256 of the firmware data via scpi. Luckily Amlogic GXL SOC
has a DMA facility that could be used to offload SHA-256
computations. This adds basic support of this hardware SHA-256
engine.

The Amlogic Meson S905x is a SoC with a quad core Arm Cortex-A53 running
at 1.5Ghz. It also contains a Cortex-M3 used as SCP.

This port is a minimal implementation of BL31 capable of booting
mainline U-Boot and Linux:

- Partial SCPI support.
- Basic PSCI support (CPU_ON, SYSTEM_RESET, SYSTEM_OFF).
- GICv2 driver set up.
- Basic SIP services (read efuse data, enable/disable JTAG).

This port has been tested on a lepotato.
