From the hotplug testing on Hikey960, in some case cores fail to become
online in the system. When some cores are hotplugged off, if other
cores in the same cluster enter into CPU idle states at the meantime,
the cluster will be powered off. This introduces the state machine
malfunction in the power controller, thus when hotplug on the core
afterwards, it fails to boot up the core because the power controller
thinks the cluster is powered on.

This patch is to avoid race condition between hotplug and idles by
preventing cluster power off when some of cores in the cluster are
hotplugged off, if all cores in the same cluster are hotplugged off,
the cluster can be powered off.

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.
