On DynamIQ CPU FVPs, stats test cases are failing when
hardware-assisted coherency is enabled due to a corrupt
timestamp value. Investigation of the issue indicates that
on these models the timestamp value is stored in cache
instead of memory. This patch flushes the dcache when the
timestamp is stored to make sure it is stored in memory.

This change is part of the goal of enabling the port to be compatible
with multiple FPGA images.
BL31 behaves differently depending on whether or not the CPUs in the
system use cache coherency, and as a result any CPU libraries that are
compiled together must serve processors that are consistent in this
regard.
This compiles a different set of CPU libraries depending on whether or
not the HW_ASSISTED_COHERENCY is enabled at build-time to indicate the
CPUs support hardware-level support for cache coherency. This build
flag is used in the makefile in the same way as the Arm FVP port.

This allows the BL31 port to run with position-independent execution
enabled so that it can be ran from any address in the system.
This increases the flexibility of the image, allowing it to be ran from
other locations rather than only its hardcoded absolute address
(currently set to the typical DRAM base of 2GB). This may be useful for
future images that describe system configurations with other memory
layouts (e.g. where SRAM is included).
It does this by setting ENABLE_PIE=1 and changing the absolute
address to 0. The load address of bl31.bin can then be specified by
the -l [load address] argument in the fpga-run command (additionally,
this address is required by any preceding payloads that specify the
start address. For ELF payloads this is usually extracted automatically
by reading the entrypoint address in the header, however bl31.bin is a
different file format so has this additional dependency).

This change is part of the goal of enabling the port to be compatible
with multiple FPGA images.
The BL31 port that is uploaded as a payload to the FPGA with an image
should cater for a wide variety of system configurations. This patch
makes the necessary changes to enable it to function with images whose
cluster configurations may be larger (either by utilizing more
clusters, more CPUs per cluster, more threads in each CPU, or a
combination) than the initial image being used for testing.
As part of this, the hard-coded values that configure the size of the
array describing the topology of the power domain tree are increased
to max. 8 clusters, max. 8 cores per cluster & max 4 threads per core.
This ensures the port works with cluster configurations up to these
sizes. When there are too many entries for the number of available PEs,
e.g. if there is a variable number of CPUs between clusters, then there
will be empty entries in the array. This is permitted and the PSCI
library will still function as expected. While this increases its size,
this shouldn't be an issue in the context of the size of BL31, and is
worth the trade-off for the extra compatibility.

This adds a basic PSCI implementation allow secondary CPUs to be
released from an initial state and continue through to the warm boot
entrypoint.
Each secondary CPU is kept in a holding pen, whereby it polls the value
representing its hold state, by reading this from an array that acts as
a table for all the PEs. The hold states are initially set to 0 for all
cores to indicate that the executing core should continue polling.
To prevent the secondary CPUs from interfering with the platform's
initialization, they are only updated by the primary CPU once the cold
boot sequence has completed and fpga_pwr_domain_on(mpidr) is called.
The polling target CPU will then read 1 (which indicates that it should
branch to the warm reset entrypoint) and then jump to that address
rather than continue polling.
In addition to the initial polling behaviour of the secondary CPUs
before their warm boot reset sequence, they are also placed in a
low-power wfe() state at the end of each poll; accordingly, the PSCI
fpga_pwr_domain_on(mpidr) function also signals an event to all cores
(after updating the target CPU's hold entry) to wake them from this
state, allowing any secondary CPUs that are still polling to check
their hold state again.
This method is in accordance with both the PSCI and Linux kernel
recommendations, as the lessened overhead reduces the energy
consumption associated with the busy-loop.
The table of hold entries is implemented by a global array as shared SRAM
(which is used by other platforms in similar implementations) is not
available on the FPGA images.

This makes use of the PRELOADED_BL33_BASE flag to indicate to BL31 that
the BL33 payload (kernel) has already been loaded and resides in memory;
BL31 will then jump to the non-secure address.
For this port the BL33 payload is the Linux kernel, and in accordance
with the pre-kernel setup requirements (as specified in the `Booting
AArch64 Linux' documentation:
https://www.kernel.org/doc/Documentation/arm64/booting.txt),
this change also sets up the primary CPU's registers x0-x3 so they are
the expected values, which includes the address of the DTB at x0.
An external linker script is currently required to combine BL31, the
BL33 payload, and any other software images to create an ELF file that
can be uploaded to the FPGA board along with the bit file. It therefore
has dependencies on the value of PRELOADED_BL33_BASE (kernel base) and
the DTB base (plus any other relevant base addresses used to
distinguish the different ELF sections), both of which are set in this
patch.

This adds the minimal functions and definitions to create a basic
BL31 port for an initial FPGA image, in order for the port to be
uploaded to one the FPGA boards operated by an internal group within
Arm, such that BL31 runs as a payload for an image.
Future changes will enable the port for a wide range of system
configurations running on the FPGA boards to ensure compatibility with
multiple FPGA images.
It is expected that this will replace the FPGA fork of the Linux kernel
bootwrapper by performing similar secure-world initialization and setup
through the use of drivers and other well-established methods, before
passing control to the kernel, which will act as the BL33 payload and
run in EL2NS.
This change introduces a basic, loadable port with the console
initialized by setting the baud rate and base address of the UART as
configured by the Zeus image.
It is a BL31-only port, and RESET_TO_BL31 is enabled to reflect this.

once DDR access is setup. It is then unmapped and a new mapping DDR is done

The disabling of cache during DDR tests is also removed, as now useless.

different code path. The patch is marking a CPU as ON within
"cpu_powergate_mask" when turning its power domain on
