The arm_fpga platform code contains an dubious line to initialise some

plat/arm/board/arm_fpga: Compile with additional CPU libraries

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.

plat/arm/board/arm_fpga: Enable position-independent execution

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).

plat/arm/board/arm_fpga: Enable port for alternative cluster configurations

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.
