The code to check for the presence of the TRNG service relies on
toolchain garbage collection, which is not enabled with -O0.

Add #ifdef guards around the call to the TRNG service handler to
cover builds without optimisation as well.

* changes:
  plat/arm: fvp: Protect GICR frames for fused/unused cores
  doc: Build option to protect GICR frame
  plat/arm: fvp: Do not map GIC region in BL1 and BL2

Currently, BLs are mapping the GIC memory region as read-write
for all cores on boot-up.

This opens up the security hole where the active core can write
the GICR frame of fused/inactive core. To avoid this issue, disable
the GICR frame of all inactive cores as below:

1. After primary CPU boots up, map GICR region of all cores as
   read-only.
2. After primary CPU boots up, map its GICR region as read-write
   and initialize its redistributor interface.
3. After secondary CPU boots up, map its GICR region as read-write
   and initialize its redistributor interface.
4. All unused/fused core's redistributor regions remain read-only and
   write attempt to such protected regions results in an exception.

As mentioned above, this patch offers only the GICR memory-mapped
region protection considering there is no facility at the GIC IP
level to avoid writing the redistributor area.

These changes are currently done in BL31 of Arm FVP and guarded under
the flag 'FVP_GICR_REGION_PROTECTION'.

As of now, this patch is tested manually as below:
1. Disable the FVP cores (core 1, 2, 3) with core 0 as an active core.
2. Verify data abort triggered by manually updating the ‘GICR_CTLR’
   register of core 1’s(fused) redistributor from core 0(active).

GIC memory region is not getting used in BL1 and BL2.
Hence avoid its mapping in BL1 and BL2 that freed some
page table entries to map other memory regions in the
future.

Retains mapping of CCN interconnect region in BL1 and BL2
overlapped with the GIC memory region.

This adds the TRNG Firmware Interface Service to the standard
service dispatcher. This includes a method for dispatching entropy
requests to platforms and includes an entropy pool implementation to
avoid dropping any entropy requested from the platform.

The coding guidelines[1] in TF-A forbid the use of ato*() functions
in favour of strto*(). However, the TF-A libc does not provide an
implementation of strto*(), making this rule impossible to satisfy.

Also made small changes to fit into TF-A project. Added the source
files to the libc makefile
