Migrate FVP port to use common code

Major update to the FVP platform port to use the common platform code
in (include/)plat/arm/* and (include/)plat/common/*. This mainly
consists of removing duplicated code but also introduces some small
behavioural changes where there was unnecessary variation between the
FVP and Juno ports. See earlier commit titled `Add common ARM and CSS
platform code` for details.

Also add support for Foundation FVP version 9.1 during FVP config
setup to prevent a warning being emitted in the console.

Add common ARM and CSS platform code

This major change pulls out the common functionality from the
FVP and Juno platform ports into the following categories:

* (include/)plat/common. Common platform porting functionality that
typically may be used by all platforms.

* (include/)plat/arm/common. Common platform porting functionality
that may be used by all ARM standard platforms. This includes all
ARM development platforms like FVP and Juno but may also include
non-ARM-owned platforms.

* (include/)plat/arm/board/common. Common platform porting
functionality for ARM development platforms at the board
(off SoC) level.

* (include/)plat/arm/css/common. Common platform porting
functionality at the ARM Compute SubSystem (CSS) level. Juno
is an example of a CSS-based platform.

* (include/)plat/arm/soc/common. Common platform porting
functionality at the ARM SoC level, which is not already defined
at the ARM CSS level.

No guarantees are made about the backward compatibility of
functionality provided in (include/)plat/arm.

Also remove any unnecessary variation between the ARM development
platform ports, including:

* Unify the way BL2 passes `bl31_params_t` to BL3-1. Use the
Juno implementation, which copies the information from BL2 memory
instead of expecting it to persist in shared memory.

* Unify the TZC configuration. There is no need to add a region
for SCP in Juno; it's enough to simply not allow any access to
this reserved region. Also set region 0 to provide no access by
default instead of assuming this is the case.

* Unify the number of memory map regions required for ARM
development platforms, although the actual ranges mapped for each
platform may be different. For the FVP port, this reduces the
mapped peripheral address space.

These latter changes will only be observed when the platform ports
are migrated to use the new common platform code in subsequent
patches.

Allow deeper platform port directory structure

Update the top level makefile to allow platform ports to exist in
subdirectories at any level instead of one level under `plat/`. The
makefile recursively searches for all files called `platform.mk` in
all subdirectories of `plat/`. The directory containing
`platform.mk` is the platform name. Platform names must be unique
across the codebase.

Replace usage of HELP_PLATFORMS in the Makefile with PLATFORMS since
these are both used to report the same information back to the user.

Update the TSP and cert_create tool makefiles in a similar way
to support a deeper platform port directory structure.

Also add PLAT_<plat_name> as a define passed through the top level
makefile to the source files, to allow build time variation in common
platform code.

Remove use of PLATFORM_CACHE_LINE_SIZE

The required platform constant PLATFORM_CACHE_LINE_SIZE is
unnecessary since CACHE_WRITEBACK_GRANULE effectively provides the

is an architecturally defined term and allows comparison with the
corresponding hardware register value.

Replace all usage of PLATFORM_CACHE_LINE_SIZE with
CACHE_WRITEBACK_GRANULE.

Also, add a runtime assert in BL1 to check that the provided
CACHE_WRITEBACK_GRANULE matches the value provided in CTR_EL0.

Fix recursive crash prints on FVP AEM model

This patch fixes an issue in the cpu specific register reporting
of FVP AEM model whereby crash reporting itself triggers an exception
thus resulting in recursive crash prints. The input to the
'size_controlled_print' in the crash reporting framework should
be a NULL terminated string. As there were no cpu specific register
to be reported on FVP AEM model, the issue was caused by passing 0
instead of NULL terminated string to the above mentioned function.

Pass arguments/results between EL3/S-EL1 via CPU registers (x0-x7)

This patch removes the need for a shared buffer between the EL3 and S-EL1
levels. We now use the CPU registers, x0-x7, while passing data between
the two levels. Since TLK is a 32-bit Trusted OS, tlkd has to unpack the
arguments in the x0-x7 registers. TLK in turn gets these values via r0-r7.

The return value of bl2_plat_handle_bl30() used to be ignored.
This patch modifies the function load_bl30() so that it now

This patch also unifies the error handling code across the
load_blx() functions so that they return a status code in all
cases and bl2_main() has the sole responsibility of panicking
if appropriate.

Add support to indicate size and end of assembly functions

In order for the symbol table in the ELF file to contain the size of
functions written in assembly, it is necessary to report it to the
assembler using the .size directive.

To fulfil the above requirements, this patch introduces an 'endfunc'
macro which contains the .endfunc and .size directives. It also adds
a .func directive to the 'func' assembler macro.

The .func/.endfunc have been used so the assembler can fail if
endfunc is omitted.
