xlat: Fix missing header file dependency

Add TBBR and FWU support for AArch32

Add note about SPDX identifiers in license.md

Simplify assert() to reduce memory usage

xlat_tables_arch.h uses the platform macro `PLAT_VIRT_ADDR_SPACE_SIZE`.
This macro is defined in xlat_tables_private.h only if the platform
still uses the deprecated `ADDR_SPACE_SIZE`.

Juno: Fix AArch32 sp_min build

The commit abd2aba9

 introduced a
regression to the AArch32 sp_min Juno build. This patch fixes that.

rockchip: rk3328: Add assert check in pmu.c

mbedtls: Namespace update for TF specific macros

Break circular dependency in FVP and Nvidia header files

The behaviour of assert() now depends on the value of the new optional
platform define `PLAT_LOG_LEVEL_ASSERT`. This defaults to `LOG_LEVEL` if
not defined by the platform.

- If `PLAT_LOG_LEVEL_ASSERT` >= `LOG_LEVEL_VERBOSE`, it prints the file
  name, line and asserted expression.
- If `PLAT_LOG_LEVEL_ASSERT` >= `LOG_LEVEL_INFO`, it prints the file
  name and line.
- If not, it doesn't print anything.

Note the old behaviour was to print the function name whereas now it
prints the file name. This reduces memory usage because the file name is
shared between all assert calls in a given file. Also, the default
behaviour in debug builds is to no longer print the asserted expression,
greatly reducing the string usage.

For FVP debug builds this change saves approximately:

No need for these wrapper functions anymore.  The compiler-rt builtins

Add support for firmware upgrade on AArch32.
This patch has been tested on the FVP models.

This patch adds `TRUSTED_BOARD_BOOT` support for AArch32 mode.

To build this patch the "mbedtls/include/mbedtls/bignum.h"
needs to be modified to remove `#define MBEDTLS_HAVE_UDBL`
when `MBEDTLS_HAVE_INT32` is defined. This is a workaround
for "https://github.com/ARMmbed/mbedtls/issues/708

"

NOTE: TBBR support on Juno AArch32 is not currently supported.

Minor fixes to the xlat tables lib v2

A previous patch superseded the MBEDTLS_KEY_ALG. This patch updates
the ARM platforms to use the new TF_MBEDTLS_KEY_ALG define.

This patch renames MBEDTLS_KEY_ALG to TF_MBEDTLS_KEY_ALG. This
completes the migration of TF specific macros so that they do not
have the MBEDTLS_ suffix (see arm-trusted-firmware#874).

An earlier patch (arm-trusted-firmware#874) migrated MBEDTLS_ suffixed
macros to have a TBBR_ suffix to avoid any potential clash with future
mbedtls macros.

But on reflection the TBBR_ suffix could be confusing as the macros
are used to drive TF-specific configuration of mbedtls. As such
this patch migrates these macros from TBBR_suffix to TF_MBEDTLS_
suffix which more accurately conveys their use.

The current SMC context data structure `smc_ctx_t` and related helpers are
optimized for case when SMC call does not result in world switch. This was
the case for SP_MIN and BL1 cold boot flow. But the firmware update usecase
requires world switch as a result of SMC and the current SMC context helpers
were not helping very much in this regard. Therefore this patch does the
following changes to improve this:

1. Add monitor stack pointer, `spmon` to `smc_ctx_t`

The C Runtime stack pointer in monitor mode, `sp_mon` is added to the
SMC context, and the `smc_ctx_t` pointer is cached in `sp_mon` prior
to exit from Monitor mode. This makes is easier to retrieve the
context when the next SMC call happens. As a result of this change,
the SMC context helpers no longer depend on the stack to save and
restore the register.

This aligns it with the context save and restore mechanism in AArch64.

2. Add SCR in `smc_ctx_t`

Adding the SCR register to `smc_ctx_t` makes it easier to manage this
register state when switching between non secure and secure world as a
result of an SMC call.

This patch enables compiler-rt for the AArch32 target.  The code is
not used for AArch64 as the architecture supports the 64-bit division
and modulo operations natively.

Minor makefile fixes

Migrate secure payload dispatchers to new SMC terminology

AEMv8-A Model release v8.4 has been made available and Trusted Firmware
has been tested against these versions as part of its CI system. This
patch updates the user guide documentation to reflect the version of AEM
and Cortex Models that Trusted Firmware has been tested against.

Additionally, ARM FVPs FVP_Base_Cortex-A57x1-A53x1 and
FVP_Base_Cortex-A57x2-A53x4 are removed from the list of tested FVPs
as they are currently not being tested with the latest version of ARM
Trusted Firmware.

Also, documentation and links to Linaro pages have been updated to
reflect the changes in the ARM community document hosting.
