Support booting OP-TEE as BL32 boot stage and secure runtime
service.

OP-TEE executes in internal RAM and uses a secure DDR area to store
the pager pagestore. Memory mapping and TZC are configured accordingly
prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
a header file describes the effective boot images. This change
post processes header file content to get OP-TEE load addresses
and set OP-TEE boot arguments.

The i.MX8M Mini is new SOC of the i.MX8M family. it is
focused on delivering the latest and greatest video and
audio experience combining state-of-the-art media-specific
features with high-performance processing while optimized
for lowest power consumption. The i.MX 8M Mini Media Applications
Processor is  14nm FinFET product of the growing i.MX8M family
targeting the consumer & industrial market. It is built in 14LPP
to achieve both high performance and low power consumption
and relies on a powerful fully coherent core complex based on
a quad Cortex-A53 cluster with video and graphics accelerators

This patch provides support for using the scatterfile format as
the linker script with the 'armlink' linker for Tegra platforms.

In order to enable the scatterfile usage the following changes
have been made:

* provide mapping for ld.S symbols in bl_common.h
* include bl_common.h from all the affected files
* update the makefile rules to use the scatterfile and armlink
  to compile BL31
* update pubsub.h to add sections to the scatterfile

NOTE: THIS CHANGE HAS BEEN VERIFIED WITH TEGRA PLATFORMS ONLY.

The non secure world would like to profile the boot path for
the EL3 and S-EL1 firmwares. To allow it to do that, a non-secure
DRAM region (4K) is allocated and the base address is passed to
the EL3 firmware.

This patch adds a library to allow the platform code to store the
tag:timestamp pair to the shared memory. The tegra platform code
then uses the `record` method to add timestamps.

d4fd0219 (pull request #1685) introduced unwanted formatting
such as bold/italic in the description for RPI3_USE_UEFI_MAP.

The default Raspberry Pi 3 memory mapping for ATF is geared towards
the use of uboot + Linux. This creates issues when trying to use
ATF with an UEFI payload and Windows on ARM64.

We therefore introduce new build option RPI3_USE_UEFI_MAP, that
enables the build process to use an alternate memory mapping that
is compatible with UEFI + Windows (as well as UEFI + Linux).

Some OSes (e.g. Ubuntu 18.04 LTS on Raspberry Pi 3) may disable the
runtime UART in a manner that prevents the system from rebooting if
ATF tries to send runtime messages there.

Also, we don't want the firmware to share the UART with normal
world, as this can be a DoS attack vector into the secure world.

This patch fixes these 2 issues by introducing new build option
RPI3_RUNTIME_UART, that disables the runtime UART by default.

When a device tree blob is present at a known address, instead of, for
example, relying on the user modifying the Linux command line to warn
about the memory reserved for the Trusted Firmware, pass it on the DTB.

The current code deletes the memory reserved for the default bootstrap
of the Raspberry Pi and adds the region used by the Trusted Firmware.

This system replaces the previous one consisting on adding
``memmap=16M$256M`` to the Linux command line. It's also meant to be
used by U-Boot and any other bootloader that understands DTB files.

Overview
---------

BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered
at this exception level (the Renesas' ATF reference tree [1] resets into
EL1 before entering BL2 - see its bl2.ld.S)

BL2 initializes DDR (and i2c to talk to the PMIC on some platforms)
before determining the boot reason (cold or warm).

During suspend all CPUs are switched off and the DDR is put in
backup mode (some kind of self-refresh mode). This means that BL2 is
always entered in a cold boot scenario.

Once BL2 boots, it determines the boot reason, writes it to shared
memory (BOOT_KIND_BASE) together with the BL31 parameters
(PARAMS_BASE) and jumps to BL31.

To all effects, BL31 is as if it is being entered in reset mode since
it still needs to initialize the rest of the cores; this is the reason
behind using direct shared memory access to  BOOT_KIND_BASE and
PARAMS_BASE instead of using registers to get to those locations (see
el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
case).

Depending on the boot reason BL31 initializes the rest of the cores:
in case of suspend, it uses a MBOX memory region to recover the
program counters.
