Currently the `tzc400_configure_region` and `tzc_dmc500_configure_region`
functions uses uintptr_t as the data type for `region_top` and `region_base`
variables, which will be converted to 32/64 bits for AArch32/AArch64
respectively. But the expectation is to keep these addresses at least 64 bit.
This patch modifies the data types to make it at least 64 bit by using
unsigned long long instead of uintptr_t for the `region_top` and
`region_base` variables. It also modifies the associated macros
`_tzc##fn_name##_write_region_xxx` accordingly.

To avoid confusion the build option BL33_BASE has been renamed to
PRELOADED_BL33_BASE, which is more descriptive of what it does and
doesn't get mistaken by similar names like BL32_BASE that work in a
completely different way.
NOTE: PLATFORMS USING BUILD OPTION `BL33_BASE` MUST CHANGE TO THE NEW
BUILD OPTION `PRELOADED_BL33_BASE`.

The BL33 address is now set in arm_bl31_early_platform_setup() so
that the preloaded BL33 boot option is available when RESET_TO_BL31
is also used.

Previously, when building TF without SPD support, BL2 tried to load a
BL32 image from the FIP and fails to find one, which resulted on
warning messages on the console. Even if there is a BL32 image in the
FIP it shouldn't be loaded because there is no way to transfer
control to the Secure Payload without SPD support.
The Makefile has been modified to pass a define of the form
SPD_${SPD} to the source code the same way it's done for PLAT. The
define SPD_none is then used to undefine BL32_BASE when BL32 is not
used to prevent BL2 from trying to load a BL32 image and failing,
thus removing the warning messages mentioned above.

This patch adds support to differentiate between `long` and `long long`
format specifiers in tf_printf(). In AArch64, they are the same which is
a 64-bit word. But, in AArch32 they are different and tf_printf() needs
to handle these format specifiers separately. This patch also fixes the
type of variables used to generic C types.

This patch enables the SCR_EL3.SIF (Secure Instruction Fetch) bit in BL1 and
BL31 common architectural setup code. When in secure state, this disables
instruction fetches from Non-secure memory.
NOTE: THIS COULD BREAK PLATFORMS THAT HAVE SECURE WORLD CODE EXECUTING FROM
NON-SECURE MEMORY, BUT THIS IS CONSIDERED UNLIKELY AND IS A SERIOUS SECURITY
RISK.

This patch adds support for image unpacking to the FIP packaging
tool. Command line option '-u,--unpack' may be used to unpack the
contents of an existing FIP file into the working directory. The
tool uses default hardcoded filenames for the unpacked images. If
the files already exist, they can be overwritten by specifying the
option '-f,--force'.

To get round problems encountered when building in a DOS build
environment the generation of the .o file containing build identifier
strings is modified.
The problems encounterred were:
1. DOS echo doesn't strip ' characters from the output text.
2. git is not available from CMD.EXE so the BUILD_STRING value needs
some other origin.
A BUILD_STRING value of "development build" is used for now.
MAKE_BUILD_STRINGS is used to customise build string generation in a DOS
environment. This variable is not defined in the UNIX build environment
make file helper, and so the existing build string generation behaviour
is retained in these build environments.
NOTE: This commit completes a cumulative series aimed at improving
build portability across development environments.
This enables the build to run on several new build environments,
if the relevant tools are available.
At this point the build is tested on Windows 7 Enterprise SP1,
using CMD.EXE, Cygwin and Msys (MinGW),as well as a native
Linux envionment". The Windows platform builds used
aarch64-none-elf-gcc.exe 4.9.1. CMD.EXE and Msys used Gnu
Make 3.81, cygwin used Gnu Make 4.1.
CAVEAT: The cert_create tool build is not tested on the Windows
platforms (openssl-for-windows has a GPL license).

Because of command differences in some build environments the "inline"
method of generating the build directory structure is not portable.
(e.g. in DOS environments the mkdir shell command fails if a directory
already exists, whereas in UNIX environments it succeeds.)
To improve portability we generate the directories needed using make,
but use the "order-only prerequisites" feature of make to prevent writes
of files into the directories generating re-builds, as suggested in the
GNU make Manual (Version 4.1 September 2014).

In some build environments executable programs have a specific file
extension. The value of BIN_EXT is appended to the relevant tool file
names to allow for this.
The value of BIN_EXT is set, where appropriate, by the build environment
specific make helper (to .exe for Windows build environments).
.gitignore is updated to hide the new (.exe) files.

Replace some "recursively expanded" make variables with "simply
expanded" variables (i.e. replace = with :=). This has no functional
impact but is more consistent and theoretically more efficient.

Some build environments do not support symbolic links. This patch
removes the symlinks previously used to build fip_create and instead
copies the relevant header files.
The original motivation for using symlinks was to avoid Trusted Firmware
library headers conflicting with headers in the compiler standard
include path. Copying the header files instead has the same effect.
Like other build artefacts, the copied files are listed in .gitignore.
The distclean targets have also been updated to remove the copies.

Add make helper files to select the appropriate settings for the build
environment. Selection is made in make_helpers/build_env.mk, which
selects other files to include using generic build environment settings.
The Trusted Firmware Makefile and supporting tool Makefiles are updated
to include build_env.mk instead of unix.mk.
NOTE: This change does not fully enable builds in other build
environments. It facilitates this without compromising the
existing build environments.

Macros are inserted to replace direct invocations of commands that are
problematic on some build environments. (e.g. Some environments expect
\ in paths instead of /.)
The changes take into account mismatched command mappings across
environments.
The new helper file unix.mk retains existing makefile behaviour on unix
like build environments by providing the following macro definitions:
SHELL_COPY cp -f
SHELL_COPY_TREE cp -rf
SHELL_DELETE rm -f
SHELL_DELETE_ALL rm -rf
MAKE_PREREQ_DIR mkdir -p (As make target)
SHELL_REMOVE_DIR rm -rf

As an initial stage of making Trusted Firmware build environment more
portable, we remove most uses of the $(shell ) function and replace them
with more portable make function based solutions.
Note that the setting of BUILD_STRING still uses $(shell ) since it's
not possible to reimplement this as a make function. Avoiding invocation
of this on incompatible host platforms will be implemented separately.

This patch adds support to program TrustZone protection on ARM platforms that
implement a DMC-500. arm_dmc_500.c has been added which implements the
arm_dmc_tzc_setup() function. This function relies on constants related to TZC
programming that are exported by each platform to program TrustZone protection
using the DMC-500 TrustZone controller driver. This function should be called
from plat_arm_security_setup() which is implemented by each platform.

The ARM CoreLink DMC-500 Dynamic Memory Controller provides the
programmable address region control of a TrustZone Address Space
Controller. The access permissions can be defined for eight
separate address regions plus a background or default region.
This patch adds a DMC-500 driver to define address regions and
program their access permissions as per ARM 100131_0000_02_en
(r0p0) document.
Change-Id: I9d33120f9480d742bcf7937e4b876f9d40c727e6
TrustZone protection can be programmed by both memory and TrustZone
address space controllers like DMC-500 and TZC-400. These peripherals
share a similar programmer's view.
Furthermore, it is possible to have multiple instances of each type of
peripheral in a system resulting in multiple programmer's views.
For example, on the TZC-400 each of the 4 filter units can be enabled
or disabled for each region. There is a single set of registers to
program the region attributes. On the DMC-500, each filter unit has its
own programmer's view resulting in multiple sets of registers to program
the region attributes. The layout of the registers is almost the same
across all these variations.
Hence the existing driver in `tzc400\tzc400.c` is refactored into the
new driver in `tzc\tzc400.c`. The previous driver file is still maintained
for compatibility and it is now deprecated.

lib/aarch64/xlat_helpers.c defines helper functions to build
translation descriptors, but no common code or upstream platform
port uses them. As the rest of the xlat_tables code evolves, there
may be conflicts with these helpers, therefore this code should be
removed.
