Revert "Make all build results depend on all makefiles"
...
Seems to have unintended side-effects on the build system such as
rebuilding certain parts of TF even though nothing has changed.
This reverts commit c6f651f .

Build: add GZIP compression filter
...
One typical usage of the pre-tool image filter is data compression,
and GZIP is one of the most commonly used compression methods.
I guess this is generic enough to be put in the common script instead
of platform.mk.
If you want to use this, you can add something like follows to your
platform.mk:
BL32_PRE_TOOL_FILTER := GZIP
BL33_PRE_TOOL_FILTER := GZIP

Build: support pre-tool image processing
...
There are cases where we want to process images before they are
passed to cert_create / fiptool.
My main motivation is data compression. By compressing images, we can
save data storage, and possibly speed up loading images. The image
verification will also get faster because certificates are generated
based on compressed images.
Other image transformation filters (for ex. encryption), and their
combinations would be possible. So, our build system should support
transformation filters in a generic manner.
The choice of applied filters is up to platforms (so specified in
platform.mk)
To define a new filter, <FILTER_NAME>_RULE and <FILTER_NAME>_SUFFIX
are needed.
For example, the GZIP compression filter can be implemented as follows:
------------------------>8------------------------
define GZIP_RULE
$(1): $(2)
@echo " GZIP $$@"
$(Q)gzip -n -f -9 $$< --stdout > $$@
endef
GZIP_SUFFIX := .gz
------------------------>8------------------------
The _RULE defines how to create the target $(1) from the source $(2).
The _SUFFIX defines the extension appended to the processed image path.
The suffix is not so important because the file name information is not
propagated to FIP, but adding a sensible suffix will be good to classify
the data file.
Platforms can specify which filter is applied to which BL image, like
this:
------------------------>8------------------------
BL32_PRE_TOOL_FILTER := GZIP
BL33_PRE_TOOL_FILTER := GZIP
------------------------>8------------------------
<IMAGE_NAME>_PRE_TOOL_FILTER specifies per-image filter. With this,
different images can be transformed differently. For the case above,
only BL32 and BL33 are GZIP-compressed. Nothing is done for other
images.

Build: change the first parameter of TOOL_ADD_IMG to lowercase
...
In the next commit, I need the image name in lowercase because
output files are generally named in lowercase.
Unfortunately, TOOL_ADD_IMG takes the first argument in uppercase
since we generally use uppercase Make variables.
make_helpers/build_macros.mk provides 'uppercase' macro to convert
a string into uppercase, but 'lowercase' does not exist. We can
implement it if we like, but it would be more straightforward to
change the argument of TOOL_ADD_IMG.

Build: move cert_create arguments and dependency to FIP_ADD_PAYLOAD
...
The fiptool and cert_create use the same command options for images.
It is pretty easy to handle both in the same, symmetrical way.
Move CRT_ARGS and CRT_DEPS to FIP_ADD_PAYLOAD. This refactoring makes
sense because FIP_ADD_PAYLOAD is called from MAKE_BL (when building
images from source), and from FIP_ADD_IMG (when including external
images). (FIP_ADD_PAYLOAD will be renamed later on since it now
caters to both fiptool and cert_create).
We can delete CERT_ADD_CMD_OPT for images in tbbr.mk. It still
needs to call CERT_ADD_CMD_OPT directly for certificates.

Build: merge build macros between FIP_ and FWU_FIP_
...
The build system supports generating two FIP images, fip and fwu_fip.
Accordingly, we have similar build macros.
FIP_ADD_PAYLOAD <--> FWU_FIP_ADD_PAYLOAD
CERT_ADD_CMD_OPT <--> FWU_CERT_ADD_CMD_OPT
FIP_ADD_IMG <--> FWU_FIP_ADD_IMG
The duplicated code increases the maintenance burden. Also, the build
rule of BL2U looks clumsy - we want to call MAKE_BL to compile it from
source files, but we want to put it in fwu_fip. We can not do it in a
single macro call since the current MAKE_BL does not support fwu_fip.
To refactor those in a clean way is to support one more argument to
specify the FIP prefix. If it is empty, the images are targeted to
fip, whereas if the argument is "FWU_", targeted to fwu_fip.
The build macros prefixed with FWU_ go away.

Makefile: Add ability to build dtb
...
This is a revamp of the original approach in:
https://github.com/ARM-software/arm-trusted-firmware/pull/747
Current build system has no means to automatically generate dtbs from
dts, instead, stores the dtbs in the fdts/ folder. While this makes
perfect sense for many reference platforms, this becomes a minor
breakage in development flow for newer platforms.
However, this can be solved by providing a rule for the dtbs while
building the ATF binaries by purely describing which dts sources we
need.
For example, with this change, we will now be able to describe the
dtbs we need for the platform in the corresponding platform.mk file:
FDT_SOURCES += fdts/abc.dts
This should be able to generate the abc.dtb appropriately.
Since device trees are specification of hardware, we don't tie the rule
to any specific BL, instead a generic rule is introduced.
Further, this approach allows us to generate appropriate dtbs which may be
need to be regenerated when a common dtsi gets updated, by just
restricting changes to the dtsi alone, instead of synchronizing all the
dtbs as well.
If dtc is not available in default paths, but is available in an
alternate location, it can be chosen by overriding the DTC variable
such as 'make DTC=~/dtc/dtc ....`
NOTE: dtbs are built only with the explicit make dtbs command. The rule
is only available if the platform defines a FDT_SOURCES variable.

Build: Fix parallel build
...
2 problems were found, but are in one change to avoid submitting a patch
that might fail to build. The problems were:
1. The macro MAKE_PREREQ_DIR has a minor bug, in that it is capable of
generating recursive dependencies.
2. The inclusion of BUILD_DIR in TEMP_OBJ_DIRS left no explicit
dependency, BUILD_DIR might not exist when subdirectories are
created by a thread on another CPU.
This fix corrects these with the following changes:
1. MAKE_PREREQ_DIR does nothing for a direct self dependency.
2. BUILD_DIR is built using MAKE_PREREQ_DIR.
3. BUILD_DIR is an explicit prerequisite of all OBJ_DIRS.

Introduce locking primitives using CAS instruction
...
The ARMv8v.1 architecture extension has introduced support for far
atomics, which includes compare-and-swap. Compare and Swap instruction
is only available for AArch64.
Introduce build options to choose the architecture versions to target
ARM Trusted Firmware:
- ARM_ARCH_MAJOR: selects the major version of target ARM
Architecture. Default value is 8.
- ARM_ARCH_MINOR: selects the minor version of target ARM
Architecture. Default value is 0.
When:
(ARM_ARCH_MAJOR > 8) || ((ARM_ARCH_MAJOR == 8) && (ARM_ARCH_MINOR >= 1)),
for AArch64, Compare and Swap instruction is used to implement spin
locks. Otherwise, the implementation falls back to using
load-/store-exclusive instructions.
Update user guide, and introduce a section in Firmware Design guide to
summarize support for features introduced in ARMv8 Architecture
Extensions.

Build: Fix parallel building

Building fvp
make: *** No rule to make target 'build/fvp/release/bl1/',

make: *** Waiting for unfinished jobs....
The cause of the failure is that $(dir ) leaves a trailing / on the
directory names. It must be ripped off to let Make create the
directory.
There are some ways to fix the issue. Here, I chose to make MAKE_LD
look like MAKE_C and MAKE_S because bl*_dirs seems the central place
of making directories.
