Build: introduce per-BL CPPFLAGS and ASFLAGS

Currently, BL*_CFLAGS and BL*_LDFLAGS are supported.
For completion, this adds BL*_CPPFLAGS and BL*_ASFLAGS.
My main motivation is to pass -D<macro> to BL*_CPPFLAGS so that
the macro can be used from all source files.

Makefile: Add support to optionally encrypt BL31 and BL32
...
Following build flags have been added to support optional firmware
encryption:
- FW_ENC_STATUS: Top level firmware's encryption numeric flag, values:
0: Encryption is done with Secret Symmetric Key (SSK) which is
common for a class of devices.
1: Encryption is done with Binding Secret Symmetric Key (BSSK) which
is unique per device.
- ENC_KEY: A 32-byte (256-bit) symmetric key in hex string format. It
could be SSK or BSSK depending on FW_ENC_STATUS flag.
- ENC_NONCE: A 12-byte (96-bit) encryption nonce or Initialization Vector
(IV) in hex string format.
- ENCRYPT_BL31: Binary flag to enable encryption of BL31 firmware.
- ENCRYPT_BL32: Binary flag to enable encryption of Secure BL32 payload.
Similar flags can be added to encrypt other firmwares as well depending
on use-cases.

Build: support per-BL LDFLAGS
...
make_helpers/build_macros.mk supports per-BL CFLAGS. For example,
you can pass compiler flags only to BL31 by using BL31_CFLAGS.
This commit adds per-BL LDFLAGS support, which is useful as well.
My main motivation of this addition is to use it for ENABLE_PIE.
When ENABLE_PIE is enabled, some linker flags are added to TF_LDFLAGS,
which affects all the TF images. It will make more sense to pass the
relevant options only to BL images that support it.

Using the /include/ syntax, the include was evaluated by dtc, only after running

adds the #include syntax instead. Evaluating this and preprocessing the files

Enable Link Time Optimization in GCC
...
This patch enables LTO for TF-A when compiled with GCC.
LTO is disabled by default and is enabled by
ENABLE_LTO=1 build option.
LTO is enabled only for aarch64 as there seem to be
a bug in the aarch32 compiler when LTO is enabled.
The changes in the makefiles include:
- Adding -flto and associated flags to enable LTO.
- Using gcc as a wrapper at link time instead of ld.
This is recommended when using LTO as gcc internally
takes care of invoking the necessary plugins for LTO.
- Adding switches to pass options to ld.
- Adding a flag to disable fix for erratum cortex-a53-843419
unless explicitly enabled. This is needed because GCC
seem to automatically add the erratum fix when used
as a wrapper for LD.
Additionally, this patch updates the TF-A user guide with
the new build option.

Switch AARCH32/AARCH64 to __aarch64__
...
NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__.
All common C compilers pre-define the same macros to signal which
architecture the code is being compiled for: __arm__ for AArch32 (or
earlier versions) and __aarch64__ for AArch64. There's no need for TF-A
to define its own custom macros for this. In order to unify code with
the export headers (which use __aarch64__ to avoid another dependency),
let's deprecate the AARCH32 and AARCH64 macros and switch the code base
over to the pre-defined standard macro. (Since it is somewhat
unintuitive that __arm__ only means AArch32, let's standardize on only
using __aarch64__.)

build_macros: Add mechanism to prevent bin generation.
...
On certain platforms it does not make sense to generate
TF-A binary images. For example a platform could make use of serveral
memory areas, which are non-continuous and the resulting binary
therefore would suffer from the padding-bytes.
Typically these platforms use the ELF image.
This patch introduces a variable DISABLE_BIN_GENERATION, which
can be set to '1' in the platform makefile to prevent the binary
generation.

U-boot/Linux kernel.
1. Creating seperate CPPFLAGS for DT preprocessing so that compiler
options specific to it can be accommodated.
e.g: "-undef" compiler option avoids replacing "linux" string(used in
device trees) with "1" as "linux" is a pre-defined macro in gnu99
standard.
2. Replace CPP with PP for DT pre-processing, as CPP in U-boot/Linux is
exported as "${CROSS_COMPILE}gcc -E" while in TF-A it is exported as
"${CROSS_COMPILE}cpp".

Makefile: Support totally quiet output with -s
...
"-s" is a command line option to the make tool, to suppress normal output,
something to the effect of prepending every line with '@' in the Makefile.
However with our V={0|1} support, we now print the shortened command line
output in any case (even with V=1, in addition to the long line!).
Normally -s helps to not miss non-fatal warnings, which tend to scroll out
of the window easily.
Introduce a new Makefile variable ECHO, to control the shortened output.
We only set it in the (current default) V=0 case, and replace every
occurence of "@echo" with that variable.
When the user specifies "-s", we set ECHO to some magic string which
changes the output line into a comment, so the output is suppressed.
Beside suppressing every output for "-s", we also avoid the redundant
short output when compiling with V=1.
This changes the output to:
==========
$ make -s PLAT=.... bl31
Built build/.../release/bl31.bin
==========
$ make PLAT=.... bl31
...
CC lib/libc/strncmp.c
CC lib/libc/strnlen.c

==========
$ make V=1 PLAT=.... bl31
...

"-Iinclude" is also added to INCLUDES.
It allows inclusion of dt-bindings files either in dts files or drivers,

"-i fdts" is added to the DTC command line.
As the pre-processed files are in build directory, the DT source directory

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.
