FVP: Fix AArch32 dts for `interrupts` node
The commit
8d2c497 changed the interrupt map in `rtsm_ve-motherboard.dtsi`
for the Linux FDT sources to be compatible for FreeBSD. But this also
introduced a regression for FVP AArch32 mode but was undetected till now
because the corresponding DTB was not updated. This patch creates a
new `rtsm_ve-motherboard-aarch32.dtsi` which reverts the change and is
now included by the AArch32 DTS files.

ARM Platforms: Load HW_CONFIG in BL2
The patch adds the necessary changes to load HW_CONFIG in BL2 for
ARM Platforms :
1. The load address of HW_CONFIG is specified via the `hw_config_addr`
property in TB_FW_CONFIG is loaded by BL1. The `hw_config_max_size`
property defines the maximum size to be expected for the HW_CONFIG.
The `arm_dyn_cfg_helpers.c` and corresponding header implements
utility functions to parse these DT properties defined.
The `arm_dyn_cfg.c` implements wrappers to these helpers to enable
them to be invoked from ARM platform layer.
2. `HW_CONFIG` is added to the `bl2_mem_params_descs[]` array which is
the list of images to be loaded by BL2.
3. The `libfdt` sources are now included when BL2 is built
4. A new helper `populate_next_bl_params_config()` is introduced in
desc_image_load.c to populate the subsequent executable BL images
with the `hw_config` and the corresponding `fw_config` if available.
The `plat_get_next_bl_params()` API for ARM platforms is modified to
invoke this new helper.
5. The implementation of `bl2_early_platform_setup2()` is modified to
consider `arg0` as well in addition to `arg1` passed from BL1.
6. Bump up the BL2 size for Juno to accommodate the inclusion of libfdt.

The value wasn't sign-extended because it was defined as a 32-bit

SMC_PREEMPT has been redefined as -2 for the same reason.
NOTE: This might be a compatibility break for some AArch64 platforms
that don't follow the previous version of the SMCCC (ARM DEN0028A)

TSPD: Require NS preemption along with EL3 exception handling
At present, the build option TSP_NS_INTR_ASYNC_PREEMPT controls how
Non-secure interrupt affects TSPs execution. When TSP is executing:
1. When TSP_NS_INTR_ASYNC_PREEMPT=0, Non-secure interrupts are received
at the TSP's exception vector, and TSP voluntarily preempts itself.
2. When TSP_NS_INTR_ASYNC_PREEMPT=1, Non-secure interrupts causes a
trap to EL3, which preempts TSP execution.
When EL3 exception handling is in place (i.e.,
EL3_EXCEPTION_HANDLING=1), FIQs are always trapped to EL3. On a system
with GICv3, pending NS interrupts while TSP is executing will be
signalled as FIQ (which traps to EL3). This situation necessitates the
same treatment applied to case (2) above.
Therefore, when EL3 exception handling is in place, additionally
require that TSP_NS_INTR_ASYNC_PREEMPT is set to one 1.
Strictly speaking, this is not required on a system with GICv2, but the
same model is uniformly followed regardless, for simplicity.
Relevant documentation updated.

zlib: add gunzip() support
This commit adds some more files to use zlib from TF.
To use zlib, ->zalloc and ->zfree hooks are needed. The implementation
depends on the system. For user-space, the libc provides malloc() and
friends. Unfortunately, ARM Trusted Firmware does not provide malloc()
or any concept of dynamic memory allocation.
I implemented very simple calloc() and free() for this. Stupidly,
zfree() never frees memory, but it works enough for this.
The purpose of using zlib is to implement gunzip() - this function
takes compressed data from in_buf, then dumps the decompressed data
to oub_buf. The work_buf is used for memory allocation during the
decompress. Upon exit, it updates in_buf and out_buf. If successful,
in_buf points to the end of input data, out_buf to the end of the
decompressed data.
To use this feature, you need to do:
- include lib/zlib/zlib.mk from your platform.mk
- add $(ZLIB_SOURCES) to your BL*_SOURCES

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.
