Add image_id to bl1_plat_handle_post/pre_image_load()
This patch adds an argument to bl1_plat_post/pre_image_load() APIs
to make it more future proof. The default implementation of
these are moved to `plat_bl1_common.c` file.
These APIs are now invoked appropriately in the FWU code path prior
to or post image loading by BL1 and are not restricted
to LOAD_IMAGE_V2.
The patch also reorganizes some common platform files. The previous
`plat_bl2_el3_common.c` and `platform_helpers_default.c` files are
merged into a new `plat_bl_common.c` file.
NOTE: The addition of an argument to the above mentioned platform APIs
is not expected to have a great impact because these APIs were only
recently added and are unlikely to be used.

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.

uniphier: allocate xlat region of on-chip SRAM only when needed
Currently, the xlat region of the on-chip SRAM is always allocated
for all BL images.
The access to the on-chip SRAM is necessary for loading images from
a USB memory device (i.e. when updating firmware), so unneeded for
the usual boot procedure.
To avoid this waste, allocate the xlat region dynamically only for
BL2, and only when it is necessary.

uniphier: get back original BL31/32 location used before BL2-AT-EL3
Commit
247fc0435191 ("uniphier: switch to BL2-AT-EL3 and remove BL1
support") accidentally changed the location of BL31 and BL32. The
new memory map overlaps with the audio DSP images, also gives impact
to OP-TEE. They are both out of control of ARM Trusted Firmware, so
not easy to change. This commit restores the image layout that was
originally used prior to the BL2-AT-EL3 migration.

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: add GZIP compression filter
One typical usage of the pre-tool image filter is data compression,

I guess this is generic enough to be put in the common script instead

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: merge build macros between FIP_ and FWU_FIP_

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

single macro call since the current MAKE_BL does not support fwu_fip.

fip, whereas if the argument is "FWU_", targeted to fwu_fip.
