Make: fix dependency files generation
...
Currently, if no make goal is specified in the command line, 'all'
is assumed by default, but the dependency files are not generated.
This might lead to a successful but inconsistent build. This patch
provides a fix to the problem.

Rework Makefile
...
This patch is a complete rework of the main Makefile. Functionality
remains the same but the code has been reorganized in sections in
order to improve readability and facilitate adding future extensions.
A new file 'build_macros.mk' has been created and will contain common
definitions (variables, macros, etc) that may be used from the main
Makefile and other platform specific makefiles.
A new macro 'FIP_ADD_IMG' has been introduced and it will allow the
platform to specify binary images and the necessary checks for a
successful build. Platforms that require a BL30 image no longer need
to specify the NEED_BL30 option. The main Makefile is now completely
unaware of additional images not built as part of Trusted Firmware,
like BL30. It is the platform responsibility to specify images using
the macro 'FIP_ADD_IMG'. Juno uses this macro to include the BL30
image in the build.
BL33 image is specified in the main Makefile to preserve backward
compatibility with the NEED_BL33 option. Otherwise, platform ports
that rely on the definition of NEED_BL33 might break.
All Trusted Board Boot related definitions have been moved to a
separate file 'tbbr_tools.mk'. The main Makefile will include this
file unless the platform indicates otherwise by setting the variable
'INCLUDE_TBBR_MK := 0' in the corresponding platform.mk file. This
will keep backward compatibility but ideally each platform should
include the corresponding TBB .mk file in platform.mk.

Use standard errno definitions in load_auth_image()
...
This patch replaces custom definitions used as return values for
the load_auth_image() function with standard error codes defined
in errno.h. The custom definitions have been removed.
It also replaces the usage of IO framework error custom definitions,
which have been deprecated. Standard errno definitions are used
instead.

IO Framework: use standard errno codes as return values
...
This patch redefines the values of IO_FAIL, IO_NOT_SUPPORTED and
IO_RESOURCES_EXHAUSTED to match the corresponding definitions in
errno.h:
#define IO_FAIL (-ENOENT)
#define IO_NOT_SUPPORTED (-ENODEV)
#define IO_RESOURCES_EXHAUSTED (-ENOMEM)
NOTE: please note that the IO_FAIL, IO_NOT_SUPPORTED and
IO_RESOURCES_EXHAUSTED definitions are considered deprecated
and their usage should be avoided. Callers should rely on errno.h
definitions when checking the return values of IO functions.

cert_create: specify command line options in the CoT
...
This patch introduces a new API that allows to specify command
line options in the Chain of Trust description. These command line
options may be used to specify parameters related to the CoT (i.e.
keys or certificates), instead of keeping a hardcoded list of
options in main.c.

cert_create: improve command line argument check
...
The certificate generation tool currently checks if all command
line options required to create all certificates in the CoT have
been specified. This prevents using the tool to create individual
certificates when the whole CoT is not required.
This patch improves the checking function so only those options
required by the certificates specified in the command line are
verified.

Add optional bl1_plat_prepare_exit() API
...
This patch adds an optional API to the platform port:
void bl1_plat_prepare_exit(void);
This function is called prior to exiting BL1 in response to the
RUN_IMAGE_SMC request raised by BL2. It should be used to perform
platform specific clean up or bookkeeping operations before
transferring control to the next image.
A weak empty definition of this function has been provided to
preserve platform backwards compatibility.

Reorganise PSCI PM handler setup on ARM Standard platforms
...
This patch does the following reorganization to psci power management (PM)
handler setup for ARM standard platform ports :
1. The mailbox programming required during `plat_setup_psci_ops()` is identical
for all ARM platforms. Hence the implementation of this API is now moved
to the common `arm_pm.c` file. Each ARM platform now must define the
PLAT_ARM_TRUSTED_MAILBOX_BASE macro, which in current platforms is the same
as ARM_SHARED_RAM_BASE.
2. The PSCI PM handler callback structure, `plat_psci_ops`, must now be
exported via `plat_arm_psci_pm_ops`. This allows the common implementation
of `plat_setup_psci_ops()` to return a platform specific `plat_psci_ops`.
In the case of CSS platforms, a default weak implementation of the same is
provided in `css_pm.c` which can be overridden by each CSS platform.
3. For CSS platforms, the PSCI PM handlers defined in `css_pm.c` are now
made library functions and a new header file `css_pm.h` is added to export
these generic PM handlers. This allows the platform to reuse the
adequate CSS PM handlers and redefine others which need to be customized
when overriding the default `plat_arm_psci_pm_ops` in `css_pm.c`.

Break down BL1 AArch64 synchronous exception handler
...
The AArch64 synchronous exception vector code in BL1 is almost
reaching its architectural limit of 32 instructions. This means
there is very little space for this code to grow.
This patch reduces the size of the exception vector code by
moving most of its code in a function to which we branch from
SynchronousExceptionA64.

Make CASSERT() macro callable from anywhere
...
The CASSERT() macro introduces a typedef for the sole purpose of
triggering a compilation error if the condition to check is false.
This typedef is not used afterwards. As a consequence, when the
CASSERT() macro is called from withing a function block, the compiler
complains and outputs the following error message:
error: typedef 'msg' locally defined but not used [-Werror=unused-local-typedefs]
This patch adds the "unused" attribute for the aforementioned
typedef. This silences the compiler warning and thus makes the
CASSERT() macro callable from within function blocks as well.

Fix #include path in ARM platform BL1 setup code
...
This patch fixes the relative path to the 'bl1_private.h' header file
included from 'arm_bl1_setup.c'. Note that, although the path was
incorrect, it wasn't causing a compilation error because the header
file still got included through an alternative include search path.

TLKD: pass results with TLK_RESUME_FID function ID
...
TLK sends the "preempted" event to the NS world along with an
identifier for certain use cases. The NS world driver is then
expected to take appropriate action depending on the identifier
value. Upon completion, the NS world driver then sends the
results to TLK (via x1-x3) with the TLK_RESUME_FID function ID.
This patch uses the already present code to pass the results
from the NS world to TLK for the TLK_RESUME_FID function ID.

This patch fixes an issue in the PSCI framework where the affinity info

CPU_OFF request. Now, the state remains set to ON instead.

Send power management events to the Trusted OS (TLK)
...
This patch adds PM handlers to TLKD for the system suspend/resume and
system poweroff/reset cases. TLK expects all SMCs through a single
handler, which then fork out into multiple handlers depending on the
SMC. We tap into the same single entrypoint by restoring the S-EL1
context before passing the PM event via register 'x0'. On completion
of the PM event, TLK sends a completion SMC and TLKD then moves on
with the PM process.

Bug fix in the SP804 dual timer driver
...
The generic delay timer driver expects a pointer to a timer_ops_t
structure containing the specific timer driver information. It
doesn't make a copy of the structure, instead it just keeps the
pointer. Therefore, this pointer must remain valid over time.
The SP804 driver doesn't satisfy this requirement. The
sp804_timer_init() macro creates a temporary instanciation of the
timer_ops_t structure on the fly and passes it to the generic
delay timer. When this temporary instanciation gets deallocated,
the generic delay timer is left with a pointer to invalid data.
This patch fixes this bug by statically allocating the SP804
timer_ops_t structure.
