This patch adds generic changes in BL2 to support AArch32 state.
New AArch32 specific assembly/C files are introduced and
some files are moved to AArch32/64 specific folders.
BL2 for AArch64 is refactored but functionally identical.
BL2 executes in Secure SVC mode in AArch32 state.

This patch adds common changes to support AArch32 state in
BL1 and BL2. Following are the changes:
* Added functions for disabling MMU from Secure state.
* Added AArch32 specific SMC function.
* Added semihosting support.
* Added reporting of unhandled exceptions.
* Added uniprocessor stack support.
* Added `el3_entrypoint_common` macro that can be
shared by BL1 and BL32 (SP_MIN) BL stages. The
`el3_entrypoint_common` is similar to the AArch64
counterpart with the main difference in the assembly
instructions and the registers that are relevant to
AArch32 execution state.
* Enabled `LOAD_IMAGE_V2` flag in Makefile for
`ARCH=aarch32` and added check to make sure that
platform has not overridden to disable it.

This patch adds changes in ARM platform code to use new
version of image loading.
Following are the major changes:
-Refactor the signatures for bl31_early_platform_setup()
and arm_bl31_early_platform_setup() function to use
`void *` instead of `bl31_params_t *`.
-Introduce `plat_arm_bl2_handle_scp_bl2()` to handle
loading of SCP_BL2 image from BL2.
-Remove usage of reserve_mem() function from
`arm_bl1_early_platform_setup()`
-Extract BL32 & BL33 entrypoint info, from the link list
passed by BL2, in `arm_bl31_early_platform_setup()`
-Provides weak definitions for following platform functions:
plat_get_bl_image_load_info
plat_get_next_bl_params
plat_flush_next_bl_params
bl2_plat_handle_post_image_load
-Instantiates a descriptor array for ARM platforms
describing image and entrypoint information for
`SCP_BL2`, `BL31`, `BL32` and `BL33` images.
All the above changes are conditionally compiled using the
`LOAD_IMAGE_V2` flag.

This patch adds changes in BL1 & BL2 to use new version
of image loading to load the BL images.
Following are the changes in BL1:
-Use new version of load_auth_image() to load BL2
-Modified `bl1_init_bl2_mem_layout()` to remove using
`reserve_mem()` and to calculate `bl2_mem_layout`.
`bl2_mem_layout` calculation now assumes that BL1 RW
data is at the top of the bl1_mem_layout, which is more
restrictive than the previous BL1 behaviour.
Following are the changes in BL2:
-The `bl2_main.c` is refactored and all the functions
for loading BLxx images are now moved to `bl2_image_load.c`
`bl2_main.c` now calls a top level `bl2_load_images()` to
load all the images that are applicable in BL2.
-Added new file `bl2_image_load_v2.c` that uses new version
of image loading to load the BL images in BL2.
All the above changes are conditionally compiled using the
`LOAD_IMAGE_V2` flag.

This patch adds capability to load BL images based on image
descriptors instead of hard coded way of loading BL images.
This framework is designed such that it can be readily adapted
by any BL stage that needs to load images.
In order to provide the above capability the following new
platform functions are introduced:
bl_load_info_t *plat_get_bl_image_load_info(void);
This function returns pointer to the list of images that the
platform has populated to load.
bl_params_t *plat_get_next_bl_params(void);
This function returns a pointer to the shared memory that the
platform has kept aside to pass trusted firmware related
information that next BL image needs.
void plat_flush_next_bl_params(void);
This function flushes to main memory all the params that
are passed to next image.
int bl2_plat_handle_post_image_load(unsigned int image_id)
This function can be used by the platforms to update/use
image information for given `image_id`.
`desc_image_load.c` contains utility functions which can be used
by the platforms to generate, load and executable, image list
based on the registered image descriptors.
This patch also adds new version of `load_image/load_auth_image`
functions in-order to achieve the above capability.
Following are the changes for the new version as compared to old:
- Refactor the signature and only keep image_id and image_info_t
arguments. Removed image_base argument as it is already passed
through image_info_t. Given that the BL image base addresses and
limit/size are already provided by the platforms, the meminfo_t
and entry_point_info arguments are not needed to provide/reserve
the extent of free memory for the given BL image.
- Added check for the image size against the defined max size.
This is needed because the image size could come from an
unauthenticated source (e.g. the FIP header).
To make this check, new member is added to the image_info_t
struct for identifying the image maximum size.
New flag `LOAD_IMAGE_V2` is added in the Makefile.
Default value is 0.
NOTE: `TRUSTED_BOARD_BOOT` is currently not supported when
`LOAD_IMAGE_V2` is enabled.

This patch implements CSS platform hook to support NODE_HW_STATE PSCI
API. The platform hook queries SCP to obtain CSS power state. Power
states returned by SCP are then converted to expected PSCI return codes.
Juno's PSCI operation structure is modified to use the CSS
implementation.

This patch adds support for NODE_HW_STATE PSCI API by introducing a new
PSCI platform hook (get_node_hw_state). The implementation validates
supplied arguments, and then invokes this platform-defined hook and
returns its result to the caller. PSCI capabilities are updated
accordingly.
Also updates porting and firmware design guides.

Restore some defines in xlat_tables.h

|
Add some missing forward declarations in plat_arm.h
|
|
This patch adds a couple of missing forward declarations in plat_arm.h
so that all types it references are known within this header file,
without relying on previous header inclusions. This concerns the
meminfo and bl31_params structures, which are defined in bl_common.h.
Other external types referenced from plat_arm.h (e.g. mmap_region_t)
get declared through header files included by arm_plat.h so they
don't need forward declarations.

Commit e8719552a24 removed some definitions related to translation

Instead of always calling the top level usage function when an
error is detected, call the command-specific usage function.
For example running `fiptool create` will produce the same output
as `fiptool help create`. This is more convenient for the user
when they make a mistake.

When using more than a single service in PMF, it is necessary that the
per-service timestamps begin on a cache line boundary. Previously it
was possible that two services shared a cache line for their
timestamps. This made it difficult to reason about cache maintenance
operations within a single service and required a global understanding
of how all services operate.

During system suspend, identify slaves which are configured
as wake sources and call pm_set_wakeup_source API for each of them.
Identifying if device may wake the system is done by checking if any
interrupt of that device is enabled in GICD_ISENABLER when the APU is
about to enter SUSPEND_TO_RAM state. If such interrupt is found,
pm_set_wakeup_source is called with corresponding PM node ID as
argument.

The state argument of the pm_self_suspend API encodes the state to
which the APU intends to suspend. The state can be:
- PM_APU_STATE_CPU_IDLE - processor power down, all memories remain
on
- PM_APU_STATE_SUSPEND_TO_RAM - all processors powered down, L2$
powered down, all OCM banks in retention and DDR in
self-refresh.
The calls for setting requirements for L2$ and OCM banks are now
redundant and removed.

Arm provided error injection support. To enable this error injection,
we need to set L2DEIEN in L2ACTLR_EL1 register and L1DEIEN in

This is needed for our cortexa53 edac linux driver testing.
These registers need write access from non secure EL1 i.e linux

Currently the GICv3 driver mandates that platform populate
both G1S and G0 interrupts. However, it is possible that a
given platform is not interested in both the groups and
just needs to specify either one of them.
This patch modifies the `gicv3_rdistif_init()` & `gicv3_distif_init()`
functions to allow either G1S or G0 interrupts to be configured.
