AArch32: Support in SP_MIN to receive arguments from BL2
...
This patch adds support in SP_MIN to receive generic and
platform specific arguments from BL2.
The new signature is as following:
void sp_min_early_platform_setup(void *from_bl2,
void *plat_params_from_bl2);
ARM platforms have been modified to use this support.
Note: Platforms may break if using old signature.
Default value for RESET_TO_SP_MIN is changed to 0.

AArch32: Common changes needed for BL1/BL2
...
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.

ARM platform changes for new version of image loading
...
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.

CSS: Implement support for NODE_HW_STATE

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.

Add WFI in platform's unexpected error handlers
...
This patch adds a WFI instruction in the default implementations of
plat_error_handler() and plat_panic_handler(). This potentially reduces
power consumption by allowing the hardware to enter a low-power state.
The same change has been made to the FVP and Juno platform ports.

AArch32: Add essential ARM platform and FVP support

This patch adds AArch32 support for FVP and implements common platform APIs
like `plat_get_my_stack`, `plat_set_my_stack`, `plat_my_core_cos` for AArch32.
Only Multi Processor(MP) implementations of these functions are considered in
this patch. The ARM Standard platform layer helpers are implemented for
AArch32 and the common makefiles are modified to cater for both AArch64 and
AArch32 builds. Compatibility with the deprecated platform API is not
supported for AArch32.

ARM platforms: Define common image sizes

ARM platforms: Define common image sizes
...
Compile option `ARM_BOARD_OPTIMISE_MMAP` has been renamed to
`ARM_BOARD_OPTIMISE_MEM` because it now applies not only to defines
related to the translation tables but to the image size as well.
The defines `PLAT_ARM_MAX_BL1_RW_SIZE`, `PLAT_ARM_MAX_BL2_SIZE` and
`PLAT_ARM_MAX_BL31_SIZE` have been moved to the file board_arm_def.h.
This way, ARM platforms no longer have to set their own values if
`ARM_BOARD_OPTIMISE_MEM=0` and they can specify optimized values
otherwise. The common sizes have been set to the highest values used
for any of the current build configurations.
This is needed because in some build configurations some images are
running out of space. This way there is a common set of values known
to work for all of them and it can be optimized for each particular
platform if needed.
The space reserved for BL2 when `TRUSTED_BOARD_BOOT=0` has been
increased. This is needed because when memory optimisations are
disabled the values for Juno of `PLAT_ARM_MMAP_ENTRIES` and
`MAX_XLAT_TABLES` are higher. If in this situation the code is
compiled in debug mode and with "-O0", the code won't fit.

Rework type usage in Trusted Firmware
...
This patch reworks type usage in generic code, drivers and ARM platform files
to make it more portable. The major changes done with respect to
type usage are as listed below:
* Use uintptr_t for storing address instead of uint64_t or unsigned long.
* Review usage of unsigned long as it can no longer be assumed to be 64 bit.
* Use u_register_t for register values whose width varies depending on
whether AArch64 or AArch32.
* Use generic C types where-ever possible.
In addition to the above changes, this patch also modifies format specifiers
in print invocations so that they are AArch64/AArch32 agnostic. Only files
related to upcoming feature development have been reworked.

ARM CSS platforms: Map flash as execute-never by default
...
On ARM CSS platforms, the whole flash used to be mapped as executable.
This is not required, given that the flash is used to store the BL1
and FIP images and:
- The FIP is not executed in place, its images are copied to RAM
and executed from there.
- BL1 is executed in place from flash but only its code needs to be
mapped as executable and platform code takes care of re-mapping
BL1's read-only section as executable.
Therefore, this patch now maps the flash as non-executable by default
on these platforms. This increases security by restricting the
executable region to what is strictly needed.
This patch also adds some comments to clarify the memory mapping
attributes on these platforms.

Introduce arm_setup_page_tables() function
...
This patch introduces the arm_setup_page_tables() function to
set up page tables on ARM platforms. It replaces the
arm_configure_mmu_elx() functions and does the same thing except
that it doesn't enable the MMU at the end. The idea is to reduce
the amount of per-EL code that is generated by the C preprocessor
by splitting the memory regions definitions and page tables creation
(which is generic) from the MMU enablement (which is the only per-EL
configuration).
As a consequence, the call to the enable_mmu_elx() function has been
moved up into the plat_arch_setup() hook. Any other ARM standard
platforms that use the functions `arm_configure_mmu_elx()` must be
updated.

Enable PSCI_STAT_COUNT/RESIDENCY for ARM standard platforms
...
This patch enables optional PSCI functions `PSCI_STAT_COUNT` and
`PSCI_STAT_RESIDENCY` for ARM standard platforms. The optional platform
API 'translate_power_state_by_mpidr()' is implemented for the Juno
platform. 'validate_power_state()' on Juno downgrades PSCI CPU_SUSPEND
requests for the system power level to the cluster power level.
Hence, it is not suitable for validating the 'power_state' parameter
passed in a PSCI_STAT_COUNT/RESIDENCY call.

It is up to the platform to implement the new plat_crash_print_regs macro to
report all relevant platform registers helpful for troubleshooting.
plat_crash_print_regs merges or calls previously defined plat_print_gic_regs

NOTE: THIS COMMIT REQUIRES ALL PLATFORMS THAT ENABLE THE `CRASH_REPORTING`
BUILD FLAG TO MIGRATE TO USE THE NEW `plat_crash_print_regs()` MACRO. BY
DEFAULT, `CRASH_REPORTING` IS ENABLED IN DEBUG BUILDS FOR ALL PLATFORMS.
