Manish V Badarkhe 570c71b20a fix(stm32mp1): include assert.h to fix build failure
stm32mp1 platform build failed with the error [1] in the coverity, to
fix it included assert.h file.

Yann Gautier 2deff904a9 fix(st): fix NULL pointer dereference issues
The get_bl_mem_params_node() function could return NULL. Add asserts to
check the return value is not NULL.
This corrects coverity issues:
	pager_mem_params = get_bl_mem_params_node(BL32_EXTRA1_IMAGE_ID);
>>>     CID 378360:    (NULL_RETURNS)
>>>     Dereferencing "pager_mem_params", which is known to be "NULL".

	paged_mem_params = get_bl_mem_params_node(BL32_EXTRA2_IMAGE_ID);
>>>     CID 378360:    (NULL_RETURNS)
>>>     Dereferencing "paged_mem_params", which is known to be "NULL".

	tos_fw_mem_params = get_bl_mem_params_node(TOS_FW_CONFIG_ID);
>>>     CID 378360:    (NULL_RETURNS)
>>>     Dereferencing "tos_fw_mem_params", which is known to be "NULL".


Do the same for other occurrences of get_bl_mem_params_node() return not
checked, in the functions plat_get_bl_image_load_info() and
bl2_plat_handle_pre_image_load().

Yann Gautier 1d204ee4ab feat(plat/st): use FIP to load images
BL2 still uses the STM32 header binary format to be loaded from ROM code.
BL32 and BL33 and their respective device tree files are now put together
in a FIP file.
One DTB is created for each BL. To reduce their sizes, 2 new dtsi file are
in charge of removing useless nodes for a given BL. This is done because
BL2 and BL32 share the same device tree files base.

The previous way of booting is still available, the compilation flag
STM32MP_USE_STM32IMAGE has to be set to 1 in the make command. Some files
are duplicated and their names modified with _stm32_ to avoid too much
switches in the code.

Yann Gautier 84686ba347 stm32mp1: dynamically map DDR later and non-cacheable during its test
A speculative accesses to DDR could be done whereas it was not reachable
and could lead to bus stall.
To correct this the dynamic mapping in MMU is used.
A first mapping is done for DDR tests with MT_NON_CACHEABLE attribute,
once DDR access is setup. It is then unmapped and a new mapping DDR is done
with cacheable attribute (through MT_MEMORY) to speed-up BL33 (or OP-TEE)
load.

The disabling of cache during DDR tests is also removed, as now useless.
A call to new functions stm32mp_{,un}map_ddr_non_cacheable() is done
instead.

PLAT_XLAT_TABLES_DYNAMIC is activated globally as used in BL2 and BL32.

BL33 max size is also updated to take into account the secure and shared
memory areas. Those are used in OP-TEE case.

Antonio Nino Diaz 09d40e0e08 Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Yann Gautier 4353bb20cc Introduce STMicroelectronics STM32MP1 platform
STM32MP1 is a microprocessor designed by STMicroelectronics,
based on a dual Arm Cortex-A7.
It is an Armv7-A platform, using dedicated code from TF-A.

STM32MP1 uses BL2 compiled with BL2_AT_EL3.
