Yann Gautier 48ede66151 feat(stm32mp1): update memory mapping for STM32MP13
SYSRAM is only 128KB and starts at 0x2FFE0000.
SRAMs are added.
BL2 code and DTB sizes are also reduced to fit in 128KB.

- STM32MP153: Dual Cortex-A7
- STM32MP157: + GPU and DSI, but not needed for TF-A

file.

There are 4 packages available, for which  the IOs number change. Have one
file for each package. The 2 packages AB and AD are added.

STM32157A-DK1 and STM32MP157C-DK2 share most of their features, a common
dkx file is then created.

Some reordering is done in other files, and realign with kernel DT files.

The DDR files are generated with our internal tool, no changes in the
registers values.

Etienne Carriere fdaaaeb431 stm32mp1: SCMI clock and reset service in SP_MIN
This change implements platform services for stm32mp1 to expose clock
and reset controllers over SCMI clock and reset domain protocols
in sp_min firmware.

Requests execution use a fastcall SMC context using a SiP function ID.
The setup allows the create SCMI channels by assigning a specific
SiP SMC function ID for each channel/agent identifier defined. In this
change, stm32mp1 exposes a single channel and hence expects single
agent at a time.

The input payload in copied in secure memory before the message
in passed through the SCMI server drivers. BL32/sp_min is invoked
for a single SCMI message processing and always returns with a
synchronous response message passed back to the caller agent.

This change fixes and updates STM32_COMMON_SIP_NUM_CALLS that was
previously wrongly set 4 whereas only 1 SiP SMC function ID was to
be counted. STM32_COMMON_SIP_NUM_CALLS is now set to 3 since the
2 added SiP SMC function IDs for SCMI services.

Etienne Carriere 0754143ac9 stm32mp1: use last page of SYSRAM as SCMI shared memory
SCMI shared memory is used to exchange message payloads between
secure SCMI services and non-secure SCMI agents. It is mapped
uncached (device) mainly to conform to existing support in
the Linux kernel. Note that executive messages are mostly short
(few 32bit words) hence not using cache will not penalize much
performances.

secure and non-secure areas of the SYSRAM address space, that before
CPU accesses the shared memory when mapped non-secure.

Madhukar Pappireddy ca661a0092 Enable -Wredundant-decls warning check
This flag warns if anything is declared more than once in the same
scope, even in cases where multiple declaration is valid and changes
nothing.

Consequently, this patch also fixes the issues reported by this
flag. Consider the following two lines of code from two different source
files(bl_common.h and bl31_plat_setup.c):

IMPORT_SYM(uintptr_t, __RO_START__, BL_CODE_BASE);
IMPORT_SYM(unsigned long, __RO_START__, BL2_RO_BASE);

The IMPORT_SYM macro which actually imports a linker symbol as a C expression.
The macro defines the __RO_START__ as an extern variable twice, one for each
instance. __RO_START__ symbol is defined by the linker script to mark the start
of the Read-Only area of the memory map.

Essentially, the platform code redefines the linker symbol with a different
(relevant) name rather than using the standard symbol. A simple solution to
fix this issue in the platform code for redundant declarations warning is
to remove the second IMPORT_SYM and replace it with following assignment

static const unsigned long BL2_RO_BASE = BL_CODE_BASE;

Yann Gautier 10e7a9e904 stm32mp1: print information about board
On STMicroelectronics boards, the board information is stored in OTP.
This OTP is described in device tree, in BSEC board_id node.

Yann Gautier 73680c230f stm32mp1: add watchdog support
Introduce driver for STM32 IWDG peripheral (Independent Watchdog).
It is configured according to device tree content and should be enabled
from there.
The watchdog is not started by default. It can be started after an HW
reset if the dedicated OTP is fused.

The watchdog also needs to be frozen if a debugger is attached.
This is done by configuring the correct bits in DBGMCU.
This configuration is allowed by checking BSEC properties.

An increase of BL2 size is also required when adding this new code.

Julius Werner d5dfdeb65f Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__
NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

Yann Gautier f33b2433f5 stm32mp1: add general SYSCFG management
The system configuration controller is mainly used to manage
the compensation cell and other IOs and system related settings.

The SYSCFG driver is in charge of configuring masters on the interconnect,
IO compensation, low voltage boards, or pull-ups for boot pins.
All other configurations should be handled in Linux drivers requiring it.

Device tree files are also updated to manage vdd-supply regulator.

Yann Gautier 1989a19c2d stm32mp1: add OP-TEE support
Support booting OP-TEE as BL32 boot stage and secure runtime
service.

OP-TEE executes in internal RAM and uses a secure DDR area to store
the pager pagestore. Memory mapping and TZC are configured accordingly
prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
a header file describes the effective boot images. This change
post processes header file content to get OP-TEE load addresses
and set OP-TEE boot arguments.
