clk: stm32mp1: use defines for mask values in stm32mp1_clk_sel array ...

Rework the macro that eases the table definition: the src and msk fields
are now using MASK and SHIFT defines of each source register.
Some macros had then to be modified: _USART1_SEL, _ASS_SEL and _MSS_SEL to
_UART1_SEL, _AXIS_SEL, and _MCUS_SEL to match register fields.

Note: the mask for RCC_ASSCKSELR_AXISSRC is changed from 0x3 to 0x7
to reflect the size of the register field, even if there are only
3 possible clock sources.

The mask value is also corrected for QSPI and FMC clock selection.

clk: stm32mp1: move oscillator functions to generic file ...

Those functions are generic for parsing nodes from device tree
hence could be located in generic source file.

The oscillators description structure is also moved to STM32MP1 clock
driver, as it is no more used in stm32mp1_clkfunc and cannot be in a
generic file.

Fix type of cot_desc_ptr ...

The chain of trust description and the pointer pointing to its first
element were incompatible, thus requiring an explicit type cast for
the assignment.

- cot_desc was an array of
  const pointers to const image descriptors.

- cot_desc_ptr was a const pointer to
  (non-constant) pointers to const image descriptors.

Thus, trying to assign cot_desc to cot_desc_ptr (with no cast) would
generate the following compiler warning:

drivers/auth/tbbr/tbbr_cot.c:826:14: warning: initialization discards
  ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
 REGISTER_COT(cot_desc);

Neoverse N1: Introduce workaround for Neoverse N1 erratum 1315703 ...

Neoverse N1 erratum 1315703 is a Cat A (rare) erratum [1], present in
older revisions of the Neoverse N1 processor core.
The workaround is to set a bit in the implementation defined CPUACTLR2_EL1
system register, which will disable the load-bypass-store feature.

Add support for Branch Target Identification ...

This patch adds the functionality needed for platforms to provide
Branch Target Identification (BTI) extension, introduced to AArch64
in Armv8.5-A by adding BTI instruction used to mark valid targets
for indirect branches. The patch sets new GP bit [50] to the stage 1
Translation Table Block and Page entries to denote guarded EL3 code
pages which will cause processor to trap instructions in protected
pages trying to perform an indirect branch to any instruction other
than BTI.
BTI feature is selected by BRANCH_PROTECTION option which supersedes
the previous ENABLE_PAUTH used for Armv8.3-A Pointer Authentication
and is disabled by default. Enabling BTI requires compiler support
and was tested with GCC versions 9.0.0, 9.0.1 and 10.0.0.
The assembly macros and helpers are modified to accommodate the BTI
instruction.
This is an experimental feature.
Note. The previous ENABLE_PAUTH build option to enable PAuth in EL3
is now made as an internal flag and BRANCH_PROTECTION flag should be
used instead to enable Pointer Authentication.
Note. USE_LIBROM=1 option is currently not supported.

Add option for defining platform DRAM2 base ...

The default DRAM2 base address for Arm platforms
is 0x880000000. However, on some platforms the
firmware may want to move the start address to
a different value.

To support this introduce PLAT_ARM_DRAM2_BASE that
defaults to 0x880000000; but can be overridden by
a platform (e.g. in platform_def.h).

SMMUv3: Abort DMA transactions ...

For security DMA should be blocked at the SMMU by default
unless explicitly enabled for a device. SMMU is disabled
after reset with all streams bypassing the SMMU, and
abortion of all incoming transactions implements a default
deny policy on reset.
This patch also moves "bl1_platform_setup()" function from
arm_bl1_setup.c to FVP platforms' fvp_bl1_setup.c and
fvp_ve_bl1_setup.c files.

plat/arm: introduce wrapper functions to setup secure watchdog ...

The BL1 stage setup code for ARM platforms sets up the SP805 watchdog
controller as the secure watchdog. But not all ARM platforms use SP805
as the secure watchdog controller.

So introduce two new ARM platform code specific wrapper functions to
start and stop the secure watchdog. These functions then replace the
calls to SP805 driver in common BL1 setup code. All the ARM platforms
implement these wrapper functions by either calling into SP805 driver
or the SBSA watchdog driver.
