Cleanup the code for TBBR CoT descriptors ...

CoT used for BL1 and BL2 are moved to tbbr_cot_bl1.c
and tbbr_cot_bl2.c respectively.
Common CoT used across BL1 and BL2 are moved to
tbbr_cot_common.c.

drivers: stm32mp1 clocks: fix debug trace on clock enable/disable ...

Adds missing terminal new line character '\n' to debug traces,
fix format as index is an unsigned value and use present tense rather
than past tense in the printed message.

drivers: stm32mp1 clocks: prevent crash on always on clocks ...

Oscillators and PLLs are not gated on stm32mp_clk_enable/disable()
calls. This change prevents functions to panic when called for such
always-on clocks. Gating these clocks is out of the scope of
this change.

drivers: stm32mp1 clocks: add RTC as a gateable clock ...

Adds RTC clock to the list of the supported clocks. This allows
stm32mp_clk_*() API functions to enable, disable and set and get
rate for the clock RTC clock.

drivers: stm32mp1 clocks: support shifted clock selector bit masks ...

The current implementation optimizes memory consumed by gateable
clock table by storing bit mask and bit shift with 1 byte each.
The issue is that register selector bit masks above the 7th LSBit
cannot be stored.

This change uses the shift info to shift the mask before it is used,
allowing clock selector register bit fields to be spread on the 32 bits
of the register as long as the mask fits in 8 contiguous bit at most.

This change is needed to add the RTC clock to the gateable clocks table.

drivers: stm32mp1 clocks: allow tree lookup for several system clocks ...

Oscillators, PLLs and some system clocks can be related straight to
a parent clock. Prior this change were only oscillators and few
clocks supported by this look up. This changes adds PLLs and other
system clocks. This enables for flexible use of clock tree exploration
when computing a clock frequency value.

plat/stm32: Use generic fdt_get_reg_props_by_name() ...

The STM32 platform port parse DT nodes to find base address to
peripherals. It does this by using its own implementation, even though
this functionality is generic and actually widely useful outside of the
STM32 code.

Re-implement fdt_get_reg_props_by_name() on top of the newly introduced
fdt_get_reg_props_by_index() function, and move it to fdt_wrapper.c.
This is removes the assumption that #address-cells and #size-cells are
always one.

plat/stm32: Implement fdt_read_uint32_default() as a wrapper ...

The STM32 platform code uses its own set of FDT helper functions,
although some of them are fairly generic.

Remove the implementation of fdt_read_uint32_default() and implement it
on top of the newly introduced fdt_read_uint32() function, then convert
all users over.

This also fixes two callers, which were slightly abusing the "default"
semantic.

plat/stm32: Use generic fdt_read_uint32_array() implementation ...

The device tree parsing code for the STM32 platform is using its own FDT
helper functions, some of them being rather generic.
In particular the existing fdt_read_uint32_array() implementation is now
almost identical to the new generic code in fdt_wrappers.c, so we can
remove the ST specific version and adjust the existing callers.

Compared to the original ST implementation the new version takes a
pointer to the DTB as the first argument, and also swaps the order of
the number of cells and the pointer.

TF-A GICv3 driver: Change API for GICR_IPRIORITYR accessors ...

To support compatibility with previous GICv3 driver version
this patch:
- restores original API for gicr_read_ipriority() and
gicr_wrtite_ipriority() functions;
- adds accessor functions for GICR_XXX0,1 registers, e.g.
GICR_IGROUPR0, GICR_ICFGR0, GICR_ICFGR1, etc.

gic multichip: add support for clayton ...

GIC-Clayton supports multichip operation mode which allows it to connect
upto 16 other GIC-Clayton instances. GIC-Clayton's multichip programming
and operation remains same as GIC-600 with a minor change in the
SPI_BLOCKS and SPI_BLOCK_MIN shifts to accommodate additional SPI
ranges. So identify if the GIC v4 extension is enabled by the platform
makefile and appropriately select the SPI_BLOCKS and SPI_BLOCK_MIN
shifts.
