lld will produce warnings for the symtab, strtab, and shstrtab sections
if --orphan-handling=warn is specified and there are no matching rules
in the linker script for these sections. Handle these sections when
building with lld to prevent the warnings.
This is exactly the same as commit
c420733c33, but for the AE350 linker
script.

As well described in a previous PR [1], the GNU ld and LLVM lld linkers
treat the location counter (`.`) differently. lld always inteprets the
location counter as an absolute address whereas ld interprets it as an
offset from the start of the current object.
The NXP boot header linker script files use `.` assignment to specify an
offset within the rom_start region (ld-style). This causes lld to error
out since it interprets this as the location counter moving backwards.
To fix this, re-use the idea from the previous PR [1]:
replace `. = FOO` with `. += FOO - (. - __rom_start_address)`
This sets the location counter in a way that works with both ld and lld.

Intel Audio DSP ACE needs to use arch_spin_relax() to give
the bus more time to propagate the RCW transactions among
CPUs, and to avoid sending too many requests to the bus
after failing to lock spinlocks. However, the number of
NOPs results in a very big arch_spin_relax() that spans
multiple instruction cache lines, and requires evicting
them just for NOPs. With 5 CPUs, it can span 6 cache
lines (if using nop.n instead of nop). That's a waste of
space and cache. So instead, we do a tight loop instead.
Since the SoC supports zero-overhead loops, this should
have minimal performance impact.

For some weird unknown reasons, the simulator really do not
like the cpuhold_* variables to be tightly packed together.
This results in cpuhold_spawned not being updated, and we
will be stuck in the while loop for it to be set.
Workaround this by explicitly aligning these variables on
16 byte boundary. This seems to work for now.

In the default configuration, cv32a6 does not have an FPU and does not
implement RISC-V's F and D extensions.
Hence, the FPU flags should not be added.
In the future, a second SoC for cv32a6 systems with FPU can be added.

The original commit uses the incorrect value 42 for
CONFIG_MAX_IRQ_PER_AGGREGATOR for the cva6 family of SoCs,
which is the total number of IRQs in the system.
This commit corrects this to 30, the number of IRQs for the PLIC.

In hardware, cva6 currently only provides global disable/enable
functions for the Dcache and Icache. Disabling and re-enabling them also
has the effect of flushing and invalidating the cache.
Future cva6 SoCs will add support RISC-V's standardized cache management
operations.
This commit provides a default implementation for all methods currently
part of the cache API. These implementations can be overwritten at board
or SoC level, as they use weak linking.

Chip siwx91x has 672kB of SRAM shared between the Cortex-M4 (Zephyr) and
the NWP (Network Processor). 3 memory configurations are possible for
the Cortex-M4:
- 196kB
- 256kB
- 320kB
Less memory is allocated to Zephyr, more memory is allocated to NWP,
better are the WiFi and BLE performances.

Silabs siwx91x hardware use specific memory areas to store descriptors
for DMA requests. These areas are tightly coupled between the CPU and
the hardware. This helps in reducing the wait cycles.
Until now these addresses was also hard coded in the DT and in the
linker script. This patch leverage the zephyr,memory-region driver to
centralize the information in the DT.
Then, with this new implementation, the memory mapping is easier to
understand for the reader.

Microchip MEC was configuring the kernel timer tick rate at the
board level instead of the SoC level. We unify all this by moving
the Kconfig logic out of the board level into each mec chip.
We also derive SYS_CLOCK_HW_TICKS_PER_SEC from the device tree
node enabled for the kernel timer: Microchip's 32 KHz RTOT timer
or Cortex-M4 SYSTICK. The soc kconfig rules are loading all mec
subdirectories for every build causing warnings when building
new socs with this change. We made the changes for all the mec chips.

Adds support for the CVA6 family of RISC-V CPUs.
CVA6 is commonly found as a soft core CPU on FPGA designs.
Different configurations and instruction set extensions can be
configured, and different SoCs targeting various FPGA boards are
available.
This commit adds support for the 32-bit and 64-bit configurations
of CVA6, as well as three slightly different SoCs (a minimal 32-bit
configuration, a 64-bit configuration without FPU, a 64-bit
configuration with FPU).
