Pinmaps should not have contained GPIO_SPEED_xxx settings.
This is board dependent.
This change adds CONFIG_STM32_USE_LEGACY_PINMAP to allow for
lazy migration to using pinmaps without speeds.
The work required to do this can be aided by running tools/stm32_pinmap_tool.py.
The tools will take a board.h file and a legacy pinmap and outut the required
changes that one needs to make to a board.h file.
Eventually, STM32_USE_LEGACY_PINMAP will be deprecated and the legacy
pinmaps removed from NuttX.
Any new boards added should set STM32_USE_LEGACY_PINMAP=n and
fully define the pins in board.h

The text describes an issue related to the running task in code.
The running task is only used when calling the _assert function
to indicate the task that was running before an exception occurred.
However, the current code only updates the running task during
irq_dispatch, which is suitable for ARM-M architecture but not
for ARM-A or ARM-R architecture, because their context switches
are not done through irq handler. Therefore, if the following
process is followed, the value of the running task will be incorrect:
1. task1 is running, this_task()=task1
2. do_irq is executed, setting running task()=task1
3. task1 switches to task2
4. task2 is running and generates a data abort
5. In the data abort, the _assert function is called,
and the running task obtained is still task1, but
the actual task that generated the exception is task2.

Over-drive can be forced to a given state by adding define to the
board.h configuration file:
#define STM32_VOS_OVERDRIVE 1 - force over-drive enabled,
#define STM32_VOS_OVERDRIVE 0 - force over-drive disabled,
#undef STM32_VOS_OVERDRIVE - autoselect over-drive by the default RCC logic
It seems that over-drive is not required for ULPI but it can be a workaround solution for boards with poor signal integration.
Higher core voltage means faster clock signal edges, which may be sufficient to synchronize the high-speed clock and data on poorly designed boards.
Over-drive can be forced to a given state by adding define to the
board.h configuration file:
#define STM32_VOS_OVERDRIVE 1 - force over-drive enabled,
#define STM32_VOS_OVERDRIVE 0 - force over-drive disabled,
#undef STM32_VOS_OVERDRIVE - autoselect over-drive by the default RCC logic
- Remove the temporary "saved" variable when temporarily changing MMU
mappings to access another process's memory. The fact that it has an
address environment is enough to make the choice
- Restore nxflat_addrenv_restore-macro. It was accidentally lost when
the address environment handling was re-factored.
On a GICv2 implementation, setting GICC_CTLR.EOImode to 1 separates
the priority drop and interrupt deactivation operations.

Summary:
- Support arm64 pmu api, Currently only the cycle counter function is supported.
- Using ARM64 PMU hardware capability to implement perf interface, modify all
perf interface related code.
- Support for pmu init under smp.

Otherwise, a request will never be transferred and there is no
information to the user that something is wrong.
For example, when using default values for TXFIFO in HS mode,
USBMSC will never work because the maximum request len is 512B
which is lower than the default TXFIFO size for IN EP.
Current Toolchain.defs set the compile flags directly, it's OK for
target specified gcc toolchain.
But some LLVM based toolchains (Rust/Zig etc) use single toolchain to handle all supported paltform.
In this patch, arch level Toolchain.defs export standard LLVM style arch flags, and let <Lang>.defs to map them into internal style,
This will simplify the intergration of non-c language.

arm-none-eabi-gcc 12.2.0 gives the following warnings:
error: 'primask' is used uninitialized
error: 'primask' may be used uninitialized
We use Werror and the file is indirectly included in different
places. I suggest telling the compiler to ignore these warnings
since primask is initialized on the first assembly line.
This is the only problem I encountered so far when upgrading the compiler.
SPI transfers are dynamically determined to use DMA or not.
The flag to judge is removed in a previous simple refactoring commit.
Revert the logic and fix an issue that SPI transfer fails.
