The functions `hw_write_masked` and `hw_xor_bits` (as defined in
pico-sdk) were defined in NuttX twice.
Additionally these definitions were in conflict (one lacked the
`volatile` modifier).
Now these functions and their dependencies are defined in a new header
file.
Its name is based on the filename of the original definition in
pico-sdk:
src/rp2_common/hardware_base/include/hardware/address_mapped.h
This change should fix the potential issue of GPIO operations failing
due to compiler optimizations caused by the absence of `volatile`.

Since the alignment of the signal context is affected by XCPTCONTEXT_SIZE in
different Kconfig, sometimes the stack pointer is not aligned to 8 bytes, this
is not what the software and compiler expect, for example, if va_list() obtains
wide data of type long long, the offset will be wrong, So in this commit, we set
stack-aligned the base offset so that the correct offset will be set during context
restoration.
1. test code:
| void signal_handler(int signo, siginfo_t *info, void *context) {
| long long ttt = 1024000;
| printf("%lld\n", ttt);
| }
|
| struct itimerspec its = { .it_value.tv_sec = 1,
| .it_value.tv_nsec = 0,
| .it_interval.tv_sec = 1,
| .it_interval.tv_nsec = 0
| };
|
| int main(int argc, FAR char *argv[])
| {
| struct sigevent evp;
| timer_t timer_id;
|
| memset(&evp, 0, sizeof(evp));
| evp.sigev_notify = SIGEV_SIGNAL | SIGEV_THREAD_ID;
| evp.sigev_signo = SIGALRM;
| evp.sigev_notify_thread_id = gettid();
|
| timer_create(CLOCK_REALTIME, &evp, &timer_id);
|
|
| struct sigaction sa;
| memset(&sa, 0, sizeof(sa));
| sa.sa_sigaction = signal_handler;
| sa.sa_flags = SA_SIGINFO;
| sigemptyset(&sa.sa_mask);
|
| sigaction(SIGALRM, &sa, NULL);
|
| timer_settime(timer_id, 0, &its, NULL);
|
| while (1)
| sleep(1);
|
| return 0;
| }

This patch addresses several issues and adds enhancements to the WWDG
(Window Watchdog) implementation for the STM32H7 platform. The changes
include:
- Extend the definitions of WWDG_CFR_PCLK1 macros to support dividers
up to 128, and update the stm32_settimeout() function to consider this
extended range.
- Fix the "elapsed" calculations in the stm32_getstatus() function to
ensure correct time remaining calculations.
- Clear the EWIF (Early Wakeup Interrupt Flag) bit in the stm32_start()
function, as this bit might be set by hardware before the watchdog is
actually started.
- Initialize the WWDG clock in the RCC_APB3ENR register and set the
RCC_GCR_WW1RSC bit as per the STM32 reference manual to ensure proper
behavior when enabling the WWDG1.

"tc397" is a chip name which is not appropriate to act as a board name.
the board supported here is actually "a2g-tc397-5v-tft".
The correct definition is : tricore is arch name, tc3xx is arch family
name, tc397 is chip name and the borad name is a2g-tc397-5v-tft
imx9_lpi2c_reset didn't quite work. It tried to toggle scl line as GPIO, but the line was not even muxed properly.
Instead, set the bus to relaxed mode, and drive address 0 to the bus. This toggles the clock, and also generates start and stop sequences on the bus.
"Relaxed mode" is a new feature on the LPI2C block used in imx93.

Introduce EXT1 wakeup functionality to the ESP32-S3 power management
subsystem. With this feature, the ESP32-S3 can wake up from PM_STANDBY
or PM_SLEEP when one or more RTC GPIOs trigger the EXT1 condition.
Changes include:
- Added EXT1 wakeup configuration and preparation logic in rtc code.
- Integrated EXT1 handling in pmstandby() and pmsleep().
- New board-level Kconfig options under ESP32-S3 DevKit menu:
- CONFIG_PM_EXT1_WAKEUP: enable EXT1 wakeup support
- CONFIG_PM_EXT1_WAKEUP_RTC_GPIO<n>: select RTC GPIOs as wake sources
- CONFIG_PM_EXT1_WAKEUP_TRIGGER_MODE: choose wakeup on HIGH or LOW level
- Fixing Kconfig style
- Fixing comments standard
- Adding PM documentation for esp32s3-devkit
Impact:
- No build impact unless CONFIG_PM_EXT1_WAKEUP is enabled.
- When enabled, ESP32-S3 can wake from low-power states via RTC GPIOs.
- No new public API introduced; controlled via board Kconfig.
Tested on ESP32-S3 DevKit:
- Configured GPIO4 and GPIO5 as EXT1 wake sources.
- Verified wakeup from light sleep and deep sleep on external signals.
- Wakeup reason correctly reported as EXT1.

Prior to this commit, it wasn't possible to load ELF modules from
the external PSRAM. There were two main issues about it: 1) copying
data using the instruction bus was being used instead of the data
bus (this, per si, isn't a problem, but requires special attention
regarding data alignment), and 2) the cache was not being properly
cleaned and flushed to properly access the loaded data using the
instruction bus.
