The stack alignment operation in tricore and arm porting
only aligns the size of the stack, forget to align the start addr
of the stack, this patch fixes it.

Initial I2C implementation such that I2C sending and receiving now
works well enough to use the BMP280 driver for a BMP280 device connected
to any of I2C0-I2C6 on the default pins. I2CTOOL also works for these
interfaces.
Functionality for "no stop" and "no start" options is not present.
Implementing that is not clear from the peripheral datasheet and will be
a challenge.

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;
| }

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`.

On a system with multiple CPU cores, when the system is powered on,
multiple cores may start running simultaneously. In this case, software
is required to handle the startup logic for multi-core synchronization.
One approach is to use global variables.
however, the global variable region may not have been initialized yet.
In such scenarios, we can use a busywait flag to
implement the synchronization strategy.

"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.
