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.
Signed-off-by: Chengdong Wang <wangchengdong@lixiang.com>
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.

This arch uses code relocation to SRAM through a XIP unit, so forcing segment
permissions manually in the linker script could create unforeseen issues.
A quick fix is setting the "--no-warn-rwx-segments" linker option just for
for the incriminated stage2 bootloader binary.

Enabling a higher channel of the internal ADC had the effect of
initializing the lower ones as well. Now that happens only if
actively requested.
Also, the functions for handling the internal ADC did not follow
the typical naming used by comparable modules for the same arch
and were renamed for coherence. Informational logging calls were
also made slightly more useful and discernible in case of having
multiple ADCs.

This patch fixes an incorrect call to stm32_cap_initialize() in
stm32_bringup.c: the call was made without the channel parameter.
Instead of adding the channel in the call, the channel is selected by
stm32_cap_gpio() (first available channel).
This patch also fixes incorrect driver registration in
drivers/timers/capture.c: the driver was registered with the wrong
name (/dev/cap -> /dev/capture). Also added more error checking in
cap_register_multiple().

This commit introduces a timer capture driver for the STM32H7 series
ported from the STM32 F series.
The main changes include:
- A new generic timer capture driver for STM32H7.
- A lower-half driver to integrate with the NuttX capture subsystem.
- Kconfig options to enable and configure capture for various timers.
- Pin definitions for TIM1-4 capture inputs on the nucleo-h743zi.
- An update to `cap_register_multiple` to handle multiple device registration.
- An update to `stm32_bringup` to register the capture drivers.
The current implementation is based on a driver originally for PWM input,
and as such, it calculates duty cycle and frequency. It is also limited
to a single capture channel per timer.
The original implementation's `stm32_cap_init` in
`arch/arm/src/stm32h7/stm32_capture.c` has been modified to accept a
channel number instead of using a hardcoded 0 through
`STM32_CAP_CHANNEL_COUNTER`.
This serves as a foundation for future development of more comprehensive
input capture capabilities on STM32H7 platforms.
Tested by polling and reading `/dev/cap0-4` with
`ioctl(fds[i], CAPIOC_FREQUENCE, freq)` while sending a square wave signal to
appropriate pins and checking frequency.
Also tested by bypassing upper half driver and setting up capture on
TIM4 channels 1-4 as explained in #16762.

This fixes the same issue for other targets, which was already fixed for
xtensa in commit 50d94863.
After the signals have been delivered, the local irqs need to be
disabled until the context switch. But just calling
leave_critical_section(regs[xx]) will enable them if they were
enabled in the context.

Clear dma interrupt flags as before.
Change HTEF to HTF, fixes typo.
Remove ALL_FLAGS define. Clear CXFCR with all 1s like other instances do.
Handle half-transfer interrupt only if in circular mode.
Add ADC_HAVE_DMA guard around adc_rstart_dma. It is needed because priv->circular is guarded by ADC_HAVE_DMA.
Many iMXRT MCUs have internally two USB OTG controllers, however
NuttX currently only supports one USB controllers. This patch will
prepare the "house" to support both ports at same time.
