Add support for pthread_{get|set}concurrency support.
NuttX uses 1:1 threading model (every pthread is a kernel-managed thread),
so this function has no real effect on the scheduling behavior.

Add support for sigsetjmp() and siglongjmp().
This implementation is build on top of setjmp() and longjmp().
sigsetjmp() in that case must be implemented as a macro otherwise
we lose setjmp context.
siglongjmp() is kept as inline function to satisfy the PSE52 VSX
tests requirement.
An alternative implementation requires writing these function in
assembly code for each architecture.

The current logic failed silently on some systems, maybe because of a
different default shell? This resulted in builds that completed
successfully but generated invalid UF2 files, which were refused by
the uC bootloader.
Now the check is properly enforced and picotool is either found in
the $PATH or built from the pico-sdk source.

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

fix nooptimiziation_function definition problem for tricore gnu compiler
arch/tricore:
move tricore_csa2addr and tricore_addr2csa definition from include/arch.h to include/irq.h to fix build error
- Added esp32s3_board_spislavedev.c with board-level SPI slave logic
- Added esp32s3_board_spislavedev.h public header in common/include
- Updated Make.defs to include the new source when CONFIG_SPI_SLAVE_DRIVER=y
- Adding spislv board config to esp32s3-devkit
- Adding documentation of esp32s3 devkit spi slv
- Fixing path include in esp32s3_board_spislavedev.c
- Fixing relative path in the header of esp32s3_board_spislavedev.h
- Removing neasted check in Make.defs, consistency reasons
This provides initial support for SPI slave device initialization
on ESP32-S3 boards, making the feature available under conditional
build configuration.

When the task has TCB_FLAG_CPU_LOCKED it is locked to the CPU regardless

Since g_assignedtasks only holds the running task for each CPU, it can
be just a vector. Idle tasks are already preserved in statically allocated
structures "g_idletcb", and can be used from there.

This fixes several places, where the sched erroneously checks if the scheduling
is locked on current cpu/task, when it should check if the scheduling is locked
on the target cpu/task.
The original code randomly caused a task to be added to the pending list, and never
taken out from there, leading to system halt.
For SMP, there is no need for the pending list. Each CPU has got it's own
running list (assigned tasks list), and pending tasks can just be kept in
the unassigned (readytorun) list.
In addition, the smp scheduling is changed in a way that every CPU just picks
up the tasks from the ready-to-run list themselves. Which task to pick is
not tried to be dictated by another CPU.
This also allows using up_send_smp_sched for asynchronously
- re-prioritizing a running task
- triggering round robin scheduling switch
Iow, no separate smp call mechanism is needed for those and the code can be simplified.

Change every occurence of up_switch_context to use this_task() as the first parameter.
"nxsched_add_readytorun" returns "true" if context switch is required. "nxsched_add_readytorun"
typically could only switch the assigned/running task to the one which is passed in as parameter.
But this is not strictly guaranteed in SMP; if other CPUs tweak with affinities or priorities,
it may be possible that the running task after the call is changed, but is some other
task from the readytorun list (and it should be, if there is higher priority one available or the
affinity of the added task prevents it to be scheduled in, but the previous head of the readytorun
list should run.
this_task() is always the correct one to switch to, since it always points to the tcb which was
just switched in by the nxsched_add_readytorun.
This is also a precursor to re-writing the SMP queue logic to remove pending lists for SMP.

When exiting schedlock, that task should first take the critical section and
only after that decrease the lockcount to 0. Otherwise an interrupt might
cause a re-schedule before the task enters the critical section, which makes
the following code meaningless.

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.

If both SPI Flash support (`CONFIG_ESP32S3_SPIFLASH`) and PSRAM
(`CONFIG_ESP32S3_SPIRAM`) are enabled, the PSRAM can only be
assigned to the user's heap (`CONFIG_ESP32S3_SPIRAM_USER_HEAP`).
Additionaly, `CONFIG_ESP32S3_SPI_FLASH_SUPPORT_PSRAM_STACK` must be
set because the system will end up allocating tasks' stacks from
the external PSRAM. This has an impact when dealing with SPI flash
operations because the cache must be disabled and the running task
should not rely on any data from the PSRAM. To accomplish that, It
offloads the SPI flash operation to a work queue (which, by
definition, allocates its heap from the kernel heap).
The same (assigning the PSRAM to the user's heap) is valid when the
Wi-Fi is enabled because the lower-half driver requires data being
allocated from the internal memory (which can only be achieved by
allocating from the kernel heap when both the kernel and user heaps
exists).

The interrupt handler accesses the device as well as the driver's private
data. Thus, must take the big kernel lock in SMP mode to protect them.
Signed-off-by: Jukka Laitinen <jukka.laitinen@tii.ae>
In SMP mode one CPU can be executing the MMC interrupt while another CPU
disables (e.g. via watchdog timeout). As it is disabled the other CPU
assumes it's safe to start configuring the device after this.
This causes a leak in the driver's private data as well as a mutual
exclusion leak on the device itself.
Fix this by aborting any triggered interrupt by checking whether it's
even enabled.
