Considering kernel code, it's reasonable to use `PANIC()` instead
of `assert(0)` to handle with situations that require abort. Unlike
`assert`, `PANIC()` doesn't dependent on `NDEBUG`.
ESP32-S3 has only one 2.4 GHz ISM band RF module, which is shared
by Bluetooth and Wi-Fi, so Bluetooth can’t receive or transmit data
while Wi-Fi is receiving or transmitting data and vice versa.
Under such circumstances, ESP32-S3 uses the time-division
multiplexing method to receive and transmit packets.
The low-level Wi-Fi driver registers two peripheral interrupts to
the same CPU interrupt. Although the registered ISR is the same for
both peripherals interrupt, it's needed to call `up_enable_irq` to
ensure that the interrupt matrix is being set accordingly.
Please note that the current implementation of the ESP32-S3's IRQ
driver - although allow us to set a callback for each IRQ, which
represents the peripherals interrupt - doesn't allow us to call
both callbacks when these IRQs refers to a same CPU interrupt.
`g_cpu0_intmap` (or `g_cpu1_intmap`) associates each CPU interrupt
to a single IRQ/peripheral and, then, when a CPU interrupt is
triggered, only the last registered IRQ's callback will be called.
This isn't a problem here because 1) the registered callback is the
same for both IRQ's (in fact, it considers the CPU interrupt) and
2) we know in advance which peripheral interrupts will be attached
to which CPU interrupt and, then, we can set them directly.
This prevents us from getting stuck while polling the different
network structures in `devif_poll_connections`. This is useful for
Wi-Fi/Bluetooth coexistence, specifically.
- Fix macro values from `arch/xtensa/include/esp32s3/irq.h`
- Remove references to unexisting edge-triggered CPU interrupts
- Add `esp32s3_getirq` to get IRQ based on core and the `cpuint`
RTC subsystem controls not only the RTC itself but functions that
use RTC-enabled features like Bluetooth and Wi-Fi. Initialization
must be performed during the system start-up.
Adding the CONFIG_ARCH_PERF_EVENTS configuration to enable
hardware performance counting，solve the problem that some platform
hardware counting support is not perfect, you can choose to use
software interface.
This is configured using CONFIG_ARCH_PERF_EVENTS, so weak_functions
are removed to prevent confusion
To use hardware performance counting, must:
1. Configure CONFIG_ARCH_PERF_EVENTS, default selection
2. Call up_perf_init for initialization

- Added Wi-Fi related symbols to the kernel-space linker;
- Allocate more RAM to the kernel (to be useb by the Wi-Fi driver).
- Create a specific defconfig.
Instead of setting kernel/user space instruction and data ROM as
hard-coded values on linker, set them according to the max size
of the kernel image set by CONFIG_ESP32S3_KERNEL_IMAGE_SIZE. This
is done by making KIROM, UIROM, KDROM and UDROM dependent on the
kernel size value. Also, override CONFIG_NUTTX_USERSPACE config
according to CONFIG_ESP32S3_KERNEL_IMAGE_SIZE by using a custom
PREBUILD definition.
When supporting high-priority interrupts, updating the
g_running_tasks within a high-priority interrupt may be
cause problems. The g_running_tasks should only be updated
when it is determined that a task context switch has occurred.

Clone the esp-hal-3rdparty repository and, then, checkout to a
specific version (usually indicated by the commit SHA) instead of
using a branch as the HEAD.
If -fstack-protector-all is enabled, gcc linker will need GCC
SSP(Stack Smashing Protector) support, Since the implement of SSP
is related to the OS, most of embedded toolchain does not provide
ssp support, so an error will be reported when linking:
enable CONFIG_LTO_FULL && CONFIG_STACK_CANARIES
arm-none-eabi/bin/ld: cannot find -lssp_nonshared: No such file or directory
arm-none-eabi/bin/ld: cannot find -lssp: No such file or directory
https://github.com/gcc-mirror/gcc/blob/master/gcc/gcc.cc#L983-L985
Since nuttx has already implemented SSP related hook functions,
so in this PR, we filter out this option in the link phase to ensure that
the implementation of lssp/lssp_nonshared will not be referenced

In the current implementation of other architectures, it is not really implemented to preserve the context, so it is emulated from other architectures to clear the context.
If this behavior is not implemented, it will cause the xtensa architecture processor to loop assert in the active assert case
