If a process causes a fatal error when it's running a system call, the
whole system should crash as the crash originated from the kernel.
Do this by running the PANIC() branch, if task is in syscall.

This commit fixes the SPI flash frequency selection for ESP32-S2,
enabling the Kconfig macros to be selected when ESP32-S2 SoC is
enabled. Please note that this was recently changed to make it
compatible with already existing SPI flash Kconfig macros for ESP32
and ESP32-S3 and it introduced this regression for ESP32-S2.

SPI flash operation modes - Dual Output (dout), Dual I/O (dio),
Quad Output (qout), Quad I/O (qio) and Octal (opi) were not being
properly selected. This commit fixes this behavior and the device
is now able to boot and initialize the proper SPI flash mode.

boards/arm: Add CMakeLists for the nucleo-l476rg.
Adds CMakeLists files for the STM32L4 architectures
and one of the development boards. Files are adapted
from the similar STM32F7 boards, but built to reflect

This commit moves some internal libraries' .bss sections to the

Optimize crc32 standard(poly:0x04C11DB7) and crc32
castagnoli(poly:0x1EDC6F41) with arm crc32 extension instructions.
For example, crc32 standard caculates(lookup crc32 table) 1812 bytes data,
reduced the time from 118 us to 14 us through optimization.
Performance improved ~700%

In the arm_el_init function, the FPU might be used, for example, the
assembly optimization of memcpy in arm_tcm_load uses FPU and NEON
instructions and registers.
Therefore, it's important to initialize the
FPU as early as possible to prevent system hangs that could occur if the
FPU is used without being initialized.

This commit fixed `fb_putc` for early-print.
- Modified fb_putc to return an int instead of void.
- Handled error cases where the character is not found by replacing it with a '.'.
- Ensured cursor position is updated correctly after each character is processed.
- Fixed above 4G framebuffer memory mapping.

The default frequency for the SPI flash chip on ESP32-H2 is 64MHz.
Although it was being set to 48MHz, this isn't a valid value. The
device, however, must be flashed using 48MHz when 64MHz is set.
Remove call to enter_critical_section (big kernel lock) and replace it
with a smaller lock to protect the USB clock and its reference counter.

If the remote end just closes an endpoint and no longer handles it,
the system is prone to intensive cpu polling via mpfs_write_tx_fifo()
especially if the device side doesn't know a thing about what the
remote did.
Fix this by marking the EP as dead, which will skip all writes causing
unnecessary polling. The EP is back in business if the remote end
sends some data (rx) or the connection is re-established.

GPIO peripheral clocks have to be enabled even if interrupt support
on the peripheral is not enabled, otherwise GPIO input will not work.
This is probably caused by input filters that need clock signal.
This commit moves the clock enable call from interrupt specific function
to common initialization function that is called from _start entry
point function.

Summary:
stm32: support querying a previously set RTC alarm In the STM32F1xx series
Impact:
When using the stm32f1xx series MCU, the alarm function can be used, but when we enabled the CONFIG_RTC_ALARM configuration, an error was reported due to the inability to find the specific implementation of rdalarm.
Testing:
In our own projects, we have done alarm verification using the STM32F103RE..
The CONFIG item is beneficial for startup performance tuning, so
it would be better to have it in Nuttx as well.
