Some entries have the opendir function set to NULL, for example
g_mount_operations.
A null pointer dereference can be triggered by an
opendir("/proc/fs/blocks") for example.

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.

There is no need for a gettid() syscall, as the thread ID is stable through
the life of the process. It is safe to put a copy of TID to TLS. This way
a user processes can access TID quickly via its own stack, instead of
having to use an expensive syscall.

We should not access semaphore internals directly outside sched/semaphore.
Just read it via the NXSEM_COUNT macro provided.

The defconfigs that select the ESP32-S3's WROOM-2-N32R8V module
contains an octal SPI flash chip and a octal SPIRAM module.
This commit updates the defconfig to avoid errors while booting the
device.

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
the existing Make.defs.

This commit adds support for the BMP180 sensor on the
STM32F401RC-RS485 board and updates the board documentation
accordingly. It also enables the BMP180 UORB driver in the
STM32 common logic.

This commit moves some internal libraries' .bss sections to the
external PSRAM chip, freeing internal memory for other usages. Note
that it is necessary to update `esp32s3-devkit:python` defconfig
otherwise it would fail to build.

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%
