This fixes issue on Ubuntu 22.04 with cmake v3.22.1:
```
/usr/bin/arm-none-eabi-gcc -D-DLFS_ASSERT=DEBUGASSERT -D-DLFS_CONFIG=/home/yf/Projects/Nuttx/nuttx/fs/littlefs/lfs_vfs.h -D-DLFS_DEBUG=finfo -D-DLFS_ERROR=ferr -D-DLFS_TRACE=finfo -D-DLFS_WARN=fwarn -DLFS_ATTR_MAX=1022 -DLFS_FILE_MAX=2147483647 -DLFS_NAME_MAX=32 -D__KERNEL__ -D__NuttX__
```

This selects ARM_THUMB for ARMV7R per ARM document:
https://developer.arm.com/documentation/dui0471
Thanks to hujun260 for spotting this, now ostest works.
Why it helps is still to be clarified, the `arm_signal_handler.S`
might require this THUMB option.
To keep ARM_THUMB as option, this only selects it for
PROTECTED as per anchao's suggestion.

Added documentation for espnow and a default defconfig to illustrate
the use of espnow for udp communication.
Signed-off-by: Laczen JMS <laczenjms@gmail.com>
Espnow is a connectionless WiFi communication protocol that can be used
to exchange information between esp nodes.
A espnow pktradio driver is proposed that allows building a 6lowpan
network of nodes.
The driver has been evaluated using udpclient & server running on
different devices.

The message RAM does not behave correctly if lower 16 bits of
buffer address overflow (upper 16 bits are set once in matrix driver
for the entire CAN driver). For example message RAM starting at
0x2040fc20 would not work for buffers that go beyond 0x20410000 and
MCAN would sent data located at 0x20400000 to the network. The same
issue would occur even if TX buffers would start directly at 0x20410000.
The upper 16 bits would still have 0x2040 value because of RX buffers
located in 0x2040ffff range.
This commit ensures the RAM is always located at the beginning of
the data section and thus the overflow mentioned above should never occur.
The alternative would be to use larger alignment, but the message RAM
can have up to 4352 words and this would cause a significant padding.
The RAM is also initialized to zero to ensure valid parity/ECC checksums.
The address issue is not described anywhere in the manual, so it is
possible this is caused by some incorrect configuration, but the context
of the registers looks valid.
This commit also fixes the compilation errors when the driver is run
without data cache.

GDB release 16.2 recently to fix the incompatibility issue with LLDB.
For us, the only change is stub must report it support feature 'binary-upload' before GDB will use this feature.
For more information, find bug report and discussion in https://sourceware.org/bugzilla/show_bug.cgi?id=32593
Use GDB 16.2, now it works with binary upload.

Fixed column formatting.

Added image to nucleo-h563zi documentation.
The CPCSTOP has a negative effect on the periodic timer operation.
This causes the timer to stop when an overrun occurs.
Timer must be then restarted in the interrupt. However, as interrupts
are not infinitely fast, this prolongs the next timeout.

The `$(APPDIR)` folder is added to the `$(KERNDEPDIRS)` when
`CONFIG_BUILD_KERNEL=y`. The `depend` phase iterates over the
`$(KERNDEPDIRS)` folders and executes the `depend` recipe of these
folders (including the apps' recipes) with the `__KERNEL__` macro
defined, which prevents `system()`'s prototype from being declared.
