For example a race in managing tcb->sigprocmask may cause signal not being delivered at all.
The mechanism is as follows:
1. cpu 1: nxsig_deliver adds the signal to the sigprocmask for the duration of signal delivery
2. cpu 2: new signal (same signo) is dispatched in nxsig_tcbdispatch
3. cpu 2: nxsig_tcbdispatch detects that signal is masked
4. cpu 2: nxsig_tcbdispatch leaves critical section before calling nxsig_add_pendigsignal
5. cpu 1: nxsig_deliver finishes. The "nxsig_unmask_pendingsignal" is called in the end but does nothing
6. cpu 2: nxsig_tcbdispatch continues and adds the pending signal
In the end, the logic in the end of nxsig_deliver, which tries to handle signals added
to the pending queue during the signal action delivery (step 5) failed, and the pending signal
was not delivered.
Fix this by just keeping the critical section for during the whole duration of nxsig_tcbdispatch,
and move things which can't be executed from within critical section outside.

The MCP47X6 series consists of the following single channel DAC chips:
- MCP4706 (8 bit)
- MCP4716 (10 bit)
- MCP4726 (12 bit)
The driver supports the following configurations:
- gain
- power down
- voltage reference
Persistent configuration storage in the internal EEPROM is not
implemented.
ax99100 export each serial port as a separate PCI device function
so we have to handle this properly.

as well as the `experimental` tag for indicating experimental boards and

The current solution is to directly use the target partition's number (num)
as next_seq to ensure the correct increment logic of seq. Ensure the formula
(seq-1) % OTA_DATA_NUM + OTA_IMG_BOOT_OTA_0 correctly maps to ota_0 or ota_1

To fix a fpu illegal instruction exception due to fcsr have invalid
rounding-mode, restore fcsr/f0~f31 with a random value from stack because fpu
context is not save into stack when mstatus.fs is clean(not dirty).
The number of save/restore fpu context operations is not equal.
In fact, CONFIG_ARCH_LAZYFPU is a performance optimization mechanism aimed at
minimizing the saving and restoring of FPU registers. In some cases, it
may only need to be saved once but must be restored multiple times.
Therefore, this optimization mechanism dictates that saving cannot be
done on the stack; it must be stored at a fixed location(e.g. task
control block buffer), as the stack requires push/pop operations to be
matched.
In case of that CONFIG_ARCH_LAZYFPU is off, save/restore FPU registers
always into stack to avoid the above issues.

The code used subi instruction to decrement the Y pointer but this
instruction only affects a byte, not a word. Fixed it by using
pre-decrement in the LD instruction instead.
The __flash qualifier only allows access to program memory below 64kB
mark (uses 16 bit pointer.) Since many chips currently supported
have more than that, this qualifier can prove insufficient.
When flagged __memx the compiler will use 24 bit pointer to access
the variable.
This commit adds support for the LCD based on ST7735 controller on
the STM32F401RC-RS485 board and updates the board documentation accordingly.

For some SMP calls it is necessary to lock the current CPU for the process
receiving the SMP call. This is done by setting the CPU affinity to the
current CPU and preventing the CPU selection algorithm from switching
CPUs.
dtcb->flags |= TCB_FLAG_CPU_LOCKED;
CPU_SET(dtcb->cpu, &dtcb->affinity);
However, this logic is currently broken, as CPU_SET is defined as:
#define CPU_SET(c,s) do { *(s) |= (1u << (c)); } while (0)
In order to assign tcb->cpu (the current CPU) to the affinity mask, the
mask must be cleared first by calling CPU_ZERO.
This adds filters field to icjx_config_s structure that is passed
as an argument in icjx_initialize function. This field allows to
configure I/O filters (control world 1 and 3) with three possible
filters or disable them at all.
The filter configuration is currently only configurable during the
initialization, not at run time (the same as current source)

for tcp_listener(). fixed potential conflict between implicit
binding and port conflict detection.
Implicit binding automatically allocates an interface address during
connection,but port conflict detection occurs before binding/connecting.
This can cause issues when creating multiple TCP connections in succession.
If the first connection uses a random port via implicit binding, subsequent
connections might reuse the same port under current filtering rules,
leading to connect() failures.
