When opening a FIFO with O_RDONLY or O_WRONLY set:
* If O_NONBLOCK is set, an open() for reading-only shall return
without delay. An open() for writing-only shall return an error
if no process currently has the file open for reading.
* If O_NONBLOCK is clear, an open() for reading-only shall block
the calling thread until a thread opens the file for writing.
An open() for writing-only shall block the calling thread until
a thread opens the file for reading.

1 Similar to Linux and zephyr, all implementations are in arm64_arch_timer.c
2 Arm64 tickless is turned off by default. If it needs to be turned on, you need to configure the switch CONFIG_SCHED_TICKLESS ON
3 The implementation strategy for tick/tickless is to use the timer inside the CPU and implement the timer driver based on the ARCH_TIMER framework.
4 We implemented tick_* Callback functions to adapt to the driven interface to avoid time format conversion overhead
5 In arm64_tick_cancel func，The remaining time that is not used, so this value can be ignored without reading the corresponding register to obtain the remaining cycles
6 Currently, tick/tickless can takes effect in SMP and non SMP mode, ostest can pass.

Implement local mode control (ECHO only) for telnet, this allow application to disable ECHO of telnet, it's useful to input password during shell login and other case.
Signed-off-by: Huang Qi <huangqi3@xiaomi.com>
If TELNET_CHARACTER_MODE is set, the ECHO must be handled by the telnet server.
So this option is useless. We need a new approach to control the ECHO behavior.

Instead of using a volatile storage for the address environment in the
binfmt / loadinfo structures, always allocate the address environment
from kheap.
This serves two purposes:
- If the task creation fails, any kernel thread that depends on the
address environment created during task creation will not lose their
mappings (because they hold a reference to it)
- The current address environment variable (g_addrenv) will NEVER contain
a stale / incorrect value
- Releasing the address environment is simplified as any pointer given
to addrenv_drop() can be assumed to be heap memory
- Makes the kludge function addrenv_clear_current irrelevant, as the
system will NEVER have invalid mappings any more
This way the mappings can be modified for any vm area, not only the
process that is running.
Why? This allows mapping pages to kernel dynamically, this functionality
will be presented later.
The rpmsg addr get from socket accept has rp_family=0, which is not
intended, to avoid wrong logic in other place, set the rp_family
in ns_bind function.

Pinmaps should not have contained GPIO_SPEED_xxx settings and
all pins should have had suffixes to allow any pins attributes to
be set. This is board dependent.
This change adds CONFIG_STM32L5_USE_LEGACY_PINMAP to allow for
lazy migration to using pinmaps with suffixes.
The work required to do this can be aided by running tools/stm32_pinmap_tool.py.
The tools will take a board.h file and a legacy pinmap and outut the required
changes that one needs to make to a board.h file.
Eventually, CONFIG_STM32L5_USE_LEGACY_PINMAP will be deprecated and the legacy
pinmaps removed from NuttX.
Any new boards added should set CONFIG_STM32L5_USE_LEGACY_PINMAP=n and

The text describes an issue related to the running task in code.
The running task is only used when calling the _assert function
to indicate the task that was running before an exception occurred.
However, the current code only updates the running task during
irq_dispatch, which is suitable for ARM-M architecture but not
for ARM-A or ARM-R architecture, because their context switches
are not done through irq handler. Therefore, if the following
process is followed, the value of the running task will be incorrect:
1. task1 is running, this_task()=task1
2. do_irq is executed, setting running task()=task1
3. task1 switches to task2
4. task2 is running and generates a data abort
5. In the data abort, the _assert function is called,
and the running task obtained is still task1, but
the actual task that generated the exception is task2.
