A driver SHOULD negotiate VIRTIO_NET_F_MAC if the device offers it.
If the driver negotiates the VIRTIO_NET_F_MAC feature, the driver MUST
set the physical address of the NIC to mac. Otherwise, it SHOULD use a
locally-administered MAC address.

Commit 8a63d29c removed `devif_iob_send` from `udp_sendto_buffered`
workflow, `devif_iob_send` drops too big packet. Now we still need a
place to check the packet length, otherwise a packet larger than MTU
may be sent to the net driver.
In case of similar problem happens somewhere else, this commit also
adds a check in `netdev_upperhalf`, and count these cases into
`NETDEV_TXERRORS`.

Busy waiting in w25qxxxjv_erase_sector() was without nxsig_usleep and
was causing the entire system to freeze for significant amount of time
as sector erase takes some time.
This commit adds nxsig_usleep into busy waiting to prevent system lock.
Sleep is set to sector erase time based on W25Q series datasheet.

1. read/write memory
2. Use watchpoint,breakpoint,single step.
use up_debugpoint api
3. Ctrl+c to stop, continue, or single step.
hold uart send and receive
4. register a panic event, when crash or assert/panic, we use uart to

Add registration function instrumentation API,
which can achieve instrumentation of entering and
exiting functions through the compiler's functionality.
We can use CONFIG_ARCH_INSTRUMENT_ALL to add instrumentation for all
source, or add '-finstrument-functions' to CFLAGS for Part of the
source.
Notice:
1. use CONFIG_ARCH_INSTRUMENT_ALL must mark _start or entry noinstrument_function,
becuase bss not set.
2. Make sure your callbacks are not instrumented recursively.
use instrument_register to register entry function and exit function.
They will be called by the instrumented function

Previously CONFIG_USBDEV_SOFINTERRUPT existed in many platform
drivers but did nothing. This commit adds a callback function
usbdev_sof_irq() that can be used to take action on this interrupt.
To avoid losing the first frame, the set_buf needs to excute first. At the same time, imgdata->start_capture should excuted before the imgsensor->start_capture.

The driver's main purpose is to support the porting of the open source
component optee_client (https://github.com/OP-TEE/optee_client) to nttux.
The basic function of the driver module is to convert the REE application layer data and send it to the TEE through rpmsg.
The main functions include
1 driver registration.
we need to register a device driver(/dev/tee0) through optee_register function.
2 open the driver
3 ioctl the driver
The ioctl command passes different parameters and commands, and interacts with the TEE through rpmsg.

There are ICs available on the market that integrate various power inverter
features. The driver for such a device must be tightly coupled to a FOC device
as using it as a separate device doesn't make sense.

Previous adjtime() implementation was limited to adjusting system
timer tick period. This commit reimplements the internals to use
a kernel watchdog timer. Platform-independent part of the code now
works also for adjusting hires RTC and tickless timer rate.
User code facing API is unchanged. Architecture code API has changed:
up_adj_timer_period() is replaced by up_adjtime().
Other improvements:
- Support query of remaining adjustment by passing NULL to first
argument of adjtime(). This matches Linux behavior.
- Improve resolution available for architecture driver, previously
limited to 1 microsecond per tick. Now 1 nanosecond per second.
In order to achieve better scalability, change the stride
from pixel mode to byte mode.For example, in the case of RGB888
mode with 466 pixels in width and a 4-byte aligned buffer,it is
only necessary to extend the buffer of one line from 1398 bytes
to 1400 bytes, instead of extending it to 1404 bytes.

These values are board-specific properties that must be known on the application side.
Until now, these values had to be hardcoded on the application side.
When we record data and dump data, they are all executed within the system,
and there is no need to consider the issue of big or small endianness.

In `drivers/rptun/rptun.c`, we have a `rptun_is_recursive` function,
which lets rptun thread run recursively. Then the `usrsock_rpmsg_ept_cb`
may be called inside `usrsock_rpmsg_ept_cb`, which can cause some
unexpected behavior, so we add a queue to keep the order of incoming
messages to reduce the complexity.
