The length of some config elements are not equal to 1,2,4,8, so we can't
assert in virtio_mmio_config_read/write() direclty when length != 1,2,4,8
For example, in virtio_net_config from virtio spec v1.2
struct virtio_net_config {
u8 mac[6];
le16 status;
le16 max_virtqueue_pairs;
le16 mtu;
le32 speed;
u8 duplex;
u8 rss_max_key_size;
le16 rss_max_indirection_table_length;
le32 supported_hash_types;
};
The mac length is 6 and not equal to 1,2,4,8

The lower-half implementation of the RMT character driver based on
Espressif HAL enables using the RMT peripheral of ESP32, ESP32-S2
and ESP32-S3 as a common xtensa-based Espressif driver.
The RMT packages on Espressif SoCs are 4-byte long and are known as
"items". Please check the Techinal Reference Manual of the chip to
obtain more details.
Although the LED might be RGB-only, the LED data is packed in a
32-bit long variable and, then, this is the default size of a LED
pixel to define the 'WS2812_RW_PIXEL_SIZE' macro. Please note that
the lower-half driver will deal with the case of the addressable
LED being 3 or 4-pixel sized.
The RMT (Remote Control) character driver allows to use the RMT
peripheral (usually, a one-wire peripheral dedicated to driving
IR remote control) as a character driver.
Please note that this perpiheral depends on the lower-half specific
driver implementation.

The `xxx_ipv6multicast` function in each driver is not adapted to
multiple IPv6 addresses yet, and they're redundant, so try to take them
into common code.
Change:
1. Add MAC `g_ipv6_ethallnodes` and `g_ipv6_ethallrouters` in
`icmpv6_devinit` and call them in `netdev_register`
2. Add multicast MAC for Neighbor Solicitation when adding any IPv6
address, and remove them when IPv6 address is removed
3. Select `NET_MCASTGROUP` when `NET_ICMPv6` because now we need
`d_addmac` when we have ICMPv6
Note:
We want modules outside net stack to call functions like
`netdev_ipv6_add` and never touch the related MAC address, so these MAC
functions are added as internal functions to `net/netdev/netdev.h`

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.

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

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.

The ioctl command passes different parameters and commands, and interacts with the TEE through rpmsg.

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.
