The default mode for Rpmsgdev is to read/write data as long as possible for
caller, this mode does not apply to tun devices, tun devices can read and
write only one complete ip packet at a time.

The `SIZEOF_ICMPV6_ECHO_REQUEST_S` and `SIZEOF_ICMPV6_ECHO_REPLY_S`
macro are intended to be `8+n`, but actually becomes `10-1+n` and causes
the packet sent by `ping6` one byte more than expected.

virtio mmio version 1 and 2);
3. virtio-serial driver based on new virtio framework;
4. virtio-rng driver based on new virtio framework;
5. virtio-net driver based on new virtio framework
(IOB Offload implementation);
6. virtio-blk driver based on new virtio framework;
7. Remove the old virtio mmio framework, the old framework only
support mmio transport layer, and the new framwork support
more transport layer and this commit has implemented all the
old virtio drivers;
8. Refresh the the qemu-arm64 and qemu-riscv virtio related
configs, and update its README.txt;
New virtio-net driver has better performance

A sensor of this type measures the force on it, and additionally
compares the force with one or more specified thresholds. The sensor
can output the force value directly. Moreover, it's usually applied
as a press key. In that case, when it detects a force greater than
some given threshold, a corresponding event is reported.

so we need to use lib_free to deallocate memory otherwise the assertion

This provides the initial hooks for Flattened Device Tree support
with QEMU RV. It also provides a new procfs file that exposes the
fdt to userspace much like the /sys/firmware/fdt endpoint in Linux.
See https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-firmware-ofw
Nodes in the fdt are not yet usable by the OS.

Some IO expanders have more advance options for pins and communication.
This is used to pass driver dependend structure to expander driver.

This adds support for 16 bit io expander pcf8575. The driver is basically
the same as for pcf8574 however it is for 16 bits instead of 8 bits. Since
pcf8575 and pcf8574 can be both used on the same i2c bus the driver for
pcf8575 is implemented in a different file to reduce the code size
and complexity and to have less if statements in the driver.

Some UART Controllers (Synopsys DesignWare 8250) will trigger spurious interrupts when the Line Control Register (LCR) is set while the UART is busy. This patch provides the option (16550_WAIT_LCR) to wait for UART until it's not busy, before setting the LCR. (16550_WAIT_LCR is disabled by default)
This patch fixes the spurious UART interrupts for the upcoming port of NuttX to StarFive JH7110 SoC (with Synopsys DesignWare 8250 UART). [The patch is explained here](https://lupyuen.github.io/articles/plic#appendix-fix-the-spurious-uart-interrupts)
drivers/serial/uart_16550.c: If 16550_WAIT_LCR is enabled, wait until UART is not busy before setting LCR
include/nuttx/serial/uart_16550.h: Define the UART Status Register (USR) for checking if UART is busy
drivers/serial/Kconfig-16550: Added option 16550_WAIT_LCR to 16550 UART Config, disabled by default
No memory map count limit that will exhaust memory and cause
the system hang. Also that fix pass LTP posix case mmap/24-1.c
