If the current poll setup only has POLLIN, adding POLLOUT does not cause the
protocol stack to refocus on flags such as TCP_ACK or UDP_POLL, the user is
not notified when flags for POLLOUT relationships appear and vice versa,
so we have to call poll_setup again.

Move the mapping functionality from up_shmat/shmdt into two generic
mapping functions. This makes it possible to do other mappings besides
user shared memory area mappings.
RFC 1191
When a router is unable to forward a datagram because it exceeds the
MTU of the next-hop network and its Don't Fragment bit is set, the
router is required to return an ICMP Destination Unreachable message
to the source of the datagram, with the Code indicating
"fragmentation needed and DF set". To support the Path MTU Discovery
technique specified in this memo, the router MUST include the MTU of
that next-hop network in the low-order 16 bits of the ICMP header
field that is labelled "unused" in the ICMP specification [7]. The
high-order 16 bits remain unused, and MUST be set to zero. Thus, the
message has the following format:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Type = 3 | Code = 4 | Checksum |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| unused = 0 | Next-Hop MTU |

Description
A Packet Too Big MUST be sent by a router in response to a packet
that it cannot forward because the packet is larger than the MTU of
the outgoing link. The information in this message is used as part
of the Path MTU Discovery process [RFC-1191].

An off-by-one error caused invalid memory to be accessed when the
last port was used. The first entry, at index 0, was never used.
The USB standard uses 1-based numbering for hub ports. This number
was used to index an array. This change converts the port number to
a zero-based port index when the array is accessed. The zero-based
value in the port field of the usbhost_hubport_s structure is also
converted before printing.
For testing, this bug was exposed on a 4 port hub when port 4 was
used after changing USBHUB_MAX_PORTS to 4 in hub.h. The bug should
also be triggered without changing hub.h if a 7 port hub is
available.
During the serial reconfiguration from bootloader to the
NuttX a trash character "?" (Unicode replacement U+FFFD)
was printed in the screen.
This fix was discovered by Sylvio Alves from Espressif!
Instead of using Espressif's emulated NVS to save Wi-Fi data, use
`wapi`s wireless configure initialization mechanism for saving
Wi-Fi data. It 1) avoids creating a specific storage partition
just to save Wi-Fi data (ESP32-C3's storage partition is used
instead); 2) avoids initialization problems of the emulated NVS
when SMP is enabled (the Wi-Fi driver tries to initialize it before
the actual partition is initialized); and 3) enables reconnecting
using `wapi reconnect` command and connect the device automatically
on bringup if `CONFIG_NETUTILS_NETINIT` is selected.

Considering that the future fb needs to achieve dynamic resolution, the address and size of fbmem will be redistributed on the bottom driver side, so remove fbmem, fblen, and bpp cached in fb_chardev_s, and change it to call getplaneinfo every time to re-acquire panel info from the bottom driver. Avoid cache coherency problems.

Devices connected to the same USB bus should have unique function addresses.
This was not true for root hubs with multiple ports. After this change,
enumeration is more reliable on the sama5d3-xplained board when both root hub
ports are used.
This change amounts to using one usbhost_devaddr_s object per root hub
instead of one per root hub port. For the majority of boards only one
root hub port is available so no change in behavior should be expected.
Currently only Port UART0 is supported for Allwinner A64. This PR adds support for all UART Ports: UART1 to UART4. (Except R-UART, which is a special low-power UART)
This is required for the upcoming LTE Modem Driver (Quectel EG25-G) for PINE64 PinePhone, which uses UART3. [(Details here)](https://lupyuen.github.io/articles/lte2)
The code was adapted from the NuttX UART Driver for Allwinner A1X: [`a1x_serial.c`](https://github.com/apache/nuttx/blob/master/arch/arm/src/a1x/a1x_serial.c)
`arch/arm64/src/a64/a64_serial.c`: Added ports UART1 to UART4, based on [`a1x_serial.c`](https://github.com/apache/nuttx/blob/master/arch/arm/src/a1x/a1x_serial.c)
`arch/arm64/src/a64/a64_serial.h`: Added IRQs for UART1 to UART4. Moved UART Base Addresses to `a64_memorymap.h`
`arch/arm64/src/a64/hardware/a64_memorymap.h`: Added UART Base Addresses for UART0 to UART4
`arch/arm64/src/a64/Kconfig`: Added UART1 to UART4 to Allwinner A64 Peripheral Selection menu
`boards/arm64/a64/pinephone/configs/lcd/defconfig`, `lvgl/defconfig`, `nsh/defconfig`, `sensor/defconfig`: Fixed `UART1_SERIAL_CONSOLE` to `UART0_SERIAL_CONSOLE`
Commit 4d6a8663fa made pipes and
named pipes block when opening for O_WRONLY or O_RDONLY. Local
sockets, however, require `local_open_client_tx` to be non-blocking
to enable the server side to prevent the server side from blocking.
If set otherwise, it would deadly block. This commit sets the FIFO
as non-blocking temporarily, open the TX side and, if originally
blocking - restores it to that state.
This commit aims to enable the use of ROM functions on ESP32-S2.
This is done by creating the required syscall stubs table and adding the missing symbols to the linker script.

At present, the serial drivers qemu_serial.c and serial_pl011.c on the fvp-v8r and qemu platforms in arm64 are duplicated
and need to be merged. The plan is to place them under the drivers\serial directory to create a common code module,
so that both fvp-v8r and qemu can use the same code.
In the future, if new platforms use pl011 serial ports, they can also be directly reused
