The code is mainly derived from the NuttX qemu-rv/rv-virt codebase.
Major changes:
- boards/Kconfig: add new BOARD_K230_CANMV
- arch/risc-v/Kconfig: add new CHIP_K230 chip and ARCH_RV_MMIO_BITS
- arch/risc-v/src/common/riscv_mtimer.c: use ARCH_RV_MMIO_BITS to
select MMIO access width
New additions:
- arch/risc-v/include/k230/: k230 SoC definitions
- arch/risc-v/src/k230/: k230 SoC sources
- boards/risc-v/k230/canmv230/: CanMV-K230 board sources and configs
- Documentation/platforms/risc-v/k230/: simple doc
Note that only FLAT build works for canmv230 now.
This PR has changes in RiscV common layer thus may affect other RiscV ports
It changes the mtime/mtimecmp access control from using config ARCH_RV64 to
newly intorduced config ARCH_RV_MMIO_BITS.
Original design uses ARCH_RV64 to select 64bit MMIO in riscv_mtimer.c, this
can't cope with the situation with K230 --- it has ARCH_RV64 but only can do
32bit MMIO. So a new ARCH_RV_MMIO_BITS config has been introduced. Its value
depicts the MMIO width in bits. The MMIO_BITS defaults to 32/64 for RV32/
RV64 respectively. This allows the macro to replace current use of ARCH_RV64
in riscv_mtimer.c.
The new MMIO_BITS config is a derived one, and for RiscV chips with
equal CPU and MMIO widths there is no need to explicitly set it as the
default rule will do that. Only chips with different CPU and MMIO widths
need set it in Kconfig.
So by design this change should be safe but RiscV ports should be checked.
"ostest" verification has been done for:
- canmv230/nsh
- rv-vivt/nsh
- rv-virt/nsh64
configuration generation and manual check of derived RV_MMIO_BITS has been
done for:
- star64/nsh
- arty_a7/nsh
- bl602evb/nsh

External JLink is required to program the board, so the console via RTT
is available anyway. It is much more convenient to use than soldering the
P4 connector and working with an external UART converter.
We support search directory structure as follows:

To solve the issue of carrying object files from previous builds,
Matias changed the archiving process to re-archive libapps.a on every compilation,
if libapps.a carries more object files, incremental compilation will waste too
many time in re-archiving, compared with the previous implement, this is a degradation
of the build system. Referring to mature engineering projects such as cmake, if there
is configuration or source file changed, the best solution should be to reconfigure
the environment.
Revert this PR to ensure the compilation speed during incremental compilation.

| Fix: ensure archive files do not carry object files from prior builds
|
| In some cases, when NuttX configuration changes and this makes the
| object list used to build one of the .a libraries change as well,
| since the command used to build it is "ar crs" and this simply appends
| the list of object files, the library could still include object
| files from prior builds. This commit modifies the ARCHIVE macro to
| erase the .a file if it already exists.
|
| Since in some cases this behavior was actually expected (object
| files from a subdirectory were appended to a library created one
| level above) I added a ARCHIVE_ADD which works as ARCHIVE did.
|
| This change should greatly improve behavior of building after
| configuration changes.

The board-level GPIO support is different from the already existing
button and LEDC support because it enable us to register the GPIO
pins as devices in `/dev/gpioX`. Some applications are able to use
this interface to read and write the GPIO pins.
Documentation was added regarding its usage. Please check
`Documentation/platforms/xtensa/esp32s3/boards/esp32s3-devkit/index.rst`
According to `Documentation/guides/gdbwithpython.rst` and GDB's
documentation, the `-ix` option "Execute commands from file `file`
before loading the inferior (but after loading gdbinit files)",
being the correct way of loading it to GDB.

- NewReno congestion control algorithm is used to solve the problem
of network congestion breakdown. NewReno congestion control includes
slow start, collision avoidance, fast retransmission, and fast
recovery. The implementation refers to RFC6582 and RFC5681.
- In addition, we optimize the congestion algorithm. In the conflict
avoidance stage, the maximum congestion window max_cwnd is used to
limit the excessive growth of cwnd and prevent network jitter
caused by congestion. Maximum congestion window max_cwnd is updated
with the current congestion window cwnd and the update weight is
0.875 when an RTO timeout occurs.

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`
Adds support for the ES8311 codec on the ESP32-S2-Kaluga-1 board. This commit also adds basic configurations for testing and updates the board documentation.
Added examples of using the RTP Tools (`rtpdump`, in particular)
to receive RTP packets and 1) print the data and/or 2) playback
audio content through I2S.
