Rust/D support for RISC-V is broken after https://github.com/apache/nuttx/pull/11549,
since the target triple is quite different bewteen Rust/D toolchain and GCC,
only few RISC-V targets are supported by Rust toolchain now, so it's better to
construct target triple in Rust.defs/D.defs for RISC-V.
Add configuration and driver support for the SSD1681 1.54 inch e-paper display,
including the necessary waveforms and settings for proper operation. This extends
the existing SSD1680 e-paper driver to accommodate the new display module.
The changes involve updates to the Kconfig file for additional configuration options,
modifications to the driver implementation in ssd1680.c to include SSD1681 specific
logic, and updates to the header file ssd1680.h to reflect the added support.

This revises PROTECTED build for qemu-rv mainly to avoid hard-coded
addresses in linker scripts. It also added rv32 support, cleaned up
config `pnsh64` and added config `pnsh`.

This triggers `mm_free_delaylist()` before dumping status in PROTECTED
build, otherwise the `free` command still shows delaylist as `used`.

This adds explicit `void mm_free_delaylist(heap)` interface so that
to force freeing the heap's delaylist.

This adds NuttSBI support for rv-virt device so that to enable CI
checks for NuttSBI later. It allows using `-bios nuttx` option to
run NuttX with QEMU v6.2 w/o OpenSBI.

This adjusts sbi_start behavior so that if SBI late initialization hook
is defined, PMP setting is assumed to be fully done in the hook, because
the default PMP operation may fail for various reasons such as lacking
free entries or the default setting doesn't work on devices like QEMU
v6.2.

Two things need to be done when vfork'ing:
- Must attach to parent's address environment (the addrenv is shared)
- Must allocate a kernel stack (where would the register context go otherwise)
Note that this code assumes the address environment is shared, since we
don't support fork() which would _clone_ the address environment instead.
HPET can be used as system clock for x86_64
to set HPET as system clock you have to enable:
CONFIG_ONESHOT=y
CONFIG_ALARM_ARCH=y
CONFIG_INTEL64_ONESHOT=y
CONFIG_ARCH_INTEL64_HPET_ALARM=y

When setting the sample rate (`es8311_setsamplerate`) and the bits
per sample (`es8311_setbitspersample`), check their return value in
`es8311_configure`. Also, this commit ensures that these functions
are called after `es8311_reset` to avoid these values to be set to
the default values.
The ESP32-S3-Korvo-2 is a multimedia development board based on the
ESP32-S3 chip. It is equipped with a two-microphone array which is
suitable for voice recognition and near/far-field voice wake-up
applications. The board integrates multiple peripherals such as
LCD, camera, and microSD card. It also supports JPEG video stream
processing. With all of its outstanding features, the board is an
ideal choice for the development of low-cost and low-power
network-connected audio and video products.
Other ESP32-S3 modules (with embedded flash and PSRAM) were added.
Also, the `help` section of the Kconfig was updated to better
describe the modules' flash and PSRAM sizes.
Steppoint can be implemented by icount(instruction count)
from RISC-V debug extension, but it may not implemented in all RISC-V cores.
Unfortunately, the currently supported RISC-V cores do not implement it.

According to the POSIX standard, `fstat` and `stat` should return 0
(`OK`) on success. This commit changed the underlying `spiffs`
implementation to follow the POSIX standard.
Provide `up_copy_section` function that enables copying data using
the data bus. If the memory destination address is accessible
through the instruction bus, the data is copied using the
correspondent address accessible through the data bus.
The ELF loader needs to load the app into the memory before
executing it from the same location. As expected, this memory space
should be able to execute code. For architectures containing data
and instruction buses, the instruction bus may not be able to be
accessed in a non-aligned way, which is usually required when
copying data to that location. Eventually, this same memory space
can be accessed through the data bus, using different address
ranges. This commit enables accessing the memory through the data
bus to copy the app's data before executing it when
`CONFIG_ARCH_HAVE_TEXT_HEAP_WORD_ALIGNED_READ` is enabled.
