Shoji Tokunaga 3d446bd674 tools/rust: Move NuttX Rust target specs into nuttx
Move the NuttX-specific Rust target specification files from apps/tools
to nuttx/tools so files with the same purpose are kept in one place.

The existing aarch64 Mach-O target spec for macOS simulator builds
already lives under nuttx/tools. Keeping the remaining NuttX Rust target
specs there as well makes the layout consistent and lets both Make and
CMake builds refer to target specs from the NuttX tree.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
