This would fix readv/writev issues mentioned in https://github.com/apache/nuttx/pull/12674. (only for this specific driver though. with this approach, we basically have to fix every single drivers and filesystems.) Lightly tested on the serial console, using micropython REPL on toywasm with esp32s3-devkit:toywasm, which used to be suffered by the readv issue.
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.
