[GitHub] [nuttx] lucasssvaz opened a new pull request, #9242: arch/xtensa/esp32[s2]: Define syscall table to enable using ROM functions

lucasssvaz opened a new pull request, #9242:
URL: https://github.com/apache/nuttx/pull/9242

   ## Summary
   
   This MR aims to enable the use of ROM functions on ESP32 and ESP32-S2.
   This is done by creating the required syscall stubs tables and add the missing symbols to the linker scripts. 
   
   ## Impact
   
   Adds support for using ROM functions when needed. Shouldn't impact existing code.
   
   ## Testing
   
   Tested locally using `ostest`.

   The use of the name "system call" seems odd and somewhat inappropriate.  A system call normally refers to the application interface to the operating system and often involves call gates.  For example:  https://en.wikipedia.org/wiki/System_call
   
   I would have recommended using a name like ROM call rather than system call.   The name ROM call is used for other architectures for this kind of interface.
