URL: https://github.com/apache/nuttx/pull/16120

   
   ## Summary
   In the arm_el_init function, the FPU might be used, for example, the 
assembly optimization of memcpy uses FPU and NEON instructions and registers.
   Therefore, it's important to initialize the
   FPU as early as possible to prevent system hangs that could occur if the FPU 
is used without being initialized.
   
   
   ## Impact
   arch/arm/armv8-r  arch init
   
   ## Testing
   
   cortex-r52
