+ * Description:
+ * Configure the syscall table used by the ROM code for calling C library
+ * functions.
+ * ESP32-C3 ROM code contains implementations of some of C library
+ * functions. Whenever a function in ROM needs to use a syscall, it calls
+ * a pointer to the corresponding syscall implementation defined in the
+ * syscall_stub_table struct.
+ *
+ * Input Parameters:
+ * None.
+ *
+ * Returned Value:
+ * None.
+ *

Review Comment:
