Ok, I'll report through our ST sales representative. Anyway PINRSTF (RCC_CSR_PINRSTF) is used in arch/cm3/dev/stm/stm32_reset.c:

int Stm32ResetCause(void)
{
     uint32_t csr;
     int flags;

     csr = RCC->CSR;
     flags = 0;
     if        (csr & RCC_CSR_IWDGRSTF)  {
         flags |= NUT_RSTTYP_WATCHDOG;
     } else if (csr & RCC_CSR_WWDGRSTF)  {
         flags |= NUT_RSTTYP_WWATCHDOG;
     } else if (csr & RCC_CSR_FWRSTF)    {
         flags |= NUT_RSTTYP_FIREWALL;
     } else  if (csr & RCC_CSR_SFTRSTF)  {
         flags |= NUT_RSTTYP_SOFTWARE;
     } else if (csr & RCC_CSR_LPWRRSTF) {
         flags |= NUT_RSTTYP_LOWPOWER;
     } else if (csr & RCC_CSR_OBLRSTF)   {
         flags |= NUT_RSTTYP_OPTIONLOADER;
     } else if (csr & RCC_CSR_V18PWRSTF) {
         flags |= NUT_RSTTYP_COREPOWER;
     } else if (csr & RCC_CSR_BORRSTF)   {
         flags |= NUT_RSTTYP_BROWNOUT;
     } else if (csr & RCC_CSR_PORRSTF)   {
         flags |= NUT_RSTTYP_POWERUP;
     } else if (csr & RCC_CSR_PINRSTF)   {
         flags |= NUT_RSTTYP_EXTERNAL;
     }
     RCC->CSR |= RCC_CSR_RMVF;
     return (flags) ? flags : NUT_RSTTYP_UNKNOWN;
}
