hwcrypto的子选项全部选了，板子stm32f411

.config

提示错误

代码抄的
```https://www.rt-thread.org/document/site/programming-manual/device/crypto/crypto/#_50```

rt_hwcrypto_dev_dufault()方法在下面文件里面有
```${workspaceFolder}/rt-thread/components/drivers/hwcrypto/hwcrypto.c```

单步调试

```
static rt_err_t _crypto_create(struct rt_hwcrypto_ctx *ctx)
{
    rt_err_t res = RT_EOK;

switch (ctx->type & HWCRYPTO_MAIN_TYPE_MASK)
    {
<font color="#ff0000">#if defined(BSP_USING_RNG)</font>
    case HWCRYPTO_TYPE_RNG:
    {
        RNG_HandleTypeDef *hrng = rt_calloc(1, sizeof(RNG_HandleTypeDef));

hrng->Instance = RNG;
        HAL_RNG_Init(hrng);
        ctx->contex = hrng;
        ((struct hwcrypto_rng *)ctx)->ops = &rng_ops;

break;
    }
#endif /* BSP_USING_RNG */

<font color="#ff0000">#if defined(BSP_USING_CRC)</font>
    case HWCRYPTO_TYPE_CRC:
    {
        CRC_HandleTypeDef *hcrc = rt_calloc(1, sizeof(CRC_HandleTypeDef));
        if (RT_NULL == hcrc)
        {
            res = -RT_ERROR;
            break;
        }

hcrc->Instance = CRC;
#if defined(SOC_SERIES_STM32L4) || defined(SOC_SERIES_STM32F0) || defined(SOC_SERIES_STM32H7) || defined(SOC_SERIES_STM32F7)
        hcrc->Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_ENABLE;
        hcrc->Init.DefaultInitValueUse = DEFAULT_INIT_VALUE_DISABLE;
        hcrc->Init.InputDataInversionMode = CRC_INPUTDATA_INVERSION_BYTE;
        hcrc->Init.OutputDataInversionMode = CRC_OUTPUTDATA_INVERSION_ENABLE;
        hcrc->InputDataFormat = CRC_INPUTDATA_FORMAT_BYTES;
#else
        if (HAL_CRC_Init(hcrc) != HAL_OK)
        {
            res = -RT_ERROR;
        }
#endif /* defined(SOC_SERIES_STM32L4) || defined(SOC_SERIES_STM32F0) || defined(SOC_SERIES_STM32H7) || defined(SOC_SERIES_STM32F7) */
        ctx->contex = hcrc;
        ((struct hwcrypto_crc *)ctx)->ops = &crc_ops;
        break;
    }
#endif /* BSP_USING_CRC */
    default:
        res = -RT_ERROR;
        break;
    }
    return res;
}
```

发现是需要定义
BSP_USING_RNG
或者
BSP_USING_CRC

menuconfig里面搜索，在On-chip Peripheral Drivers里面看到相应配置，
打开 board/Kconfig，发现关键点
source "libraries/HAL_Drivers/Kconfig"

于是打开 libraries/HAL_Drivers/Kconfig

```
config BSP_USING_CRC
    bool "Enable CRC (CRC-32 0x04C11DB7 Polynomial)"
    select RT_USING_HWCRYPTO
    select RT_HWCRYPTO_USING_CRC
    # "Crypto device frame dose not support above 8-bits granularity"
    # "Reserve progress, running well, about 32-bits granularity, such as stm32f1, stm32f4"
    depends on (SOC_SERIES_STM32L4 || SOC_SERIES_STM32F0 || SOC_SERIES_STM32F7 || SOC_SERIES_STM32H7)
    default n

config BSP_USING_RNG
    bool "Enable RNG (Random Number Generator)"
    select RT_USING_HWCRYPTO
    select RT_HWCRYPTO_USING_RNG
    depends on (SOC_SERIES_STM32L4 || SOC_SERIES_STM32F4 || SOC_SERIES_STM32F7 || \
                SOC_SERIES_STM32H7)
    default n
```

我的F4, BSP_USING_CRC 不支持，难怪在menuconfig里面虽然能搜到，但是看不到，勾选了 BSP_USING_RNG，编译，报错，错误信息如下：

应该怎么弄？
