        bool "Store phy calibration data in NVS"
        default y
        help
            If this option is enabled, NVS will be initialized and calibration data will be loaded from there.
            PHY calibration will be skipped on deep sleep wakeup. If calibration data is not found, full calibration
            will be performed and stored in NVS. Normally, only partial calibration will be performed.
            If this option is disabled, full calibration will be performed.

            If it's easy that your board calibrate bad data, choose 'n'.
            Two cases for example, you should choose 'n':
            1.If your board is easy to be booted up with antenna disconnected.
            2.Because of your board design, each time when you do calibration, the result are too unstable.
            If unsure, choose 'y'.

            If enabled, PHY init data will be loaded from a partition.
            When using a custom partition table, make sure that PHY data
            partition is included (type: 'data', subtype: 'phy').
            With default partition tables, this is done automatically.
            If PHY init data is stored in a partition, it has to be flashed there,
            otherwise runtime error will occur.

            If this option is not enabled, PHY init data will be embedded
            into the application binary.

            If unsure, choose 'n'.

        help
            If enabled, PHY init data will be restored to default if
            it cannot be verified successfully to avoid endless bootloops.

            If unsure, choose 'n'.

                If enabled, the corresponding PHY init data type can be automatically switched
                according to the country code. China's PHY init data bin is used by default.
                Can be modified by country information in API esp_wifi_set_country().
                The priority of switching the PHY init data type is:
                1. Country configured by API esp_wifi_set_country()
                and the parameter policy is WIFI_COUNTRY_POLICY_MANUAL.
                2. Country notified by the connected AP.
                3. Country configured by API esp_wifi_set_country()
                and the parameter policy is WIFI_COUNTRY_POLICY_AUTO.

                If not enabled, multiple phy init data bin will still leave alone, and need to be flashed by users.

                If enabled, when an error occurs while the PHY init data is updated,
                the program will terminate and restart.
                If not enabled, the PHY init data will not be updated when an error occurs.

            If enabled, the MAC and baseband of Wi-Fi and Bluetooth will be powered
            down when PHY is disabled. Enabling this setting reduces power consumption
            by a small amount but increases RAM use by approximately 4 KB(Wi-Fi only),
            2 KB(Bluetooth only) or 5.3 KB(Wi-Fi + Bluetooth).
