It has been discovered that the following configuration options are undefined in the current latest version, v6.3-rc4, yet they are being relied upon by other configuration options in multiple Kconfig files:
MIPS_BAIKAL_T1 is undefined, used as a 'depends on' condition in multiple files such as drivers/ata/Kconfig, drivers/hwmon/Kconfig, drivers/bus/Kconfig, and drivers/memory/Kconfig. MFD_MAX597X is undefined, used as a 'depends on' condition in Kconfig file drivers/regulator/Kconfig. MFD_SM5703 is undefined, used as a 'depends on' condition in Kconfig file drivers/regulator/Kconfig. ARCH_THUNDERBAY is undefined, used as a 'depends on' condition in Kconfig files drivers/pinctrl/Kconfig and drivers/phy/intel/Kconfig. ARCH_BCM4908 is undefined, used as a 'depends on' condition in Kconfig file drivers/leds/blink/Kconfig. MFD_TN48M_CPLD is undefined, used as a 'depends on' condition in Kconfig files drivers/gpio/Kconfig and drivers/reset/Kconfig. USB_HSIC_USB3613 is undefined, used as a 'depends on' condition in drivers/staging/greybus/Kconfig and drivers/staging/greybus/arche-platform.c.
If these 7 configuration options are deprecated, it is recommended to remove the dependencies on them in the Kconfig files. If they are still useful, it is recommended to define them.
