Would this look better if split? I.e.

      depends on CRYPTO_DEV_SP_PSP
      depends on !(I2C_DESIGNWARE_PLATFORM=y && CRYPTO_DEV_CCP_DD=m)
Yes, thanks I'll change that for next version.

I'm wondering if this is homegrown implementation of 'imply' keyword?


Like this?

config I2C_DESIGNWARE_AMDPSP
    depends on CRYPTO_DEV_SP_PSP
    depends on CRYPTO_DEV_CCP_DD

config CRYPTO_DEV_CCP_DD
    imply I2C_DESIGNWARE_PLATFORM

Looks okay, but I'm not familiar with this code. The documentation about
'imply' can be found here:

https://www.kernel.org/doc/html/latest/kbuild/kconfig-language.html#menu-attributes



Yeah I found that, but this was my first time using imply, so I was hoping someone who has used it could validate I interpreted it correctly.

Following the example CRYPTO_DEV_CCP_DD would be FOO and I2C_DESIGNWARE_PLATFORM would be BAZ so I thought so.
