Yeah, I forgot to select CRYPTO_SHA256 in Kconfig. Looks like there is a blind point in my local build tests (allyesconfig, allnoconfig, allmodconfig). The config in the build fail case could be "CROS_EC_CODEC=y" and "CRYPTO_*=n". Could you tell me how you get the .config (to enhance my local build tests next time)? I tried randconfig several times but it seems not easy to hit the case (i.e. CROS_EC_CODEC=y but CRYPTO_*=n).
