When EFI_EMBEDDED_FIRMWARE is selected, and CRYPTO is not selected, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for CRYPTO_LIB_SHA256 Depends on [n]: CRYPTO [=n] Selected by [y]: - EFI_EMBEDDED_FIRMWARE [=y] && EFI [=y] This is because EFI_EMBEDDED_FIRMWARE selects CRYPTO_LIB_SHA256, without selecting or depending on CRYPTO, despite CRYPTO_LIB_SHA256 depending on CRYPTO. This unmet dependency bug was detected by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution.
