It should depend on > X86_64, to be precise. I think theoretically a 32-bit host OS can invoke a PSP commands but currently PSP interface is exposing only the SEV FW command. And SEV feature is available when we are in 64-bit mode hence for now its okay to have depends on X86_64. I will add CRYPTO_DEV_CCP_DD depend on CPU_SUP_AMD || ARM64 and CRYPTO_DEV_SP_PSP depend on X86_64 and send you v4.2. thanks
