OcteonTX2 doesn't fall under ARCH_THUNDER and ARCH_THUNDER2. A better approach would be to define and use a new SOC type as Arnd mentioned at https://patchwork.kernel.org/project/linux-crypto/patch/266065918e47e8965bb6a0ab486da070278788e4.1641996057.git.geert+renesas@xxxxxxxxx/ Please wait for him to post that patch or use arm64 as dependency. Thanks, Shijith
