Over time I will define tpmdd-x86_64 and tpmdd-aarch64 boards and everything will be then in the master branch. To create identical images you just need to $ make tpmdd_defconfig && make Can you check if you see anything obviously wrong? I'm eager to test this patch set, and in bigger picture I really need to have ready to run aarch64 environment available. /Jarkko
