As I have commented elsewhere [1], I think those have been taken prematurely, and I'm not sure it's a good idea to enable this just yet, due to that. There are spec issues to be addressed in the draft that is still open. [1] https://lkml.kernel.org/r/20170411113652.GB32267@leverpostej Thanks, Mark.

Some ARM64 server systems have a Trusted Platform Module security chip on the board, and the chip is used to validate the operating system, among other things. Signed-off-by: Timur Tabi <timur@codeaurora.org> --- arch/arm64/configs/defconfig | 2 ++ 1 file changed, 2 insertions(+)
