* configure.ac: Check for Intel TSS. * tpm2d/intel-tss.h: New. * tpm2d/tpm2.h (HAVE_INTEL_TSS): Use the Intel code. -- The Intel TSS is somewhat of a moving target, so this wraps support for this TSS into tpm2daemon. Unfortunately this wrapper uses some APIs that are only present in a relatively recent Intel TSS, so it looks like it will only work with version 2.4.0 or higher. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> - Add header blurb; see previous patch. - Add new file to the Makefile Signed-off-by: Werner Koch <wk@gnupg.org>
