quilt/0.48-1 |
The TPM interface (tpm_tis) needs to be explicitly enabled via
./configure --enable-tpm. This patch also restricts the building of the
TPM support to i386 and x86_64 targets since both backends I know
of, the Xen backend and the libtpms-based backend, will likely only
be available for these targets, at least initially. The list can be
easily extend. I am trying to prevent that one will end up with
support for a frontend but no available backend.
v3:
- fixed and moved hunks in Makefile.target into right place
