xen: TPM Emulator for Xen stubdoms
TPM Emulator is a software-based TPM and MTM emulator. This TPM Emulator recipe creates a static library that is cross-compiled against MiniOS, Xen, LWIP, Newlib, PolarSSL, and the stubdom-specific GMP headers and subsequently used during the cross-compilation and linking of the Xen vTPM and vTPM Manager stubdomains. The current Xen source code is hardcoded to fetch a specific version of this package. The patch files originate from the Xen/stubdom source tree. This recipe provides the flexibility to change version or modify the patches. Signed-off-by: Kurt Bodiker <kurt.bodiker@braintrust-us.com> Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com>
