[PULL 04/27] i386/tdx: Build TDX only for 64-bit target

Posted by Cédric Le Goater 5 months, 1 week ago

From: Xiaoyao Li <xiaoyao.li@intel.com>

Build errors related to TDX were reported when QEMU built on 32-bit
host[1][2].

Since TDX cannot work on 32-bit host and it's also not worth supporting
TDX with 32-bit QEMU, limit TDX to 64-bit target only.
