OvmfPkg/OvmfXen: Build platform info HOB in XenPlatformPei
Copy the function BuildPlatformInfoHob() from OvmfPkg/PlatformPei. QemuFwCfgLib expect this HOB to be present, or fails to do anything. InternalQemuFwCfgIsAvailable() from QemuFwCfgPeiLib module will not check if the HOB is actually present for example and try to use a NULL pointer. Fixes: cda98df16228 ("OvmfPkg/QemuFwCfgLib: remove mQemuFwCfgSupported + mQemuFwCfgDmaSupported") Signed-off-by: Anthony PERARD <anthony.perard@citrix.com> Reviewed-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Jiewen Yao <jiewen.yao@intel.com>
