There are quite a few of these

	if (tdx())
		...

conditions in common code here.  Shouldn't this be something like a
CC_ATTR_MEM_ACCEPT?

	if (cc_platform_has(CC_ATTR_MEM_ACCEPT))
		cc_accept_memory(...);
	else
		error("Cannot accept memory: unknown platform\n");

I understand that TDX is the first one to the party.  Is this the time
to add the cc_ infrastructure?
