Does the presence of SCM hardware imply SMP? From reading this, it's unclear why the dependence on SMP - it looks like scm.c is something that hardware that has one ARM processor and a 'secure processor' would still want. Or is the 'secure processor' just another (arbitrarily labeled) ARM CPU participating as a full SMP processor? --==_Exmh_1291665648_4733P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFM/UDwcC3lWbTT17ARAhT4AKDit4oYNcVR6MAXBs8z09+WAyvCWACfW6PY lzuqPN2v8vQrWGM12BlmdtM= =CdKU -----END PGP SIGNATURE----- --==_Exmh_1291665648_4733P--
