Xen devel - Jan 2007 - [PATCH] [Bochs/32-Bit BIOS] [2/3] TCG Bios extensions

This patch adds TCG BIOS extensions to the high memory area along with
some often-used libc utility functions. The TCG extensions are described
here:

https://www.trustedcomputinggroup.org/specs/PCClient/TCG_PCClientImplementationforBIOS_1-20_1-00.pdf

I have tried to keep the patching with rombios.c to a minimum, but some
amount of code needs to be inserted at various locations.

The code is currently deactivated, but can be activated by setting
BX_TCGBIOS to ''1''.

All this stuff is now applied, but one chunk failed. The area of code where
you added the call to tcpa_add_bootdevice() has gone away, probably due to
Tim Deegan''s changes to support network boot. You''ll have to
work out the
new place to put it.
