kfraser@localhost.localdomain 09a4bf86cf [TPM] Set tcpa calls in the rombios and other fixes.
This patch places some tcpa calls into the rombios that had previously
not applied anymore or were not set.
Force the reads from MMIO memory locations that the compiler otherwise
optimizes away (-O2) if there was an immediate write to the same
memory location before.
Use #define'd constants wherever possible.
Fix all remaining compiler warnings.

kaf24@localhost.localdomain 2d52e184e5 [HVM] Add 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'.
