This patch adds an implementation of the TCG BIOS extensions to the
Bochs BIOS and enables logging of boot measurements using the previously
implemented support for TCPA ACPI tables. A low-level driver for a TPM
TIS device and an Atmel device is provided.
The implemented specification is described here:
https://www.trustedcomputinggroup.org/specs/PCClient/TCG_PCClientImplementationforBIOS_1-20_1-00.pdf
I added a #define 'BX_TCGBIOS' to rombios.c that enables or disables
these extensions. It's currently disabled so none of the code is
compiled into the BIOS.
The implementation passes the tests implemented in a newer version of
trusted grub (available through the trousers project on sourceforge).
