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'. Signed-off-by: Stefan Berger <stefanb@xxxxxxxxxx>
