[Qemu-devel] [PATCH V1 4/8] Build the TCG BIOS extensions and TPM drivers.

[Stefan Berger <stefanb@linux.vnet.ibm.com>]

[-- Attachment #1: tcgbios_build.diff --]
[-- Type: text/plain, Size: 1515 bytes --]

This patch allows to configure the TCGBIOS extensions to be built
into SeaBIOS, depending on not COREBOOT being selected.

All TCG BIOS extensions are activated with CONFIG_TCGBIOS.

Add the two new code files (tcgbios.c, tpm_drivers.c) to be built.
