Subject: x86: acpi: Include the TPMv1 table only if needed
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7f061e0d255d5cdfbd216960134ea66e474ae819;p=u-boot.git

x86: acpi: Include the TPMv1 table only if needed

This table is not needed if a v2 TPM is in use. Add a condition to avoid
adding it when not needed.
