patch subject: [PATCH v10 20/20] x86/efi: EFI stub DRTM launch support for Secure Launch
config: i386-randconfig-062-20240828 (https://urldefense.com/v3/__https://download.01.org/0day-ci/archive/20240829/202408290030.FEbUhHbr-lkp@xxxxxxxxx/config__;!!ACWV5N9M2RV99hQ!KhkZK77BXRIR4F24tKkUeIlIrdqXtUW2vcnDV74c_5BmrQBQaQ4FqcDKKv9LB3HQUocTGkrmIwkYG0TY$ )
This is a i386 32-bit build, which makes no sense: this stuff should
just declare 'depends on 64BIT'
Our config entry already has 'depends on X86_64' which in turn depends
on 64BIT. I would think that would be enough. Do you think it needs an
explicit 'depends on 64BIT' in our entry as well?
Thanks
Ross
