Date: Mon, 29 Jan 2024 23:39:04 +0000 [thread overview]
Message-ID: <MW4PR11MB5821466B15993C47C85831F0CD7E2@MW4PR11MB5821.namprd11.prod.outlook.com> (raw)

Hi Ted,
The scenario where we have a 64-bit FSP that does not support reset vector in FSP-O is likely to happen in a future Intel platform. As such, please implement this feature in a manner that does not require all assembly code in the X64 folder to use FSP-O.
Thanks,
Nate
