Subject: [PATCH 2/4] x86: Rename cc_platform.c to arch/x86/coco/core.c
Date: Tue, 22 Feb 2022 21:57:38 +0300 [thread overview]
Message-ID: <20220222185740.26228-3-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <20220222185740.26228-1-kirill.shutemov@linux.intel.com>
Move cc_platform.c to the newly created arch/x86/coco. The directly is
going to be a home space for code related to confidential computing.
Intel TDX code will land here. AMD SEV code will also eventually be
moved there.
