Subject: [PATCH Part1 v5 26/38] x86/compressed/acpi: move EFI config table access to common code
Date: Fri, 20 Aug 2021 10:19:21 -0500 [thread overview]
Message-ID: <20210820151933.22401-27-brijesh.singh@amd.com> (raw)
In-Reply-To: <20210820151933.22401-1-brijesh.singh@amd.com>
From: Michael Roth <michael.roth@amd.com>
Future patches for SEV-SNP-validated CPUID will also require early
parsing of the EFI configuration. Move the related code into a set of
helpers that can be re-used for that purpose.
