Subject: [PATCH v3 1/9] EFI: Introduce inline stub for efi_enabled on !X86 && !ARM
Date: Thu, 14 Mar 2024 17:15:39 -0500	[thread overview]
Message-ID: <39069a589f9c4dc0db9b01b7412c1a99bea55f37.1710443965.git.sanastasio@raptorengineering.com> (raw)
In-Reply-To: <cover.1710443965.git.sanastasio@raptorengineering.com>

On architectures with no EFI support, define an inline stub
implementation of efi_enabled in efi.h that always returns false.
